164-555: In the Back to the Future franchise, the DeLorean time machine is a time travel vehicle constructed from a retrofitted DMC DeLorean . Its time travel ability is derived from the "flux capacitor", a component that allows the car to travel to the past or future (though not through space). This occurs when the car accelerates to 88 miles per hour and requires 1.21 gigawatts of electricity. In 2021,

328-578: A motion-simulation ride at the Universal Destinations & Experiences in Universal City, California ; Orlando, Florida ; and Osaka, Japan (all now closed), as well as a video game and a stage musical . The film's visual effects were done by Industrial Light and Magic . The first film won an Academy Award for Sound Editing . Seventeen-year-old Marty McFly is accidentally sent back in time from October 26, 1985, to November 5, 1955, in

492-419: A paradox that would prevent Marty's existence. Without plutonium to power the time machine, Marty must find the 1955 Doc Brown to help him reunite his parents and return to 1985. The efforts of Biff Tannen , George's bully and supervisor, further complicate Marty's situation until Marty successfully causes his parents to fall in love and simultaneously convinces George to finally stand up to Biff. Returning to

656-417: A plutonium -fueled nuclear reactor. In the first film, following Marty's accidental trip from 1985 to 1955, Doc has no access to plutonium in 1955, so he outfits the car with a large pole and hook to channel the power of a lightning bolt into the flux capacitor and send Marty back to 1985. During Doc's first visit to 2015, he has the machine refitted to fly in addition to standard road driving, and he replaces

820-400: A schematic diagram in the time machine to enable his 1955 counterpart to repair it using components from that era – which included vacuum tubes — before boarding it up within a silver mine. He then writes Marty a letter explaining the situation and places it in the custody of Western Union , with instructions to deliver it to Marty in 1955. The Mr. Fusion Home Energy Reactor is the name of

984-450: A "jigowatt" referring to "one billion watts". The spelling of "jigowatts" is used in the script and was also the spelling used in the closed-captioning in earlier home video versions of the film. However, the correct spelling is " gigawatts ". Although rarely used, the "j" sound at the beginning of the SI prefix "giga-" is an acceptable pronunciation. Later versions of closed captioning, such as in

1148-568: A 1979 law passed by then-President Jimmy Carter had limited speedometers to 85   mph to reduce speeding. The Flux Capacitor, necessary for time travel, was called the Temporal Field Capacitor; Zemeckis said the name was not believable. From his work on the 1979 drama The China Syndrome , Fink had learned of Neutron flux . He and Zemeckis simultaneously suggested renaming it the Flux Capacitor. Cobb and Probert had already placed

1312-527: A 2008 fan convention in Florida, stating: "The idea of making another Back to the Future movie without Michael J. Fox – you know, that's like saying, 'I'm going to cook you a steak dinner and I'm going to hold the beef. ' " Gale also said that the Telltale video-game adaptation is the closest thing to what a fourth film could be like. In an interview on October 21, 2015, the day of Marty McFly's purported arrival in

1476-539: A back seat in normal two-door mode, the ability to transform into a four-door, a pop-out covered wagon top, a blimp, a rear video screen, and a voice activated time input. Back to the Future: The Game features a chronal duplicate of the original DeLorean, which Doc Brown recovered from the timestream after the destruction of the original. This DeLorean is created at the end of Back to the Future Part II ; when

1640-447: A cinema-by-cinema basis slowly reopened. Many cinemas also showed the rest of the trilogy, partially due to the coinciding 30th anniversary of Part III . Marty McFly and Doc Brown were included in Empire ' s 100 Greatest Movie Characters of All Time, ranking No. 39 and No. 76 respectively. October 21, 2015, the date used for the setting of the future events during the first act of

1804-399: A combination of live-action footage, animation, and a 1:5 scale (approximately 33 inches (840 mm) long) model built by Steve Gawley and the model shop crew and filmed against a blue screen . Months were spent building the model from epoxy, steel, and aluminum. Halogen lamps were fitted to the tires to simulate thrusters; the tires were made from aluminum to withstand the heat. Blue chalk

1968-487: A falling out between the duo, Citizen Brown leaves in the alternate Clone DeLorean and picks up Edna Strickland, one of the game's main villains, having decided to have her help change his younger self's career after learning of Edna's unhappy future. Marty foils their attempts, leading Edna to steal the alternate Clone DeLorean with Officer Parker in pursuit. The original Doc arrives in the original Clone DeLorean as Citizen Brown disappears from existence due to earlier events in

2132-470: A forced exhaust system, they have the advantage of not always requiring a vertical rise to vent, although a 3-to-5-foot (0.91 to 1.52 m) vertical run to induce some draft is recommended to prevent leakage in the case of a power outage. Like a modern gas appliance, pellet stoves can be vented horizontally through an outside wall and terminated below the roof line, making it an excellent choice for structures without an existing chimney. If an existing chimney

2296-421: A lower grade pellet, and that inconsistent wood quality can cause serious effects to the electronic machinery over a short period of time. A pellet stove is normally associated with pelletized wood. However, many pellet stoves will also burn fuels such as grain, corn, seeds, or woodchips . In some pellet stoves, these fuels may need to be mixed with wood pellets. Pelletized trash (containing mostly waste paper)

2460-481: A message for Marty McFly. He explains that it is October 21, 2015, one hour before Marty, Doc, and Jennifer Parker arrive from 1985. He explains that when he traveled to the future, he discovered that there was a nuclear holocaust that occurred on October 21, 2045. He tracked it down to four inventions: the food hydrator, self-lacing shoes, the hoverboard, and the Mr. Fusion home energy reactor. The former three inventions led to

2624-475: A nearby wall. The Clone DeLorean is later restored by an alternate version of Doc Brown (who took six months to repair it) who has never developed time travel technology, having access to limited notes about the flux capacitor. After traveling six months back in time, he picks up Marty and they return to 1931. As such, the time circuits of the alternate Clone DeLorean become even more glitchy (resulting in them arriving two months late), accumulating errors as severe as

2788-651: A new automatic retrieval feature that automatically brings the Clone DeLorean to a set time and location of Doc's choosing every time Doc doesn't return to the car in a fixed amount of time. The original DeLorean made a brief appearance in Marty Mcfly's nightmare where Doc sends it one minute into the future, which copies the events of the first film. The only difference is that it does not return from its one-minute trip. The Clone DeLorean appears outside of Doc's house after Marty recovers Doc's notebook from Biff Tannen. Inside

2952-468: A power source used by the DeLorean time machine in the Back to the Future trilogy . It can be seen for the first time at the end of Back to the Future when Doc pulls into the McFly's driveway after a trip to the year 2015. It was a piece of technology he was only able to obtain due to his journey to 2015, which in the movie existed by then. It is a parody of Mr. Coffee machines, which were very popular at

3116-433: A project lined up but agreed to help in the free weeks he had remaining. Three DeLoreans used were purchased from a collector—one for stunts, one for special effects, and one for normal shots. They were unreliable and often broke down. 88 mph (142 km/h) was chosen as the time travel speed because it was easy to remember and looked "cool" on the speedometer. A custom speedometer was built to simulate 88   mph, as

3280-408: A rectangular-shaped compartment with three flashing Geissler-style tubes arranged in a "Y" configuration, is described by Doc as "what makes time travel possible". The device is the core component of the time machine. As the time machine nears 88 mph, light coming from the flux capacitor begins pulsing more rapidly until it becomes a steady stream. Doctor Emmet Brown originally conceived the idea for

3444-416: A series of cast-iron or steel heat exchangers that run along the back and top areas of the visible firebox. With a convection blower, room air is circulated through the heat exchangers and directed into the living space. This method allows for a much higher efficiency than the radiant heat of a hand-fed wood or coal stove, and will in most cases cause the top, sides, and back of the stove to be at most warm to

3608-404: A set designed to mate with train rails. For the extra power needed to push it up to speed, Doc adds his own version of " Presto Logs " (a chemically treated mixture of pressed wood and anthracite ) to the locomotive's boiler and chooses a location with a straight section of track long enough to achieve 88 mph. The power required is pronounced in the film as "one point twenty-one jigo watts", with

3772-533: A special screening of the trilogy was held in Celebration, Florida . Bob Gale told the crowd they were seeing the digitally remastered version that was going to be used for the Blu-ray version of the movies. The Blu-ray box set was released on October 26, 2010, and includes bonus features, such as a newly produced six-part retrospective documentary titled Tales from the Future . There have been numerous complaints about

3936-617: A success. Both versions of Brown, along with the artificial intelligence of the Quantum Mind Jar, are shocked at discovering that there are two Emmett Browns present. An animated television series, Back to the Future: The Animated Series , lasted two seasons, each featuring 13 episodes, and ran on CBS from September 14, 1991, to December 26, 1992. The TV series Back to the Future was an animated science-fiction comedy adventure television series for television, based on

4100-416: A time machine built from a DeLorean by eccentric scientist Emmett "Doc" Brown , when they are attacked and Doc is apparently killed by Libyan terrorists from whom he stole the plutonium that gives the flux capacitor the 1.21 gigawatts it needs to time-travel. Soon after his arrival in 1955, Marty's mother, Lorraine , falls in love with him, rather than with his father George McFly , threatening to cause

4264-491: A time machine, restoring most of its features, including Mr. Fusion and the hover conversion (Doc either rebuilds the one destroyed at the end of Part III or he simply builds a new one). He also seemingly adds the capability to travel through space in addition to time (i.e., appear at a different location from the one it departed), similar to the TARDIS from Doctor Who . The cartoon DeLorean time machine has many add-ons, including

4428-406: A viable, economical, and popular option for home heating systems only in the last ten years. Between 1998 and 2010, 824,410 pellet stoves and fireplace inserts were made in the U.S. While some stoves are UL-listed for fuels other than pellets, such as wheat, corn, sunflower seeds, and cherry pits, many pellet stove manufacturers recommend the use of a corn and pellet mixture. The pellet fuel

4592-502: Is Einstein, a tape recorder with a message from Doc that tells Marty about the automatic retrieval system, and a mysterious shoe. After learning that Doc is stuck somewhere in time, he activates the time circuits, but the last time departed time display is faulty, forcing Marty to use Einstein and the shoe to find out Doc's whereabouts. He eventually learns that Doc is in 1931 and will be killed by Irving "Kid" Tannen, Biff's father. Marty travels to 1931, one day before Doc's death, appearing in

4756-435: Is a consistent heater consuming fuel that is fed evenly from a refillable hopper into the burn pot (a perforated cast-iron or steel basin), through a motorized system. The most commonly used distributor is an auger system that consists of a spiral length of metal encased in a tube. This mechanism is either located above the burn pot or slightly beneath and guides a portion of pellet fuel from the hopper upwards until it falls into

4920-468: Is also a fuel for pellet stoves. Unlike wood stoves, which operate exclusively on a principle of chimney draft, a pellet stove must use a specially sealed exhaust pipe to prevent exhaust gases escaping into the living space due to the air pressure produced by a combustion blower. Pellet stoves require certified double-walled venting, normally three or four inches in diameter with a stainless steel interior and galvanized exterior. Because pellet stoves have

5084-421: Is available, manufacturers urge use of a correctly sized stainless steel liner the length of the chimney for proper drafting. Modern building techniques have created tightly sealed homes, forcing many pellet stove manufacturers to recommend their stoves be installed with outside air intake to ensure the stoves will run efficiently and prevent potential negative pressure within the home. In many states pellet fuel

5248-459: Is delivered from the storage facility or the day tank (single stoves) into the combustion chamber. With the heat generated, circuit water is heated in the pellet boiler. In central heating systems the hot water then runs through the heating circuit. The heat distribution is the same as other central heating systems. Unlike oil or gas heating, the inclusion of a hot water reservoir is recommended with pellet heating systems to save hot water until it

5412-460: Is exempt from sales tax. Until January 1, 2012, in most states in the U.S., a 75% efficient pellet stove was eligible for a tax credit up to 30% of the cost of the appliance as part of the 25C provision, plus labor. A pellet stove normally consists of these components, whether basic or complex: To properly function, a pellet stove uses electricity and can be connected to a standard electrical outlet. A pellet stove, like an automatic coal stoker,

5576-472: Is happy in his new life there as a blacksmith, and requests that Marty not attempt to retrieve him, but instead to return to 1985 and destroy the DeLorean, believing that it has brought them and the world nothing but disaster. However, Marty and 1955 Doc learn that just nine months after arriving in 1885, Doc will be murdered by Biff's great grandfather, Buford "Mad Dog" Tannen, on September 7, 1885. For this reason,

5740-414: Is needed. Most pellet stoves are self-igniting and cycle themselves on and off under thermostatic control. Stoves with automatic ignition can be equipped with remote controls. Recent innovations include integrated microcontroller monitoring of various safety conditions and can run diagnostic tests if an imminent problem arises. A properly cleaned and maintained pellet stove should not create creosote ,

5904-416: Is no longer being produced. A comic book series was published by Harvey Comics in 1992 detailing further adventures of the animated series. Only seven issues were produced. IDW published a mini-series which presents the first meeting of both Marty and Doc Brown and is written by co-screenwriter Bob Gale, which was released in stores on October 21, 2015, the same date that Marty travels with Doc Brown to

6068-400: Is not yet available. The test fails, damaging the car's fuel injection manifold and leaving it unable to travel under its own power. Doc and Marty consider options to reach the required 88 mph (such as pulling it with horses, which fails because the car barely breaks 30 mph) and ultimately settle on pushing the car with a steam locomotive. They replace the DeLorean's standard wheels with

6232-542: Is seen in a video promoting the film, though it is not specified whether it houses a flux capacitor. Universal Studios special effects department built three main DeLorean time machines for the movie Back to the Future . The film's producers characterized the DeLoreans with three names: the A car, B car, and C car. The "A" car, also known as the Hero car, was the most detailed and utilized vehicle during production. After filming

He is worried that not doing so will unravel everything they accomplished. The artificial intelligence of the Quantum Mind Jar tells Brown that they need to go back to the future, which he dismisses as he does not want to risk further time travel. Another Emmett Brown then arrives, also declaring his experiment

6560-412: Is similar to a pellet stove. The chief difference between a pellet stove and a dedicated corn stove is the addition of metal stirring rod within the burnpot or an active ash removal system. These vary in design slightly, but usually consist of one long metal stalk with smaller rods welded at a perpendicular angle, in order to churn the burn pot as it spins. An active ash removal system consists of augers at

6724-419: Is transported to January 1, 1885. Both the DeLorean's time circuits and flying capability are disabled in the process, though not the internal combustion engine. Because suitable replacement parts to repair the DeLorean will not be invented until 1947, Doc hides the DeLorean in a mine, and leaves a letter to be delivered to Marty by Western Union in 1955, in which he explains what happened to him. Doc states he

The trilogy was re-released in certain countries worldwide on October 21, 2015, to commemorate the date traveled to by the protagonists in Back to the Future Part II and generated $ 4.8 million on its opening day. In the United States and Canada, it earned $ 1.65 million from ticket sales across 1,815 North American theaters on its opening day. Germany opened with $ 1.4 million and

7872-438: The 1955 Doc and Marty agree to have Marty travel back in time to 1885 to prevent Doc's murder. After retrieving the DeLorean from the mine, repairing its time-travel ability, and replacing its since-disintegrated tires with whitewalls (although they could not restore its flight systems), Marty travels to 1885, but the DeLorean's fuel line is damaged soon after he arrives there. After encountering his ancestors, Marty decides to use

8036-473: The 2015 McFly home, 2015 Biff steals the DeLorean time machine and gives the book to his 1955 self just before he goes to the dance at the end of the first film. When Doc and Marty return to 1985, they find that Biff has used the sports almanac's knowledge for financial gain, which allowed him to turn Courthouse Square into a casino with 27 floors, take over Hill Valley, get away with the murder of Marty's father, and later marry Marty's mother. Marty learns that Biff

8200-446: The 2020 DVD Trilogy release have corrected the spelling to "gigawatts". In the DVD commentary for Back to the Future , Bob Gale states that he had thought it was pronounced this way because it was how a scientific adviser for the film pronounced it. The "jigowatts" spelling is used by Alan Dean Foster in the novelizations of the second and third films. The flux capacitor , which consists of

8528-425: The DeLorean appears in 1985, a modern train destroys it, with Marty barely escaping. Reuniting with Jennifer, Marty avoids a street race and the two visit the scene of the wreckage of the DeLorean. Suddenly, Doc, Clara and their children appear in a time-travelling steam locomotive. Doc reminds Marty and Jennifer that "[their] future is whatever [they] make it", so they must "make it a good one". The locomotive lifts off

8692-461: The DeLorean because it offered mobility, a unique design, and would appear like an alien UFO to a 1950s family due to its characteristic gullwing doors (which were inspired by the Mercedes-Benz 300 SL ). The original ending of the 1985 film Back to the Future was to have Marty outrun a nuclear explosion at a test site to power the DeLorean's flux capacitor to travel back to 1985. However, during

The destination time display shows the date that the operator wants the DeLorean to go to (when the operator types in a date using the keypad in the DeLorean, it will be shown in the destination time display), the present time display shows the DeLorean's current location in time, and

9020-410: The DeLorean from 1955 to 1885. Though the vehicle was in mid-air, the spin created by the lightning bolt allowed it to reach 88 mph. Doc is trapped in 1885 and repairs were impossible because the time circuit control microchip , which governed the time circuits, was destroyed by the lightning bolt, and suitable replacement parts would not be invented until at least 1947. Doc places repair instructions and

Once in 1885, the DeLorean had one final set of modifications: the tires were again replaced with train wheels and a temperature gauge was attached to the boiler of the stolen locomotive and mounted on the dashboard. For most of

9348-478: The DeLorean is struck by lightning with him inside. In the third film, a note left by Doc's 1885 self reveals that the DeLorean's flying circuits (added by him in 2015) were destroyed by the strike. After Marty travels back to 1885, the fuel line and fuel injection manifold both suffer damage, leaving the car unable to move under its own power. The time machine is electric and requires a power input of 1.21 gigawatts (1,620,000 hp) to operate, originally provided by

9512-427: The DeLorean itself, which makes use of an ordinary gasoline combustion engine to reach the 88 mph speed necessary for it to time travel. This limitation proved crucial in the third movie when Doc and Marty find themselves stuck in 1885 and unable to drive the DeLorean due to a punctured fuel line. The vehicle's hover system is powered by Mr. Fusion and is capable of bringing the DeLorean up to the required 88 mph. However,

On October 20, 2015, one day before the date of the fictional events transpiring in the 2015 segment of Part II , the trilogy was once again released on Blu-ray and DVD. A bonus disc was included, which featured new bonus material such as Outatime which is a look into the restoration of

11972-520: The United Kingdom with $ 345,000. Revenues from other territories such as Australia, Austria, France, Italy were moderate. The first movie in the trilogy returned to certain countries once again for the 35th anniversary of the first film. In the United Kingdom, this was originally scheduled to begin on May 29, 2020, but due to the COVID-19 pandemic the opening dates of various cinemas were delayed, and on

12136-416: The World is a 2015 direct-to-video short film starring Christopher Lloyd as Emmett Brown. The short debuted on the 2015 Blu-ray and DVD release of the Back to the Future trilogy commemorating the franchise's 30th anniversary. The short was released on October 20, 2015.

12300-435: The alias Clint Eastwood . After meeting up with the 1885 Doc, the fuel line is repaired, but their experiments with creating modern fuel from whiskey destroys the fuel injection manifold, leaving the car unable to travel under its own power. After trying a few ideas (such as pulling it with horses), they resolve to use a steam locomotive to push the DeLorean up to 88 mph. They learn that for the locomotive to reach 88 mph,

12464-474: The almanac by his future self. The latter is also co-written by Gale. Transformers/Back to the Future is a four-issue crossover comic miniseries published by IDW Publishing, to commemorate the 35th anniversaries of Back to the Future and Hasbro 's Transformers franchise. It was published from October 7, 2020, to May 12, 2021. A Japanese light novel adaptation was announced in August 2021. Each film in

12628-409: The auger tube causing a hopper fire. As safeguards, all pellet stoves are equipped with heat sensors, and sometimes vacuum sensors, enabling the controller to shut down if an unsafe condition is detected. For daily maintenance, an ash vacuum is recommended. These are similar to shop vacs, but are designed for the removal of ash materials. These vacuums are available with a pellet stove kit which enables

12792-409: The burn pot for combustion. Fan systems are necessary for clean, economical performance. The flame produced is concentrated and intense in the small area of the burn pot as a combustion blower introduces air into the bottom of the burn pot, while also forcing exhaust gases into the chimney. While some pellet stoves will be hot to the touch (especially on the viewing window), most manufacturers utilize

12956-469: The car on display at Hubbardston, Massachusetts . The time machine went through several variations during production of the first film, Back to the Future . In the first draft of the screenplay, the time machine was a laser device that was housed in a room; at the end of the draft the device was attached to a refrigerator and taken to a nuclear bomb test . Spielberg vetoed the idea, concerned that children might attempt to climb into one. Zemeckis suggested

13120-465: The car to a private company and the vehicle is currently being displayed on the company's entryway. There were three extra DeLoreans used through the production of the sequels . The fiberglass car used on special effects was reportedly destroyed. The stunt train, better known as The Oxnard Car, was displayed in Universal Studios, Florida , from the early 1990s to 2020. The studio decided to replace

13284-436: The car's body. Vents on the back heat the vehicle after time travel. The DeLorean suffers assorted malfunctions and damage over the course of the trilogy. In the first film, the car has starter problems and has a hard time restarting once stopped, much to Marty's repeated frustration. In the second film, the destination time display malfunctions and begins to show a series of random dates, causing Doc to be sent back to 1885 when

13448-415: The cleaning of the interior areas of the stove which improves efficiency. Pellet stoves can either be lit manually or through an automatic igniter. The igniter piece resembles a car's electric cigarette lighter heating coil. Most models have automatic ignition and can be readily equipped with thermostats or remote controls. A corn stove is designed for whole-kernel shelled corn kernel combustion and

13612-405: The dashboard to signal Marty when he needed to begin accelerating towards the clock tower, and a hooked pole used to channel a lighting strike into the flux capacitor. After the DeLorean returned to 1985, the pole remained behind in 1955. In 2015, the DeLorean was given the ability to fly along with a barcode license plate to replace its old one. In the third film, after Marty and 1955 Doc recovered

13776-439: The decorative stove. These units can be retrofitted into existing home heating systems with only minor changes to existing ductwork and or plumbing. The heating industry has considerably shifted toward biomass stoves and heating devices based on efficient combustible and renewable resources. This was a trend that began with the 1973 oil crisis causing the creation of the first pellet stoves. Even so, pellet stoves have become

13940-413: The destination (red), present (green), and last departed (yellow) dates and times. After entering a target date with the keypad inside the DeLorean, the operator accelerates the car to 88 mph (142 km/h), which activates the flux capacitor. As it accelerates, several coils around the body glow blue/white while a burst of light appears in front of it. Surrounded by an electric current similar to a Tesla coil ,

14104-598: The early 20th century easily seen in the use of barrel stoves, braziers, and oil drum fires in depression-era Hooverville historical media. Professionally built wood-fired ovens with sawdust hoppers were used in the early part of the 20th century. All of these units used scrap wood or sawdust. In 1930, the Presto-Log was invented reusing scrap sawdust from the Potlatch pine mill in Lewiston, Idaho for domestic heat. From this came

14268-429: The end of the track, the DeLorean disappears to 1985 with Marty, though Doc decides to stay behind with Clara, since "Mad Dog" Tannen is arrested for a stagecoach robbery, and Doc's murder is prevented. The locomotive falls down the cliff. Back in 1985, the DeLorean arrives on the now-completed bridge and crosses over the ravine, now called Eastwood Ravine on account of his exploits in 1885. The DeLorean becomes stuck on

14432-470: The entire town of Hill Valley disappears around them; Edna had unwillingly time traveled to 1876. They go to "Mary Pickford's" house and see that the alternate Clone DeLorean had been destroyed. After they get information from Mary, who was really Edna, they go to 1876. After they stop the fire that would've burned down Hill Valley, they chase down Edna, who is trying to get away in the alternate Clone DeLorean. Marty hoverboards to Edna's DeLorean and synchronizes

14596-448: The episode, alluding to Thomas F. Wilson 's career as a stand-up comedian . This section includes characters who will appear or have appeared in two or more installments in the franchise. As of June 2011 , the Back to the Future series is the 14th-highest-grossing trilogy of all time at the domestic market (adjusted for inflation), 17th-highest-grossing trilogy of all time at the domestic market (not adjusted for inflation), and

14760-420: The family dog, Einstein . As with the films, time travel was achieved through the use of a modified DeLorean , which had apparently been re-built after it was destroyed at the end of the trilogy. The DeLorean now has voice-activated "time circuits" and can also travel instantaneously to different locations in space and time, in addition to folding into a suitcase. The characters also travel through time using

14924-462: The films do not describe exactly how the flux capacitor works, Doc mentions at one point that the stainless steel body of the DeLorean has a direct and influential effect on the "flux dispersal", but he is interrupted before he can finish the explanation. The explanation is finished in BTTF's "Delorean Time Machine; Doc Brown's Owners' Workshop Manual", which says "However, the stainless-steel construction of

15088-411: The final episode. A.J. LoCascio provided the voice for Marty McFly, and Bob Gale assisted with the script. Thomas Wilson reprised his role as Biff Tannen in the 2015 re-release. The plot of the video game depicts Marty traveling back to 1931 to help Doc, who is in trouble again. The video game depicts several trips by Marty and Doc back and forth from 1931 to the present, due to multiple disruptions to

15252-529: The first film, the 1.21 gigawatts are supplied by a plutonium-powered nuclear fission reactor and, with the absence of plutonium, a bolt of lightning channeled directly into the flux capacitor by a long pole and hook in the film's climactic sequence. At the end of the first film, and for the remainder of the trilogy, the plutonium nuclear reactor is replaced by a "Mr. Fusion Home Energy Reactor" generator possibly acquired in 2015. The "Mr. Fusion" device apparently converts household waste into electrical power;

15416-525: The first five comics in the series. The series has now gone on to what IDW calls "chapter 2" of the series with "Tales from the Time Train". This is a series of stories detailing where Doc and the Brown family went after time traveling at the end of Back to the Future Part III . Other mini-series published by IDW include "Citizen Brown", which adapts the Telltale video game , and "Biff to the Future", which depicts Biff Tannen's rise to power after being given

15580-515: The first time. The set included a new digitally remastered 4K picture, Dolby Atmos sound, and more previously unreleased content. The Back to the Future: Back in Time board game was released in 2020. It is a fully cooperative game, in which each player is a character in the film, and must collect items to help Marty McFly and Doc to return from 1955 to their own time, as depicted in the first film in

15744-408: The flight systems are destroyed as a result of the lightning strike that occurs at the end of the second film, leaving Marty to rely on the original combustion engine, which is also disabled. Besides the flux capacitor, the time circuits, and the Mr. Fusion chamber, the DeLorean had numerous other equipment that aid its ability to function: a keypad used to type in a target date, a lever that activates

15908-493: The flux capacitor on November 5, 1955, when he slipped on the edge of his toilet while hanging a clock in his bathroom and hit his head on the sink. In 1955 "Doc" had named the flux capacitor the "Flux Compresser" as shown on 1955 "Doc's" diagram. A similar flux capacitor is also seen in the chimney headlamp of Doc's second time machine, the Time Machine Locomotive, at the end of Back to the Future Part III . Although

16072-400: The flux capacitor, by which he marks the day he invented time travel, November 5, 1955, as he explains to Marty in the beginning of the first film. During the second film, because of Biff Tannen's tampering following his theft of the DeLorean, the time circuits began malfunctioning, displaying January 1, 1885, in the destination time display. A bolt of lightning triggers the malfunction to send

16236-422: The future , Christopher Lloyd stated that he would consider making a fourth film under the condition that the original cast and creative team returned, along with a story "worth telling". The same day, Lloyd reprised his role as Doc Brown in a brief segment in which the character returns with a special message marking the 2015 date. In 2020, actor Tom Holland claimed in an interview with BBC Radio 1 that he

16400-406: The future depicted in the storyline for Part II. In issue #3, it was revealed that it had become an ongoing monthly comic due to popular demand. Beginning in issue #6, the original format of one or two untold stories per issue was replaced with a multi-issue ongoing story arc. The original subtitle for the comic, "Untold Tales and Alternate Timelines", was used for the trade paperback which contained

16564-430: The future via a lightning strike that powers the machine, Marty discovers a vastly improved situation for the McFly family, as a much more confident George has become an accomplished science fiction author, Marty's two older siblings have better lives, he owns the car of his dreams, and an apparently-softened Biff is now an auto detailer, rather than George's supervisor. Despite 1955 Doc's insistence on not knowing details of

16728-416: The future, a note Marty leaves in his pocket on November 12, 1955, prevents him from being killed by the terrorists. In the film's final moments, Doc Brown appears in a modified version of the DeLorean and tells Marty and his girlfriend Jennifer Parker that they must travel to the future to fix a problem caused by Marty and Jennifer's kids. The series continues as Doc Brown travels with Marty and Jennifer to

16892-435: The game; i.e., because Marty restored the original timeline (the events of all three films), the original Doc and Clone DeLorean are brought back into existence. Officer Parker nearly arrests Marty and Doc for allegedly having the car that Edna got away in. After they explain to him that there is more than one DeLorean, Marty explains to Doc that the alternate Clone DeLorean had malfunctioning time circuits. To make matters worse,

17056-497: The history of the fictional town of Hill Valley, California . The first Back to the Future film was the highest-grossing film of 1985 and became an international phenomenon, leading to the second and third films , which were back-to-back film productions , released in 1989 and 1990, respectively. Though the sequels did not perform as well at the box office as the first film, the trilogy remains immensely popular and has yielded such spin-offs as an animated television series and

17220-438: The hook makes contact with the cable while the DeLorean is accelerating at 88 mph. Despite setback involving the cable being disconnected by a fallen branch and the DeLorean having starter problems again, the plan succeeds, and Marty returns home, arriving eleven minutes before he left 1985 to warn Doc of his upcoming death since 1955 Doc wouldn't listen out of fear of changing history. With the DeLorean once again having issues with

17384-450: The internet, but it was a scam, as it allowed Griff to gain access to every object on Earth. On the 30th anniversary of his arrest, on October 21, 2045, he uploaded a virus that was supposed to flash the word "butthead" on everything. However, it short-circuited the Mr. Fusion network, causing nuclear explosions in 100 million homes worldwide. Doc Brown travels to an unknown date to ensure these inventions are never created, which will prevent

17548-455: The interval of time traveled, with increasing damage with every time travel attempt: as such, Citizen Brown, the alternate version of Doc, has to install a diagnostic console made of materials available in 1931 (appearing as a plywood box with a diagnostic lightbulb and three similar bulbs placed on the coils on the outer body). Apparently, part of the problem is chromium parts becoming unstable during time travel, according to Citizen Brown. After

17712-454: The last time departed display shows what point in time the DeLorean originally was after making a journey through time. Doc demonstrated its capabilities to Marty after its first test, giving two well-known but erroneous dates as examples: the signing of the Declaration of Independence , July 4, 1776; and the birth of Christ, December 25, 0000. He also displayed the day that he first conceived of

17876-417: The live-action film trilogy. Although the series takes place after the films, creator Bob Gale stated that the animated series take places in its own alternate timeline. The show lasted two seasons, each featuring 13 episodes, and ran on CBS from September 14, 1991, to December 26, 1992, with reruns until August 14, 1993. The network chose not to renew the show for a third season (citing low ratings). It

18040-465: The location of the original DeLorean in time. The original DeLorean is shown to have its original "OUTATIME" license plate instead of the bar code license plate, but it could just mean that this DeLorean is actually a new one being built into a time machine. Doc can be seen traveling in the original DeLorean in the ride's queue videos. In the attraction, Biff Tannen (who stowed away in one of the institute's time machines that had recently visited 1955) steals

18204-548: The major functions of the DeLorean: the flux capacitor, the time circuits, and the plutonium chamber that powers them. After refueling the DeLorean with plutonium stolen from Libyan terrorists (who previously stole the plutonium from a power plant), Doc prepares to travel into the future, but the Libyans unexpectedly arrive and shoot Doc. Marty uses the DeLorean to flee from the Libyans and is transported to 1955 after accidentally activating

18368-520: The middle of a police chase (the glitch in the time circuits is resolved after the police car bumps into the Clone DeLorean). After getting away from the police, he hides the Clone DeLorean behind a sign. After rescuing Doc, they prepare to return to 1986, but Marty discovers that he is disappearing; it turns out his grandfather Artie Mcfly will be killed by Kid as a result of Marty's earlier actions. Upon being caught by Officer Danny Parker, Marty swipes

18532-534: The miniaturized pellet stove, which emerged from Washington State in the 1980s. The pellet stove changed in appearance over the years from a simple, boxy workhorse design, to a modern heating appliance. Pellet stoves can be either free-standing units or fireplace inserts vented into an existing chimney. Most pellet stoves are constructed using large, heat-conductive, steel or cast-iron pieces, with stainless steel to encase circuitry and exhaust areas. Pellet furnaces and pellet boilers are also available in addition to

18696-455: The movie's filming, it went over budget and behind schedule, and Universal refused to grant the producers more money, as it couldn't afford the desert location to shoot such scenario. Ultimately, the power source was changed to the lightning strike at the clock tower in Hill Valley as a result. The DeLorean was developed under the supervision of Lawrence Paull, who designed it with artist Ron Cobb and illustrator Andrew Probert. They intended for

18860-483: The name suggests nuclear fusion . Due to a "hover conversion" made in 2015, the car also becomes capable of hovering and flight, though it lost this ability at the end of the second film. After acquiring the DeLorean and modifying it into a time machine, Doc brings it to the Twin Pines Mall and tests it out by using a remote control to send it one minute into the future with his dog Einstein in it. He also shows Marty

19024-438: The nuclear explosion. He leaves his camera on, which captures the inventions being erased from history. He arrives back in 2015, in a winter jacket and ski goggles, declaring that the mission was more complicated than he calculated, but declaring it a success. He holds up the tablet computer, where the headline on the Hill Valley Telegraph changes from "Griff Tannen Founds Grifftech" to "Griff Tannen Found Guilty". Doc's excitement

19188-430: The nuclear reactor with a Mr. Fusion generator that uses garbage as fuel. Although the Mr. Fusion unit provides the required power for the time machine, the DeLorean is still powered by an internal combustion engine for propulsion. The fuel line is damaged during Marty's trip to 1885 in Back to the Future Part III . After he and Doc patch it, they attempt to use whiskey as a replacement fuel since commercial gasoline

19352-422: The only source for the power needed to return the DeLorean to 1985 is a bolt of lightning that they know from history will strike Hill Valley Courthouse's clock tower at 10:04 pm on the coming Saturday, November 12. Doc installs a cable leading from the top of the clock down to the street to harness the lightning, and attaches a long pole and hook to the DeLorean to channel the energy into the flux capacitor once

19516-623: The original Data East version and features 3-D animated figures and visual effects that are impossible to reproduce on a physical table. Back to the Future: The Musical is a stage musical with original music and lyrics by Alan Silvestri and Glen Ballard , and a book adapted from the original screenplay by Robert Zemeckis and Bob Gale. The show features hit songs from the film, including " The Power of Love " and " Johnny B. Goode ". Originally slated to première in London's West End in 2015,

19680-408: The original DeLorean (which can be seen in the ride and in the outside display) and the Time Train (which can only be seen in display outside of the attraction). Unlike the original DeLorean, the flux capacitor is in the front of the cockpit along with a small screen, the time circuits, the keypad, and the speedometer. It is also equipped with a sub-ether time-tracking scanner that allows Doc to pinpoint

19844-441: The original DeLorean, prompting Doc to send the riders to the 8-passenger DeLorean and use it to go after Biff. The ride begins with the 8-passenger DeLorean traveling to 2015 Hill Valley where it chases Biff across the town. Biff and the riders then travel to the ice age where the 8-passenger DeLorean experiences a temporally engine failure after Biff causes an avalanche that damages it. The 8-passenger DeLorean catches up to Biff in

20008-424: The original car with a replica to be stored for restoration. The desert car with the blue cross over tube was left at Universal Studios Hollywood; Tom Talmon Studios used parts of this car on a replica displayed on Universal Japan. After Japanese workers stole some of the car props, ScreenUsed acquired the car for restoration and then settled the car for auction. Bill and Patrick Shea ended up buying it, and they placed

20172-480: The original time machine was struck by lightning: while the DeLorean itself is sent to 1885, a fully functional duplicate appears (apparently unmanned and undamaged) in 2025, where Doc retrieves it with the Time Train before Griff Tannen could. This Clone DeLorean is effectively the same as the Part II one, including the occasional glitches in the time circuits (mostly affecting the last time departed time display), but with

20336-410: The original timeline, Clara fell to her death in the ravine, which was renamed Clayton Ravine. After her rescue, Doc and Clara begin to fall in love. Marty and Doc continue their plan, in which the Mr. Fusion unit will provide the power required to activate the flux capacitor and make the jump through time once the stolen locomotive and the DeLorean reach 88 mph. Their plan is successful, and upon reaching

20500-401: The past or future parallel time zones visited. Unlike the films, which took place entirely in Hill Valley and the surrounding area, the series frequently took the characters to exotic locations. At the end of every episode, Doc Brown would appear to do an experiment, often related to the episode's plot. The first season also included post-credits segments with Biff Tannen telling a joke related to

20664-446: The police station and is then arrested by Officer Parker for her crimes. Edna's DeLorean then vanishes because of the time ripples catching up with them, causing " chronal decay" (i.e., since Citizen Brown's timeline ceased to exist, the alternate Clone DeLorean was erased from existence). Marty and Doc return to 1986, where three DeLoreans (one normal, one blue, and one black) suddenly arrive with different versions of Marty. The duo leave

20828-401: The primary power source of the DeLorean's time travel, allowing the characters to bypass the arduous power-generation requirements upon which the plot of the first film hinges. The plutonium fission reactor was most likely left installed underneath Mr. Fusion as a backup power source. The Mr. Fusion can provide enough power to the flux capacitor and the time circuits, but is not used to power up

20992-429: The rear mirror being damaged, one of its windshield wipers being torn off, and the Mr. Fusion Reactor being knocked open (although Marty manages to close it). Once Marty finishes this task, he returns to Doc's DeLorean as they begin their return to 1931, activating the flux capacitor on Edna's DeLorean and making it speed up to 88 mph with its time circuits set to 1931. After they all return to 1931, Edna crashes in front of

21156-477: The run would have to be on a flat, straight track with no cars coupled behind it and with the boiler's temperature risen to dangerous levels. Doc replaces the 1955-style wheels with cast iron train wheels that fit on the track rails. Doc and Marty plan to make their run on a flat, straight section of track leading to an unfinished bridge over Shonash Ravine. While making their plans, Doc saves schoolteacher Clara Clayton from falling into Shonash Ravine. They realize in

21320-448: The same day as the climax of the first film, to give his past self a sports almanac which the young Biff uses to accumulate wealth from gambling. Biff returns the DeLorean to 2015, without Marty or Doc discovering his use of it until they return to 1985, which due to Biff's manipulation of history, has been transformed into a post-apocalyptic alternate timeline in which Biff is a wealthy casino boss and crime lord. Discovering from that this

21484-511: The second film, has been called " Back to the Future Day" by the media. The year 2015 also commemorated the 30th anniversary of the release of the original film. Many promotions were planned to mark the passing of the date, with many playing to the depiction of the future in the film, including: Cast members appeared on Today and Jimmy Kimmel Live! on October 21, 2015. Nearly 2,000 theaters worldwide showed back-to-back screenings of

21648-648: The setting for the film characters in Part II , the production was delayed following the August 2014 departure of director Jamie Lloyd , due to "creative differences" with Zemeckis. The show received its premiere at Manchester Opera House in February 2020 ahead of an expected West End transfer. The March 11, 2022, release of the original cast recording preceded a Broadway production that opened August 3, 2023. In 2015, Fox and Lloyd starred alongside popular YouTube science personality Go Tech Yourself in an extended Toyota commercial for Toyota's new fuel cell vehicle ,

21812-492: The starter, Marty is forced to run to the Twin Pines Mall, now called the Lone Pine Mall due to his actions in 1955. He is too late as Doc is gunned down while his other self escapes to 1955, leaving the Libyans to crash into a photo booth, but it is revealed that Doc wore a bulletproof vest and had listened to Marty's warning after all. After returning Marty home, Doc travels with Einstein to October 21, 2015, where he upgrades

21976-430: The sticky, flammable substance that causes chimney fires . Pellets burn very cleanly and create only a layer of fine ash as a byproduct of combustion. The grade of pellet fuel affects the performance and ash output. Premium-grade pellets produce less than one percent ash content, while standard or low grade pellets produce up to six percent ash. Pellet stove users should be aware of the extra maintenance required with

22140-436: The time circuits, a pair of vents on the back that heat the vehicle after it travels through time, a plutonium chamber that serves as its original power source before being replaced by Mr. Fusion, and a wormhole emitter on the roof that helps the car travel through time via wormholes. Doc had also built a special remote that can control the car, although it was only used once. After it ended up in 1955, Doc placed an alarm clock on

22304-465: The time circuits, but without the needed plutonium to return to 1985. Once there, the DeLorean exhibits problems with the starter, and with its plutonium chamber empty, Marty hides the DeLorean behind a road sign and contacts the Doc Brown living in 1955. The two bring it to Brown's workshop. Unable to obtain plutonium, Doc and Marty realize, from a fundraising flyer given to Marty earlier in the film, that

22468-459: The time machine from 2012; Doc Brown Saves the World! , a new short movie starring Christopher Lloyd; two episodes from The Animated Series ; two novelty commercials about "Jaws 19" and the "2015 Hoverboard"; and other additional features. A new set was released in October 2020 for The Ultimate Trilogy , to celebrate the franchise's 35th anniversary, and featured a release on Ultra HD Blu-ray for

22632-470: The time machine was added to the Library of Congress 's National Historic Vehicle Register. The control of the time machine is the same in all three films. The operator is seated inside the DeLorean (except the first time, when the remote control is used), and turns on the time circuits by turning a handle near the gear lever, activating a unit containing multiple fourteen- and seven-segment displays that show

22796-487: The time of filming. The appliance from which the prop was made was actually a Krups "Coffina" model coffee grinder. The Mr. Fusion Home Energy Reactor converts household waste to power for the time machine's flux capacitor and time circuits using nuclear fusion , presumably cold fusion . In the film, Mr. Fusion allows the DeLorean time machine to generate the required 1.21 gigawatts needed to travel to any point in time. The energy produced by Mr. Fusion replaces plutonium as

22960-406: The timeline. In several separate differing timelines, various altered outcomes are shown for the McFly family, and then separately for the entire Hill Valley region. At the conclusion of the game, the timeline is largely restored by Marty and Doc, although with some small differences from the "original" timeline. Two pinball adaptations of the film trilogy were released. The first pinball adaptation

23124-409: The touch. Along with convection air, an exhaust fan forces air from the firebox through special venting specifically made for pellet fuel. This cycle of circulation is an integral part of the combustion system as well, for the concentrated high temperature flame will quickly overheat the firebox. The possible problems associated with overheating are electrical component failure and flames traveling into

23288-564: The tracks and departs from 1985, ending the trilogy. Co-writer and director Robert Zemeckis, who holds the rights to the films in the franchise , has stated that he will block all attempts to remake or reboot the original film. Co-writer Bob Gale commented that he did not wish to see another film in the series without the Marty McFly character nor any other actor than Michael J. Fox playing him, while acknowledging that Fox's current health condition would make this impossible. He illustrated this at

23452-402: The tracks, and Marty barely manages to escape before the DeLorean is completely destroyed by a freight train. Later, Doc, Clara, and their children: Jules and Verne, appear in the same location where the DeLorean was destroyed, piloting a new time machine in the form of a steam-powered train. After picking up Einstein, the couple and their children depart for an unknown time period. In the films,

23616-602: The trilogy also received a novelization that expanded on the movies by adding scenes, characters, and dialog, often culled from early-draft scripts.
