153-525: The Tenth Planet is the partly missing second serial of the fourth season in the British science fiction television series Doctor Who , which was first broadcast in four weekly parts from 8 to 29 October 1966. It was William Hartnell 's last regular appearance as the First Doctor , and the first story to feature the process later termed " regeneration ", whereby the lead character, The Doctor , undergoes
306-461: A 16 mm telerecording copy of the original untransmitted pilot, presumably a viewing print made in 1963 and subsequently lodged at the Library. The Film Library also held high-quality original film sequences made for insertion into videotaped episodes. Some of these, such as those from Episodes 1–2 of The Daleks' Master Plan , survive to this day. Other junked sequences were mistakenly entered into
459-645: A Time Lord can regenerate twelve times (thirteen incarnations in all). There were exceptions to this rule, however: when the Master reached the end of his regenerative cycle, he took possession of the body of another person to continue living. In " The Five Doctors ", the Master was offered a new cycle of regenerations by the High Council to save the Doctor from the Death Zone, which may indicate that there are methods to circumvent
612-658: A Time Lord. This story element was notably featured in Series 3 ; the Doctor uses it to hide himself from the Family of Blood and becomes a schoolteacher in Edwardian England. His nemesis the Master used it to disguise himself as a human to escape the Time War. The story element is later revisited in the Series 12 episode " Fugitive of the Judoon " when a mysterious, unknown incarnation of
765-446: A crack in time to grant him a full new regeneration cycle. The revelation in 2020's The Timeless Children that The Doctor is, in fact, not Gallifreyan and instead had their DNA used to give Gallifreyans the ability to regenerate, calls into doubt whether or not the Doctor does in fact have a limit to their regenerations, or if they merely believed they did due to all other Time Lords being limited. The Time Lord homeworld, Gallifrey ,
918-452: A depiction of the ultimate outcome of biomechatronic and prosthetic technology in medical science. The writer John Kenneth Muir has noted that Pedler and Davis had previously written about dystopian scientific themes, and would later collaborate on Doomwatch , a speculative fiction BBC TV drama series. Muir suggests that the concept of the Cybermen may have been the inspiration behind
1071-656: A different concept of ageing from humans. In " The Stolen Earth ", the Tenth Doctor refers to when who he thought was his original incarnation was a "kid" at 90 years old. However, within a specific incarnation, a Time Lord is able to age, albeit much more slowly than a human. The War Doctor and Eleventh Doctor , over the course of the Last Great Time War and the Battle of Trenzalore , respectively, are seen to age within their respective incarnations to what would appear to
1224-581: A female. The Doctor also regenerated as a woman in " Twice Upon A Time ", as the Thirteenth Doctor . Whether or not Time Lords can recognise each other across regenerations is not made entirely clear: In " The Impossible Astronaut ", a future version of the Eleventh Doctor is shot, causing him to begin his regeneration cycle. He is shot again before the regeneration completes, causing him to die instantly. However, in " The Wedding of River Song ", it
1377-532: A few seconds leading up to it. The sequence had been shown in a 1973 episode of Blue Peter and was retained in that show's archive. Even after the end of the purge, other archive issues persist. Serials from Seasons 22–26 were shown in Germany, with soundtracks dubbed into the German language; some of these episodes no longer exist in German television archives. On 20 April 2006, it was announced on Blue Peter that

Following the establishment of the Film and Videotape Library, an audit of the Engineering Department found 60 of the 128 Third Doctor episodes starring Jon Pertwee , which in addition to the Film Library's copies of

An appeal to broadcasters in other countries who had shown the programme (notably Canada and African nations such as Nigeria ) produced "lost" episodes from the archives of their television companies.

While the master videotapes for Episodes 1 to 3 of Planet of Giants were wiped in January 1969, the fate of Episode 4's original studio recording tape is not known, though it is generally believed that all material not used in the combined final episode was junked. The serial's 2012 DVD release features

Also seen in " Journey's End ", is the apparent ability to siphon off regeneration energy in order to cancel the effect of changing appearance; which requires them to have a "bio-matching receptacle" (in this case the Doctor's severed hand), which is usually impractical. However, this "non-regeneration" was revealed as "counting" towards the Doctor's twelve possible regenerations during
2142-451: A hoax, the BBC produced a special introduction for an intended VHS release of the story, hosted by Michael Craze , two versions of which were filmed: one explaining that Episode 4 was still missing, the other introducing the story as if it were complete. A documentary called Missing in Action , made in 1993 and narrated by Nicholas Courtney , also mentions the hoax. In 2000, BBC Video released
2295-491: A human to be old age; both conflicts are suggested within the series to last hundreds if not thousands of Earth years. In The Two Doctors , the Second Doctor states that the "Rassilon Imprimatur" allows Time Lords to safely travel through time, becoming symbionts with their TARDISes, and that the reason other species are incapable of developing time travel is that they lack the imprimatur. However, he implies later that he
2448-636: A later popular science-fiction cyborg race, the Borg , which first featured in Star Trek: The Next Generation (" Q Who ") in 1989. The writer Kevin S. Decker has evaluated the role of the Cybermen introduced in The Tenth Planet in terms of the traditions of continental philosophy , and considers that they have been deliberately crafted by Davis and Pedler to symbolise the Others in opposition to
2601-582: A life-sized Dalek would be given to anyone who found and returned one of the missing episodes. In January 2007, ITV began a campaign called "Raiders of the Lost Archive" and although the campaign was run by ITV, they were also looking to find Doctor Who episodes and other BBC shows. One episode of the Raiders of the Lost Archive show aired in January 2007 and a further two episodes in July 2009. In December 2012,
2754-597: A limited number of times within a specific timeframe, and deliberately set the fees for further use so high that broadcasters would consider it unjustifiable to spend so much money repeating an old programme rather than making a new one. Consequently, recordings whose repeat rights had expired were considered to be of no further domestic use to the broadcasters. Most Doctor Who episodes were made on two-inch videotape for initial broadcast and then telerecorded onto 16 mm film by BBC Enterprises for further commercial use. Enterprises used 16 mm for overseas sales as it
2907-518: A metaphor for evil. Graham Sleight notes that The Tenth Planet was produced at a time when modern medicine was pioneering transplant surgery , lending a sense of topicality to Davis and Pedler's concept for malevolent cyborgs. He also finds contemporary significance with the 1960s rocket programmes, and notes that the multinational makeup of the Antarctic base crew is particularly noteworthy, having no precedent in earlier Doctor Who stories. However, he
3060-598: A new personality. Regenerations can be traumatic. In Castrovalva , the Fifth Doctor requires the use of a Zero Room, a chamber shielded from the outside universe that provides an area of calm for him to recuperate. The Time Lord's personality also sometimes goes through a period of instability following a regeneration, such as in The Christmas Invasion . It was first stated in The Deadly Assassin that
3213-476: A powerful and wise race from the planet Gallifrey , from which the Doctor was a renegade; details beyond this were very limited for the first decade of the series. They later became integral to many episodes and stories as their role in the universe developed. For the first eight years after the series resumed in 2005, the Time Lords were said to have been destroyed during the Last Great Time War at some point in

In The Time Warrior (1973–1974), the name of the Doctor's home planet, Gallifrey , was revealed on screen for the first time. The Time Lords are considered one of the oldest and most technologically powerful races in
3519-450: A race who, though once like human beings, have gradually replaced their bodies with mechanical parts, and eliminated the "weakness" of emotion from their brains . The Cybermen prevent the base staff from saving the Zeus IV , and it is destroyed by the gravitational pull of Mondas. The emotionless Cybermen state that the lives of the crew are irrelevant to them. The Cybermen explain that Mondas
3672-516: A reconstruction of the original episodes, directed by Ian Levine. The production rebuilds the deleted scenes using CGI, footage from elsewhere in the serial, and re-recorded dialogue from Carole Ann Ford , William Russell , and actors impersonating the rest of the cast. When the BBC's complete holdings (both the BBC Film & Videotape Library and the BBC Enterprises ) were first audited in 1978,
3825-618: A routine probe on the Earth 's atmosphere. The spaceship is drawn off-course by an unknown force, and Snowcap monitoring staff discover a new, unknown planet approaching Earth. Recognising identical landmasses to those of Earth, the Doctor reveals it is Mondas , the Earth's long-lost twin planet, and that its inhabitants will soon be visiting Earth. A mysterious spaceship lands in the snow and three robotic creatures emerge, kill guards and infiltrate Snowcap Base, taking control. They reveal they are Cybermen ,
3978-447: A special feature on the DVD releases for The Three Doctors and Castrovalva . The story was individually released on DVD on 14 October 2013, with the missing fourth episode animated along with additional extra features, including the original reconstruction of episode four from the 2000 VHS release, and a special documentary, Frozen Out , on the making of the story.

The Doctor became at times an ally, being appointed their president during his fourth , fifth , and twelfth incarnations and assisting them on many other occasions. In an audio commentary recorded for the 2009 DVD release of The War Games (1969), producer Derrick Sherwin mentioned how in a discussion with
4437-451: A transformation into a new physical form. Patrick Troughton makes his first, uncredited appearance as the Second Doctor . The serial is also notable as the first story to feature the Cybermen , a race of malevolent cyborgs that became a recurring adversary in later Doctor Who stories. The "tenth planet" in the title makes reference to a fictional lost planet in Earth's Solar System ; at
4590-457: A trial is a "very rare" event for the Time Lords. Exceptions to this policy are made only in extreme circumstances when they feel they have to, such as where the Doctor calls them for help in the serial. At the start of the 2005 television series, Gallifrey was thought to have been destroyed and the Time Lords functionally extinct as a result of a mutually destructive Time War with the Dalek race;

In order of original transmissions, the very last Doctor Who master videotapes to be wiped were the first episodes of the 1974 serials Invasion of the Dinosaurs and Death to the Daleks .

As such, it is included in a list of the twenty most wanted missing programmes (as drawn up by the British National Film Theatre ) alongside the BBC studio footage from the Apollo 11 landings (which is currently held only in soundtrack form).

The points in time when Gallifrey appears are never definitively stated. As the planet is often reached by means of time travel, its relative present could conceivably exist almost anywhere in the Earth's past or future, as well as anywhere in the conceivable universe. From space, Gallifrey
5661-417: Is disappointed by the overall execution of The Tenth Planet serial, finding the Cybermen "dull, stereotyped villains" and the portrayal of the Antarctic base staff dependent on "national stereotypes". The introduction of the concept of regeneration in The Tenth Planet is noted as a landmark in the show's history, and it has been credited with establishing the longevity of the television series by ensuring
5814-639: Is not unique in its losses, as many broadcasters routinely cleared their archives in this manner. Until the BBC changed its archiving policy in 1978, thousands of hours of programming in all genres were deleted. Other affected BBC series include Hancock's Half Hour , Dad's Army , Z-Cars , The Likely Lads , The Wednesday Play , Till Death Us Do Part , Steptoe and Son , Dixon of Dock Green and Not Only... But Also . ITV regional franchisees, such as Rediffusion Television and Associated Television , also deleted many programmes, including early videotaped episodes of The Avengers . Doctor Who

The Eleventh Doctor slightly amends what was said earlier in " The Doctor's Wife ", saying that he could only sense if there were other Time Lords in this universe. In the original series episode Warriors' Gate , Romana is called a 'time-sensitive' by a marauding slaver and, though she seems to deny this,
6579-453: Is speculated by Donna Noble in " The Doctor's Daughter " (2008) to be a surviving Time Lord, though the Doctor initially rejects the suggestion. Two other Time Lord-like beings appeared in " Journey's End " (2008): Donna, briefly empowered with the mind and knowledge of a Time Lord, and a half-human clone of the Tenth Doctor. Donna's memories related to the Doctor, as well as her Time Lord knowledge, are buried in order to save her life, while

In Death of the Doctor , the Eleventh Doctor responds to a question from Clyde Langer by saying he can regenerate "507" times.

Most episodes are also represented by production stills, tele-snaps , or short video clips. Furthermore, after careful restoration, all 1970s episodes are available in full colour. Efforts to locate the missing episodes have continued, both by the BBC and by fans of the series. The recovered episodes have been extensively restored for release on VHS and DVD ; surviving soundtracks have been released on cassette and compact disc . Many missing episodes have had their visuals reconstructed, either through specially commissioned animation or use of surviving footage and photographs. Between approximately 1967 and 1978, large quantities of videotape and film stored in

He is also able to concentrate and time his motions well enough to step safely through the blades of a rapidly spinning fan, and later claims that if any Time Lords still existed, he would be able to sense them. As the Tenth Doctor he repeats this assertion, adding also that he
7344-507: The BBC . Between 1967 and 1978, the BBC routinely deleted archive programmes for various practical reasons—lack of space, scarcity of materials, and a lack of rebroadcast rights. As a result, 97 of 253 episodes from the programme's first six years are currently missing, primarily from seasons 3 , 4 and 5 , leaving 26 serials incomplete. Many more were considered lost until recovered from various sources, mostly overseas broadcasters. Doctor Who

In " Rise of the Cybermen " (2006), the Tenth Doctor mentions, "When the Time Lords kept their eye on everything, you could pop between realities , home in time for tea. Then they died, and took it all with them. Walls of reality closed,

11475-477: The Doctor spends centuries believing he burnt Gallifrey until the Eleventh Doctor's time; this is because the time streams are out of sync after the War Doctor meets his future selves and the altered events are only known to the Doctor once they occur in the Eleventh Doctor's experience and become part of his memory. Indeed, earlier on in the episode, both the Tenth and the Eleventh Doctors mistakenly believe that
11628-426: The Doctor there to begin with for questioning—and exile him in "Hell Bent" before running off again. Time Lords and human beings look alike, however they differ in many respects. Physiological differences from humans include two hearts which normally beat at 170 beats per minute, and a "respiratory bypass system" that allows them to survive strangulation. The Twelfth Doctor was able to survive direct exposure to
11781-404: The Doctor would be in trouble. In a 2016 interview with The Essential Doctor Who magazine, Dicks mentioned how when Sherwin and he were discussing The War Games one day, Sherwin said, "He belongs to this mysterious race called the Time Lords, doesn't he?" with "everything" ultimately coming from that discussion. In The War Games DVD commentary, Sherwin mentioned that he recalled hearing about
11934-450: The Doctor", he works together with them to change the assumed outcome of the Time War : thirteen incarnations of the Doctor team up together to freeze Gallifrey in time and place it outside of their universe (protecting it and the remaining Time Lords), while the Daleks destroy themselves in their own crossfire once Gallifrey is gone. The War Doctor does not retain the memory of these events and
12087-476: The Doctor's, Madame Vastra , reminds the Doctor that the Time Lord race developed due to their billions of years' exposure to the time vortex. The Doctor then recalls that Rory and Amy had spent their wedding night in the TARDIS; therefore it is theorised by Vastra that River's conception mirrored that of the Time Lords' genesis and therefore she herself developed Time Lord genetic characteristics. In " The Night of
12240-541: The Engineering Department continued into the 1970s. Eventually, every master videotape of the programme's first 253 episodes (1963–69) was destroyed or wiped. The final 1960s master tapes to be erased were those for the 1968 serial Fury from the Deep , in August 1974. Despite the destruction of these masters, BBC Enterprises held an almost complete archive (with the possible exception of one episode of The Daleks' Master Plan ) of
12393-568: The Master uses the same technique, allowing the Tenth Doctor to hear the drumming sound the Master constantly hears. The Doctor later displays his telepathic communion powers in " Fear Her " and in " The Shakespeare Code ", where by using his mind melding technique he is partially able to relieve a man of his mental illness as he traces back through his memories. In " Planet of the Ood ", the Tenth Doctor seems able to temporarily confer some degree of telepathy on his companion Donna Noble, so that she can hear
12546-526: The Master's laser screwdriver, and telekinetically disarm the Master. In addition, Time Lords may be clairvoyant , or have additional time-related senses. In The Time Monster , and Invasion of the Dinosaurs , the Third Doctor is able to resist fields of slow time, being able to move through them even though others are paralysed . In City of Death , both the Fourth Doctor and Romana notice distortions and jumps in time that no one else does. In
12699-631: The Restoration Team who is also a missing episode hunter) said in a podcast interview that "there is absolutely no question" that some missing episodes are held by private collectors, including "one or two" by collectors that he knows. In August 2020, he described how a copy of The Daleks' Master Plan may have survived in Australia. He reiterated in March 2021 that missing Doctor Who episodes do exist out there. In April 2020, Philip Morris repeated that
12852-529: The Tenth Doctor as being capable of surviving (for a short period) a massive burst of radiation that would have killed anything else instantly. However, the radiation burst caused enough damage to start a regeneration. Time Lords are extremely long-lived, routinely counting their ages in terms of centuries; the Second Doctor claimed in The War Games that Time Lords could live "practically forever, barring accidents". The series has suggested that Time Lords have
13005-453: The Tenth Doctor explains to Wilfred Mott that a Time Lord can die before they have a chance to regenerate, in which case they die outright. In The Deadly Assassin at least one of the murders was carried out with a 'staser', possibly a weapon designed to both kill and prevent regeneration (stasers are also stated to have little effect on non-living tissue). In the Series 4 episode " Turn Left ",
13158-423: The Tenth Doctor's body is shown on a stretcher following the parallel events of " The Runaway Bride ". A UNIT officer states that the Doctor's death must have been too quick to allow for regeneration. In Destiny of the Daleks , Romana showed the ability to rapidly change form several times in a row during her first regeneration, and apparently had the ability to change into whatever appearance she desired. When
13311-411: The Time Lords are attempting to return to the universe and will come back if he speaks his true name. Due to "half the universe" surrounding Trenzalore, a siege begins that lasts centuries as the Doctor knows that if the Time Lords return, the Time War will begin anew. With the Doctor on the verge of death, Clara Oswald pleads with the Time Lords through the crack to intervene and save the Doctor. Through
13464-516: The Time Lords at the beginning of the series, but as no one else remembered this, it "might have come out of [his] dreams". Elaborating on this genesis in a 2014 interview in Doctor Who Magazine , Sherwin said of The War Games , "It was a case of what shall we do, how can we end this? Let's go back to the beginning and say [the Doctor] was a Time Lord, a renegade Time Lord, a pain in the arse for
13617-409: The Time Lords have the ability to grant more regenerations: at the behest of Clara Oswald they granted the Doctor himself a new cycle when he was at the point of death from old age, having used up his entire cycle. Regeneration, regardless of how many regenerations the individual Time Lord has already undergone, is a conditional and non-inevitable phenomenon. This is stated in " The End of Time " when
13770-465: The Time War. During the episode "The Doctor's Wife" it is revealed that several Time Lords and their TARDISes had been trapped and destroyed by an entity called House who lived in a separate bubble universe. In " A Good Man Goes to War " (2011), it is revealed that the daughter of Amy Pond and Rory Williams , Melody Pond (who later goes by her transliterated name " River Song "), has been born with Time Lord-like genetic traits. An old acquaintance of
13923-442: The War Doctor killed all of the Time Lords on the last day of the Time War. After being informed that the plan to save Gallifrey was successful, the Eleventh Doctor sets out to find Gallifrey and restore the Time Lords. In " The Time of the Doctor ", the Doctor visits the planet Trenzalore where he discovers a question being broadcast through all of time and space through a crack in the universe: "Doctor Who?" The Doctor realizes that
14076-478: The ability to stay conscious for moments after events that would outright kill other lifeforms instantly, giving them the opportunity to regenerate. This is seen in Logopolis (fall from a great height), and The Caves of Androzani (fatal disease). In both " The Stolen Earth " and " The Big Bang ", the Doctor is shot by a Dalek's energy weapon, which has almost always been shown to instantly kill any other lifeform, yet
14229-452: The actors and writers to sell the programmes abroad had expired. With many broadcasters around the world now switching to colour transmission, it was not deemed worthwhile extending agreements to sell the older black-and-white material. The BBC Film Library, meanwhile, had no responsibility for storing programmes that had not originated on film, and there were conflicting views between the Film Library and BBC Enterprises over which party held
14382-502: The base to announce that the Cyberman threat has ended. Ben frees the Doctor and Polly from the Cybermen's spaceship. The Doctor, seemingly ill, says “it’s far from being all over” and abruptly leaves for the TARDIS. Ben and Polly find the TARDIS and urge to be let in; though weak, the Doctor gathers enough energy to let Polly and Ben in. The Doctor falls unconscious and transforms into a younger man . All four episodes of this story feature
14535-464: The character of Cutler and Hartnell's Doctor. Den of Geek named the cliffhanger of Episode 4 as one of the programme's ten "classic" cliffhangers. Alasdair Wilkins of io9 described it as "a very solid, at times excellent story" and noted "The Cybermen have possibly been more intimidating in other stories, but they have never been creepier than they are here". He named it the fourth best regeneration and regeneration story. DVD Talk 's John Sinnott gave
14688-467: The children's programme Blue Peter in 1973 when they wished to use a clip from it in a feature on the tenth anniversary of Doctor Who . Although a print of The Daleks' Master Plan Episode 4 ("The Traitors") was loaned to Blue Peter and not returned to the BBC Film Library, there was never a copy of The Tenth Planet Episode 4 there to have been loaned. Another department – BBC Enterprises –
14841-405: The clone lives out his existence in a parallel universe with Rose Tyler . " The End of Time " (2009–10) shows the High Council of Time Lords, led by Lord President Rassilon , attempting to escape the Time War by materialising Gallifrey in the place of Earth at Christmas. However, the Tenth Doctor destroys the device which allows their passage into the present, sending them back into the events of
14994-525: The collection, Malden turned her inquiries to the National Film and Television Archive – which promptly returned three full Second Doctor serials – The Dominators , The Krotons , and The War Games , adding seven more episodes and completing two of those serials. These all were standard 16 mm film telerecordings with the exception of The Dominators Episode 3, which was a 35 mm print. Episodes 4 and 5 of The Dominators originated from
15147-463: The crack, the Time Lords grant the Doctor a new regeneration cycle, saving his life before sealing the crack again. In " Hell Bent " (2015), it is revealed that Gallifrey returned to the universe around the time of its end. After escaping his confession dial in " Heaven Sent " (2015), still furious over the death of Clara Oswald in " Face the Raven " (2015), the Doctor manages to depose Rassilon—who had put
15300-525: The events of " The Time of the Doctor ". In "The End of Time", the Tenth Doctor was able to postpone his regeneration long enough so that he could travel in time and space to see his past companions for one last time before he regenerated. The Fifth Doctor had also shown a similar ability in The Caves of Androzani , fighting off the effects of an impending regeneration so he can return to Androzani Minor to save his companion Peri. Time Lords appear to have
15453-572: The film-originated Spearhead from Space , brought that Doctor's episode count up to 64 out of 128. In 1978, Ian Levine located another 65 episodes from the show's first six seasons (plus 14 previously existing episodes), at the BBC Enterprises film vault at Villiers House in London. The episodes comprise 17 full serials, mostly from seasons 1 and 2. According to Levine, the prints of The Daleks were flagged to be junked that very day. Levine alerted
15606-456: The film-originated episodes of Doctor Who ( The Power of the Daleks Episode 6 and The Wheel in Space Episode 5) were junked by the Film Library, while it held such unexplained material as 16 mm copies of The Tenth Planet Episodes 1–3, presumably viewing prints which were mistakenly returned to them at some point instead of BBC Enterprises. Most surprisingly of all, they also retained
15759-526: The first Doctor, and one including the Daleks (hinting that it could be a missing episode of The Daleks' Master Plan ), but the owners were reluctant to return them to the BBC. He recommended that the BBC implement measures to ensure that those possessing copies of missing episodes would neither have their collections confiscated nor be prosecuted for possessing BBC property, arguing that such protections would encourage more collectors to come forward with salvaged telerecordings. However, Franklin later responded to
15912-455: The following episodes were absent from their collective archives, but have subsequently been returned to the Corporation through various methods. The 16 stories highlighted have all episodes existing as a result. Except where indicated, all episodes were returned as 16 mm telerecording negatives or prints. Note: Except for Invasion of the Dinosaurs and Death to
16065-507: The galaxy". In the very distant past, the Time Lords fought a genocidal war against the Great Vampires, which led to such a catastrophic loss of life that the Time Lords renounced violence. In The War Games , the Second Doctor mentions that the Time Lords' "great powers" are hardly ever used due to their policy of non-intervention into the affairs of other planets, and that they instead observe and gather knowledge. Because of this, holding
16218-629: The gaps are from seasons 3, 4, and 5, which currently lack a total of 79 episodes across 21 (out of 26) serials. By contrast, seasons 1, 2, and 6 are missing just 18 episodes, across 5 (out of 26) serials. Of these missing stories, all but three – Marco Polo , " Mission to the Unknown ", and The Massacre of St Bartholomew's Eve – have surviving clips. All episodes also have full surviving audio tracks. As of September 2022 , many of these missing serials have been officially "completed" by using animation and/or telesnap reconstruction, and then subsequently released commercially by BBC Worldwide . While
16371-411: The help of Polly and Barclay, sabotages the Z-bomb rocket. Cutler attempts to fire the Z-bomb, but the engines fail on the launchpad. As Cutler threatens to kill Ben, Barclay, and the Doctor, who has regained consciousness, he is killed by a new squadron of Cybermen. The Doctor, who informs Polly his body is “wearing a bit thin”, and realising that Mondas is approaching destruction, attempts to mediate with
16524-445: The human race. Decker states that this sense of Otherness is achieved by Pedler's focus on the theme of "dehumanising medicine" by presenting a race of humans who have replaced most of their flesh and organs with cybernetic parts. Decker also observes that The Tenth Planet plot is based on the "base under siege" scenario, a popular science-fiction device that has been reused in many subsequent Doctor Who stories, and that this serves as
16677-481: The line was not intended to be taken seriously and is instead a commentary. He said that the "thirteen lives" rule was too deeply entrenched in the viewer consciousness for his throwaway line to affect it. It is revealed in " The Time of the Doctor " that this was in fact false and that due to his various regenerations, the Eleventh Doctor was in fact his last incarnation. However, the Time Lords intervened through
16830-411: The memories of her travels in the TARDIS and to 'implant' a defence mechanism which is activated in " The End of Time ". The War Games showed that other Time Lords are also able to erase people's memories, as in that story, Jamie and Zoe 's travels with the Doctor were erased from their memory, and the council of Time Lords also put a memory block on the Doctor so he could not pilot the TARDIS. In
16983-536: The missing Doctor Who episodes are probably the best-known example of how the lack of a consistent programme archiving policy risks permanent loss. Following the purges and subsequent recoveries, gaps in the Doctor Who archive are spread unevenly through its first 11 seasons. Major losses mostly affect First and Second Doctor serials; although two stories are missing just one episode each ( The Tenth Planet , Episode 4 and The Web of Fear Episode 3), other stories are lost altogether. Patrick Troughton 's era as
17136-512: The missing episodes bridged using animation, visual reconstructions, or narration to the camera. Surviving episodes which form 50% or less of a complete story – referred to as "orphaned" episodes – have been released by the BBC in compilations (e.g., Lost in Time ), or as extras on releases of complete serials. A few four-episode serials of which 50% remain (e.g., The Underwater Menace , The Moonbase ) have also been issued as standalone releases. In 2023, all Doctor Who episodes in
17289-471: The most widely sold abroad of the 1960s era, are missing only nine and two episodes, respectively. By contrast, the less well-sold Season 4 has no complete serials, while Season 5 has only two complete serials ( The Tomb of the Cybermen and The Enemy of the World ). Doctor Who ' s high profile has also helped to ensure the return of episodes which, for other less well-remembered programmes, might never have occurred. Of all ongoing BBC series from
17442-403: The new Film and Videotape Library's archive selector, Sue Malden, who paid her own visit to Villiers House and found every remaining Jon Pertwee episode (albeit as a 16 mm black-and-white telerecording), except for two from his final season: Death to the Daleks and Invasion of the Dinosaurs , Episodes 1. In August 1988, 10 years after Levine's and Malden's visits, Episodes 1 and 4–6 of
17595-430: The newly animated fourth episode, is also contained on the "Regenerations" box set, released on 24 June 2013. The soundtracks for The Tenth Planet and The Invasion , put together from fan-made recordings, along with a bonus disc, The Origins of the Cybermen , an audio essay by Cyberman actor David Banks , were released on CD in a collector's tin called Doctor Who: Cybermen . A CD of stock music used in this serial
17748-414: The nine episodes that had originally been telerecorded onto film for editing and/or transmission, rather than recorded to videotape. These film-originated masters were stored in the Film Library, rather than in the Engineering Department with the videotapes. The presence of the viewing prints is less easily explained. The Film Library's remit covers material originated on film, not on videotape – yet two of
17901-462: The original script, but places the action in the year 2000 rather than 1986, as well as restoring the Doctor to the third episode. Also, in the first scene in which the Doctor, Ben and Polly appear (in the TARDIS), the Doctor is beginning to show signs of his failing health; sometimes mistakenly addressing Ben and Polly as " Ian " and " Barbara ", thereby revealing signs that all is not as it should be. Also,
18054-399: The orphaned episode was also animated. In addition to the official list of missing episodes, also missing is the original Episode 1 of The Daleks . At some point after the recording, it was discovered that a technical problem had caused backstage voices to be heard on the resulting videotape; in early December 1963, the episode was remounted with a different costume for Susan. This episode
18207-439: The other Time Lords who stole his TARDIS and buggered off around the universe. So if he's going to be called to book let's bring in the Time Lords." Early on in the series, the Doctor was identified as a human being; however, his home planet, which from the start of the series is explicitly established as not being Earth , was not named. In The War Games (1969), the Doctor's people appeared, who from then on are known as
18360-520: The production team, they took the opportunity to create "an elegant, inspired solution to a casting problem" that has endured in the programme's folklore. A novelisation of this serial, written by Gerry Davis , was published by Target Books in February 1976. It was the first Hartnell-era serial novelisation to be commissioned by Target, and the first new adaptation of a Hartnell adventure to be published in nearly ten years. The novelisation largely follows
18513-451: The programme videotapes they held, although typically they would not be wiped or junked until the relevant production department or BBC Enterprises indicated that they had no further use for the tapes. The first Doctor Who master videotapes to be wiped were those for the serial The Highlanders , which were erased on 9 March 1967, a mere two months after Episode 4's original transmission. Further erasing of Doctor Who master videotapes by
18666-466: The reason the Cybermen send humans to do this work is that the Cybermen are highly susceptible to radiation. Using radioactive rods from the reactor chamber as a weapon against the Cybermen, Ben and the crew regain control of the base. Just as more Cybermen enter the Tracking Room, Mondas explodes. Disconnected from their power source on Mondas, all the remaining Cybermen die. Geneva Space Command contacts
18819-599: The regeneration of the Doctor occurs in the TARDIS differently. The Doctor uses what appears to be a rejuvenation chamber that assists him in his regeneration. The story was released on VHS in the UK in 2000 from BBC Video, with the fourth episode reconstructed by the Doctor Who Restoration Team using still photos, existing clips and the surviving audio soundtrack. This release was a double-tape set entitled "Doctor Who: The Cybermen Box Set: The Tenth Planet and Attack of
18972-510: The regeneration sequence, have been discovered intact. In 2013, The Tenth Planet was released on DVD with a full-length animated reconstruction of its missing footage . The TARDIS lands at the South Pole in 1986, and the Doctor , Ben and Polly are taken to the Snowcap Base, a space tracking station commanded by General Cutler, supervising the mission of the Zeus IV spaceship, running
19125-545: The remaining missing episode of The Web of Fear was stolen, and claimed that "at least six" missing episodes are currently in the hands of private collectors, but they are uncertain how they would be treated if they returned the episodes to the BBC. Morris later tweeted that a blog claiming he was negotiating with these collectors was "completely false and fake". In November 2023, film collector John Franklin repeated Vanezis' claims to The Observer , which reported that two more missing episodes had been found, both featuring
19278-406: The responsibility for archiving programmes. As each body believed it the other's responsibility to archive the material, each thought nothing of destroying its own copies as necessary. This lack of communication contributed to the erasure of much of the Corporation's film archive of older black-and-white programming. While thousands of other programmes have been destroyed in this way around the world,
19431-650: The scanners being programmed to "detox" humans and therefore being unaware of what elements the Doctor requires. A Time Lord is able to conceal their Time Lord nature, and become a human, by using the Chameleon Arch – a device that stores their "essence" and memories in an innocuous device such as a fob watch , and replaces them with false counterparts until the object is later re-opened. The process allows them to disguise themselves as humans physiologically and psychologically, meaning they only have one heart and are stripped of non-human powers, and of any memory of having been
19584-444: The script by Martinus suggested that the Doctor was refusing to give in to the regeneration process. In 2017, Doctor Who writer Steven Moffat exploited this idea and created an extended narrative around the Doctor delaying his regeneration for the episode " Twice Upon a Time ". The episode uses original footage from The Tenth Planet alongside new scenes with David Bradley portraying the First Doctor, encountering his future self,
19737-449: The serial's co-writer Terrance Dicks the previous day, Dicks was "absolutely certain" that Sherwin created the Time Lords for the serial, although Sherwin could not remember himself. Later in the commentary, Dicks recalled Sherwin telling him in the discussions with Dicks and Dicks' fellow co-writer Malcolm Hulke that because the Doctor had always been established as being on the run from his own people, that if he has to appeal to them,
19890-510: The series in the form of their 16 mm film telerecording copies until approximately 1972. From around 1972 to 1978, BBC Enterprises also disposed of much of their older material, including many episodes of Doctor Who. The final 1960s telerecordings to be junked were those for the 1966 serial The War Machines , in early 1978, shortly before the junking of material was halted by the intervention of fan Ian Levine . Enterprises' episodes were usually junked because their rights agreements with
20043-446: The shot from off-air video copies. Internally, the wiping policy officially came to an end in 1978, when the means to further exploit programmes by taking advantage of the new market for home videocassette recordings started to become apparent. The prevailing view had also begun to shift toward the attitude that archive programmes should, in any case, be preserved for posterity and historical and cultural reasons. The BBC Film Library
20196-522: The show's continuity between the television movie in 1996 and the show's revival. In 2013, the 50th anniversary special " The Day of the Doctor " concerned this supposed destruction and their eventual survival. They developed a culture of custodianship and time-related technologies based on this perception which includes strictly controlled space /time travel machines (known as " TARDISes ") and monitoring devices to travel through time and to prevent time from being subverted or abused—although actual action
20349-436: The six-part story The Ice Warriors were discovered in a cupboard at Villiers House when the Corporation was in the process of moving out of the building. Shortly after the junking process was halted and the BBC established its Film and Videotape Library for the purpose of storage and preservation, archive selector Sue Malden began to audit what material remained in the BBC's stores. When investigations revealed large gaps in
20502-459: The story four and a half out of five stars. He praised Hartnell's performance and the Cybermen. Ian Berriman of SFX was more mixed, giving the serial three out of five stars. He praised the Cybermen and the "palpable tension", but felt that the regeneration was tacked on and not enough background was given to make Mondas believable. The Cybermen were conceived for The Tenth Planet by scientist and writer Kit Pedler and screenwriter Gerry Davis as
20655-485: The story on VHS , with episode four reconstructed by the Doctor Who Restoration Team using still photos, existing clips and the surviving audio soundtrack. For the 2013 DVD release, episode 4 was animated by Planet 55 Studios. ^† Episode is missing In 2009, Patrick Mulkern of Radio Times found the original Cybermen design like "usherettes from some kinky, futuristic moviehouse", but praised
20808-402: The survival of the character of The Doctor. Accounts differ as to the reason for Hartnell's departure from the programme; the actor's poor health is often cited, while other claims state that he was dissatisfied with the increasingly "adult" nature of the programme's scripts. Regardless of Hartnell's reasons to quit, Muir notes that while Hartnell's departure initially created a serious problem for
20961-473: The telepathic song of the Ood. When she is unable to bear the song, the Doctor removes the ability. In " The Lodger ", the Eleventh Doctor (pressed for time and needing to convey a great deal of information to someone) smashed his forehead into another person's forehead, causing a massive instantaneous transfer of information. The Doctor also contacts the Time Lords by going into a trance and creating an assembling box in The War Games . In The Two Doctors ,
21114-616: The third episode. On the Monday before the programme was due to be recorded, he sent a telegram to the production team informing them that he was too ill to work. Gerry Davis rewrote the script to explain the Doctor's absence (his sudden collapse) and gave his dialogue to other characters, most noticeably Ben. This was not as much of an interruption to the episode's production as it would seem, as all four episodes had been written so that Hartnell would have relatively little to do in case of just such an event. The original draft of episode 4 did not feature
21267-526: The time of production, the Solar System was generally held to consist of nine planets, prior to the redesignation of Pluto as a minor planet . The Tenth Planet is an incomplete Doctor Who serial – one of many serials that were affected by the BBC 's policy of wiping archived programmes in the 1960s and 1970s. Only three of the four episodes are currently held in the BBC archives; the last episode remains missing, although several short clips, including
21420-503: The twelve regeneration limit. The Master says in " The Sound of Drums " that the Time Lords "resurrected" him to fight in the Time War . It was revealed in The Brain of Morbius that the Time Lords also use the Elixir of Life in extreme cases, where regeneration is not possible. It is confirmed in " The Time of the Doctor " that a Time Lord can normally regenerate only twelve times but that
21573-495: The vacuum of space in " Oxygen ". Time Lords also seem to have an increased resilience to higher frequencies of sound, as seen in " The Christmas Invasion " and " Partners in Crime ". If severely injured, Time Lords can go into a healing coma which lowers their body temperature to below freezing which the Doctor did in Planet of the Daleks . In the serial Destiny of the Daleks , Romana
21726-473: The world, and contacts Space Command HQ in Geneva . The chief scientist Dr. Barclay expresses concerns that the radiation caused by the exploding planet would cause immense loss of life on Earth, and Ben argues that Mondas might destroy itself anyway when it absorbs too much energy. Suddenly, the Doctor passes out. Faced with dissent, Cutler orders Ben to be imprisoned in a cabin with the Doctor. Ben escapes and, with
21879-551: The worlds were sealed. Everything became that bit less kind." In " The Satan Pit " (2006), the Tenth Doctor states that his people "practically invented black holes. Well, in fact, they did." Both the Beast (in "The Satan Pit") and the Doctor (in "The Sound of Drums" and " The Doctor's Wife ", 2011) believe the Doctor ended the War by killing all of the Time Lords and many of the Daleks. The Tenth Doctor's artificially created "daughter" Jenny
22032-429: Was "focusing on a dress size", but subsequently weighed herself, seeming unsure of how her new body had truly developed. The Doctor said on several occasions he wished he was "ginger", which he has seemed unable to control in previous regenerations. In " Last of the Time Lords ", when the Master is fatally wounded, he chooses not to regenerate, essentially committing suicide rather than regenerate and be kept prisoner by
22185-519: Was able to voluntarily stop both of her hearts beating, to fool the Daleks into believing that she was dead. The Doctor also shows a greater tolerance to cold compared to humans in The Seeds of Doom and " Planet of the Ood " and even Romana in The Ribos Operation , and in " 42 ", the Tenth Doctor states he is able to survive at absolute zero for a short period of time. In " World War Three ",
22338-700: Was considerably cheaper to buy and easier to transport than videotape. It also circumvented the problem of different countries' incompatible video standards, as film was a universal medium whereas videotape was not. The BBC had no central archive at the time; the Film Library kept programmes that had been made on film , while the Engineering Department was responsible for storing videotapes. BBC Enterprises only kept copies of programmes that they deemed commercially valuable. They had little dedicated storage space, and tended to place piles of film canisters wherever they could find space for them at their Villiers House property. The Engineering Department had no mandate to archive
22491-412: Was described as rare in practice due to their traditional policy of strict non-interference and neutrality.
