Archive Status: The first three episodes of this story exist as 16mm telerecordings, all held by the Film & TV Library when audited in 1978. The master tape of episode 4 was lent to the production team for the series "Junior Points of View" in 1966; other copies of this episode were destroyed by 1976. Only the regeneration sequence remained, as borrowed for a spot on the "Blue Peter" series, though about 78 seconds of 8mm footage taped off air by a fan's film camera exists. Telesnaps (off-air camera photographs) from this story exist in both the BBC archives as well as the hands of private collectors. Episode 4 was originally thought discovered in 1992 when a fan claimed to have found it, though this was later established to have been a hoax. The extant footage from episode 4 (from both the 1996 Australian censor clips as well as off-air 8mm recordings) runs as follows:

The TARDIS materialises in December 1986 at the entrance to a South Pole Space Tracking Station under the command of General Cutler (Robert Beatty). The scientists there are experiencing problems in controlling the return to Earth of a manned space capsule, and the Doctor realises that this is due to the gravitational pull of another planet which has entered the solar system and is now heading for Earth. His prediction is borne out when the base is invaded by a force of alien Cybermen (Gregg Palmer, Reg Whitehead, Harry Brooks, Bruce Wells, John Haines, John Slater, John Knott; voiced by Roy Skelton, Peter Hawkins).

The Cybermen's world, Mondas, is draining energy from the Earth, and the situation will soon become critical. Although Ben and Cutler manage to destroy the first wave of attackers, the base is then overrun by a second. However, one of the scientists, Barclay (David Dodimead), suddenly realises that the invaders are susceptible to radioactivity, and this suggests a means of fighting back. Using hand-held uranium rods, Ben and a group of the scientists are able to hold off and kill a number of Cybermen. At the story's climax, Mondas disintegrates due to absorbing too much energy, and all the remaining Cybermen collapse and die, having been totally dependent on their planet.

The Doctor has become steadily weaker during the course of the adventure, and after the defeat of the Cybermen he hurries back to the TARDIS. Polly and Ben follow, and find him collapsed on the floor of the control room. As they watch, his face is transformed into that of a much younger, dark-haired man (Patrick Troughton).

Story Notes
The final story of the William Hartnell era, famous for introducing two long-running concepts to the program: the villainous Cybermen, and the concept of renewal (later known as regeneration). Writers Pedler and Davis are referred to as "Kitt Pedler" and "Gerry Davies," erroneously, on episodes 1 and 3, respectively. William Hartnell was ill and did not appear in episode 3; however, because of the nature of the story (the Doctor's illness implying death forthcoming), this did not require much rewriting. Michael Craze met his wife on this story, a production assistant. Patrick Troughton was uncredited in this story, appearing only at the end, unconscious.

DVD release
The existing video footage of the regeneration sequence from episode 4 is included on the "Lost in Time" DVD set released in 2004 as "The Tenth Planet: Surviving Clips" option. The the 8mm off-air home movie clips from episode 4 are included as part of the "8mm Footage" option.
Video release
Released as "The Cybermen Box Set: The Tenth Planet and Attack of the Cybermen" double-tape set in the UK [November 2000] and Australia/New Zealand [November 2000] (BBC catalog # 7030), and as "The Tenth Planet" individual single-tape release in US/Canada [May 2001] (WHV catalog #1529); episodic version, photomontage cover. In all versions, the release of this story was the first three episodes and a full reconstruction of episode 4 by the Doctor Who Restoration Team. In 1992, BBC Video had prepared a release of the story when they believed they had recovered the final missing episode of the story, and had Michael Craze tape a special introduction; this release was canceled, of course, when the recovery turned out to be a hoax.
Audio release
Complete audio soundtrack released on CD as "The Tenth Planet" by the BBC Radio Collection in November 2004, included as part of the "Cybermen Tin" CD set (along with "The Invasion" and the documentary "Origins of the Cybermen"), narrated by Anneke Wills. The score from this story was released in January 2001 by Ocre Records as "Dr. Who: Music From the Tenth Planet". Some selections from this story (music and/or sound effects) have been released on "Doctor Who at the BBC Radiophonic Workshop, Volume One - The Early Years, 1963-1969" (BBC Music WMSF 6023-2).
