List of Doctor Who Christmas specials
Doctor Who is a British science fiction television programme produced by the BBC. The show has been a large influence in the media since its inception in 1963. Along with the regular series, special Christmas episodes have also been broadcast since the programme's revival in 2005.
During the first run of the programme (1963 to 1989), while not a Christmas special, one episode aired on Christmas Day: "The Feast of Steven", the seventh episode of the twelve-part serial The Daleks' Master Plan, which aired on 25 December 1965. The episode, currently missing from the BBC archive, was a comic interlude in the style of a pantomime, in the middle of an otherwise epic adventure. In its final scene the Doctor and his companions celebrated Christmas with a toast; the episode ended with the Doctor (William Hartnell) turning to camera (breaking the fourth wall) and saying, "Incidentally, a happy Christmas to all of you at home."
The Doctor learns from the Ood that the Master (John Simm) will be returning soon. A cult of the Master has resurrected him using the ring dropped at the end of "Last of the Time Lords", but Lucy Saxon sabotages the process, causing the Master to experience intense hunger and energy expenditure, which also gives him powers beyond those of other Time Lords. In his investigations, the Doctor meets up with Wilfred Mott and they both travel to the Naismith Institute where they have enlisted to repair an alien "Immortality Gate". However, the Master uses the gate to re-write the DNA of all humans on the planet with his own, creating a planet of Masters. Donna Noble (Catherine Tate) and Wilf (Bernard Cribbins) are shielded from this. Far across the universe, Rassilon (Timothy Dalton) heralds the return of Gallifrey and the end of time itself.
