“Twice Upon a Time” is an episode of the British science fiction television series Doctor Who, written by Steven Moffat, directed by Rachel Talalay, and was broadcast as the thirteenth Christmas special on 25 December 2017 on BBC One. It features the final regular appearance of Peter Capaldi as the Twelfth Doctor, the first official appearance of Jodie Whittaker as the Thirteenth Doctor, and guest-stars David Bradley as the First Doctor, having previously portrayed original First Doctor actor William Hartnell in the 2013 docudrama An Adventure in Space and Time. Pearl Mackie guest stars as the Twelfth Doctor's former companion Bill Potts, while his other companions make guest appearances – Jenna Coleman as Clara Oswald and Matt Lucas as Nardole. This episode is a continuation of events after “The Doctor Falls”, addressing the cliffhanger that it ended on, and takes place during the final story of the First Doctor; footage from the 1966 serial The Tenth Planet, is used in the special. “Twice Upon a Time” is Capaldi's fourth and final Christmas special as the Twelfth Doctor, and the last Doctor Who story to be written and produced by Moffat, who had served as the show's executive producer and chief writer since taking over from Russell T Davies in 2010. After the special's broadcast, Moffat was succeeded as chief executive and showrunner by Chris Chibnall. Since its broadcast, the special has received generally positive reviews from critics.

The episode was written by Steven Moffat and directed by Rachel Talalay, who wrote and directed the two-part finale of the tenth series, “World Enough and Time” / “The Doctor Falls”, respectively. In January 2016, Moffat announced that he would step down as the programme's showrunner after the tenth series, to be replaced by Chris Chibnall beginning with the eleventh series in 2018, but a 2017 Christmas special was not mentioned in the plans at that time. The change in showrunners almost caused the annual episode to be cancelled, as Moffat planned to leave after the tenth series finale and Chibnall did not want to begin his run with a Christmas special. When he learned of Chibnall's plans, Moffat elected to stay long enough to produce one final episode, as he was concerned that the show would lose the coveted 25 December slot in the future if it missed a year. As a result, he had to rewrite his plans for the tenth series finale to allow Capaldi to appear in one more episode. Near the end of the special, the two Doctors part company and return to their respective TARDISes to undergo regeneration. The First Doctor's regeneration is shown, using original footage from “The Tenth Planet”. Although the last episode of the 1966 story is one of the missing episodes of Doctor Who, the regeneration sequence was preserved when it was used in a 1973 edition of the children’s magazine programme Blue Peter. The final scene of “The Doctor Falls” involving David Bradley was filmed as part of the filming of “Twice Upon a Time” in June 2017. Production for “Twice Upon a Time” started on 12 June 2017, and concluded on 10 July 2017. However, the final scene of the episode, in which Whittaker makes her debut as the Doctor, was not filmed until 19 July. The episode had been reportedly titled “The Doctors”, before it was announced at the 2017 San Diego Comic-Con that it would officially be titled “Twice Upon a Time”.
