The End of Time

"The End of Time" is a two-part story of the British science fiction television series Doctor Who, originally broadcast in the United Kingdom on BBC One on 25 December 2009 (Part 1) and 1 January 2010 (Part 2). It is the fifth Doctor Who Christmas special and the last entry in a series of specials aired from 2008 to 2010. It marks the final regular appearance of David Tennant as the Tenth Doctor and introduces Matt Smith as the Eleventh Doctor. At the time, it was the last Doctor Who story written and produced by Russell T Davies, who shepherded the series' return to British television in 2005 and served as the series's executive producer and chief writer. He returned to that role in 2022 in time for the 60th anniversary specials. Davies was succeeded as executive producer and showrunner by Steven Moffat. Bernard Cribbins, who appeared in the story "Voyage of the Damned" and throughout Series 4 as Wilfred Mott, grandfather of Donna Noble, acts as the companion to the Doctor in this two-part story. The special also features the return of many other actors to the show, including Catherine Tate, John Simm, Jacqueline King, Alexandra Moen, Billie Piper, Camille Coduri, Freema Agyeman, Noel Clarke, John Barrowman, Elisabeth Sladen, Tommy Knight, Jessica Hynes and Russell Tovey. The story features the Tenth Doctor (Tennant), who has been running from a prophecy of his impending demise, as he is drawn into a scheme by his old nemesis, the Master (Simm). The Master brings the human race under his control as part of an elaborate plan to restore the world of his and the Doctor's own people, the Time Lords, from their demise in the Time War referred to in the series. The Doctor is able to avert this, but incurs fatal injuries. In the episode's conclusion, as has happened before, the Doctor regenerates and becomes a new man with a new personality and physical traits, setting up the show's following series with Matt Smith as the Eleventh Doctor and Steven Moffat as executive producer.
