The Five Doctors - Doctor Who

"The Five Doctors" is a special feature-length episode of the BBC science fiction television series Doctor Who, produced in celebration of the series's 20th anniversary. Written by Terrance Dicks and directed by Peter Moffatt, the episode first aired in the United States on 23 November 1983, the anniversary date, and aired in the United Kingdom two days later. Peter Davison stars alongside returning actors Patrick Troughton and Jon Pertwee. Richard Hurndall portrayed the First Doctor, as William Hartnell, who originated the part, had died in 1975. Tom Baker declined to appear, so his absence was covered with footage from the unfinished serial Shada.
