Season 21 (Doctor Who 1963)

Season 21 of Doctor Who ran between 5 January 1984 and 30 March 1984. It starred Peter Davison as the Fifth Doctor. The last story, The Twin Dilemma introduced Colin Baker as the Sixth Doctor.

Overview

The season consisted of seven serials and twenty-four episodes. The Twin Dilemma, the first story with Colin Baker as the Sixth Doctor aired last in the season. This season saw the departure of companions Tegan, Turlough and Kamelion and introduced Peri. Most episodes were the traditional twenty-five minute length. However, due to coverage of the 1984 Winter Olympics, Resurrection of the Daleks was re-edited before airing and shown as two forty-five minute episodes.

Colin Baker's first story, The Twin Dilemma, introduced a modified version of the opening credits including a slight modification to the series logo (although the theme arrangement was not changed). This was the first time since Season 4 that such a change occurred during a season.

Along with Season 4, it was one of only two seasons of the classic series to have a completely different cast in the final story of the season than in the first story.
