Season 21

Season 21 of Doctor Who ran from 5 January 1984 to 30 March 1984. It starred Peter Davison as the Fifth Doctor, Janet Fielding as Tegan Jovanka and Mark Strickson as Turlough for the majority, whilst the final serial featured Colin Baker as the Sixth Doctor and Nicola Bryant as Peri Brown. The season opened with Warriors of the Deep and concluded with The Twin Dilemma.
== Overview ==
The season consisted of seven serials comprised of 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. In this case, Janet Fielding, Mark Strickson and Peter Davison, respectively, departed their roles in three consecutive serials.

Target Books was originally unable to come to an agreement that would have allowed Resurrection of the Daleks to be adapted as a novel. However, Eric Saward eventually novelised the story in collaboration with BBC Books in 2019, 35 years after the story first premiered on television.
