Season 20 of Doctor Who ran from 3 January 1983 to 16 March 1983. It starred Peter Davison as the Fifth Doctor, Sarah Sutton as Nyssa, Janet Fielding as Tegan Jovanka and Mark Strickson as Turlough. The season opened with Arc of Infinity and concluded with The King's Demons.

Overview

It consisted of six serials comprised of twenty-two episodes. This was notable for the degree to which it varied from its original plans. It had been commissioned as a 28-part series, and the intent was that it would have actually been broadcast towards the end of 1982. Producer John Nathan-Turner had hoped to use season 20 as a way to reverse the January-March broadcast of season 19. Thus, he had initially obtained permission to record and broadcast season 20 in 1982, thus making season 21 broadcast over the milestone 23 November 1983. Had JN-T got his way, the twentieth anniversary special would have in fact been a part of the regular twenty-first season.

Although this idea was in fact greenlit, permission had to be rescinded when it was discovered that Davison's second job — the then-popular BBC One comedy, Sink or Swim — wouldn't allow for this more aggressive Doctor Who production schedule. BBC One controller, Alan Hart, had to personally step in to settle the dispute between the two production teams, and he "awarded" Davison to Sink or Swim. This meant that season 20 would, like its predecessor, be broadcast in the first quarter of 1983.

Hart, however, did want some sort of anniversary special in November, so he suggested that JN-T put the money for two of the 28 episodes aside to allow for the special. This, of course, meant that there would now be 26 episodes in season 20. In the end, however, the final four episodes — meant to go towards a Dalek adventure that eventually became season 21's Resurrection of the Daleks — were left on the table because of a union dispute. Thus, as transmitted, season 20 consisted of just 22 episodes.

Meanwhile, the anniversary special, which was originally envisaged as a part of season 21, was something quite separate from any season. Although it used a portion of the original money involved in the season 20 commission, it received a separate commission from Head of Series David Reid on 15 July 1982. Indeed, it only received this commission because JN-T had been able to secure co-production money from the main Australian network. Moreover, The Five Doctors, as the production was eventually called, didn't begin principal photography until early March 1983 — just when season 20 was wrapping transmission on television.

The Five Doctors, though often said to be a part of season 20, was therefore not a part of season 20 in any production or broadcast sense. Indeed, it's doubtful that any contemporary viewer thought of it as a part of the season, since it came almost eight months after the closing scene of The King's Demons. Instead, it had much greater production and broadcast proximity to season 21, and is often considered a standalone special. The episode was also considerably longer than typical episodes of the time, and was introduced during the Children in Need telethon by the host, Terry Wogan.

Structurally, the season retread season 18's formula of including a trilogy of stories bound together by an overarching theme. In this instance, the tripartite tale involved Turlough's attempts to kill the Doctor at the behest of the Black Guardian.
