Doctor Who season 4

This article is about the 1966–67 season. For the 2008 series, see Doctor Who series 4.

The fourth season of the British science fiction television series Doctor Who began on 10 September 1966 with the First Doctor (William Hartnell) story The Smugglers and, after a change of lead actor (Patrick Troughton) part-way through the series, ended on 1 July 1967 with The Evil of the Daleks. For the first time, the entire main cast changed over the course of a single season (the only other occasions this has happened are during Season 18 and Season 21).

Serials

Season 4 was produced by Innes Lloyd. Gerry Davis served as Script Editor, apart from the final four episodes of The Evil of the Daleks. Peter Bryant joined as associate producer for The Faceless Ones, and replaced Gerry Davis as script editor for the last four episodes of the season.

The Smugglers was the final serial to be produced during the third production block, but was held over to the start of Season 4.^[1]

The Tenth Planet introduced the Cybermen and the concept of Regeneration, which wouldn't be named so until Planet of the Spiders in 1974.

The Power of the Daleks was the first Dalek story to use the traditional ...of the Daleks title form. Of the nine subsequent Dalek serials, only Death to the Daleks from Season 11 was not named in this way. The naming convention for Dalek stories was first used in the revived series with "Evolution of the Daleks" in Series 3.

None of the nine serials from Season 4 are complete in the BBC archive, with four (The Smugglers, The Power of the Daleks, The Highlanders and The Macra Terror) each having all of their episodes missing; of the total of 43 episodes between "Episode 1" of The Smugglers and "Episode 7" of The Evil of the Daleks, only 10 are currently in the BBC archive. The most complete serial of the season, The Tenth Planet, is missing only its last episode; this serial, as well as The Power of the Daleks, The Underwater Menace, The Moonbase, The Macra Terror, The Faceless Ones and The Evil of the Daleks have had their missing elements recreated with animated episodes using the original soundtrack. The fully animated serials are presented in both colour and black and white formats, while The Tenth Planet and The Moonbase animations are presented exclusively in black and white.
