Season 4

Season 4 of Doctor Who ran from 10 September 1966 to 1 July 1967. It starred William Hartnell as the First Doctor in the first two stories and then Patrick Troughton as the Second Doctor and Michael Craze as Ben Jackson, Anneke Wills as Polly Wright and Frazer Hines as Jamie McCrimmon. The season opened with The Smugglers and concluded with The Evil of the Daleks.

Overview
The season consisted of nine serials comprised of forty-three episodes. This season was a season of major changes for Doctor Who, including some that have influenced the series and franchise ever since.

Most notably, season 4 saw William Hartnell's First Doctor hand the baton to Patrick Troughton's Second Doctor in the very first regeneration. When Hartnell announced his plans to leave the series, the show's writers came up with the idea of having the Doctor change his appearance and personality. In 1966, while it was not uncommon for actors to change in ongoing TV and film roles, this was possibly the first time a change in appearance was written into the very nature of the character.

The renewal (a process which would not be referred to as regeneration until some years later) occurred in The Tenth Planet, the second story of the season, which carried double significance in that it also introduced the Cybermen, a recurring menace that would quickly establish itself in a strong second-place position behind the Daleks in the Doctor Who rogues gallery. As for the Daleks, an era ended with the series finale, The Evil of the Daleks, which at the time was expected to be the final Dalek story ever. Ultimately, a Dalek later made a cameo in 1969's The War Games and the Daleks returned full-time to Doctor Who in 1972's Day of the Daleks.

The season introduced companion Jamie McCrimmon, one of the longest-serving and most popular TV companions. The season also introduced Victoria Waterfield - originally and briefly with Denise Buckley cast in the role during production, before this was changed to Deborah Watling.

The Highlanders, broadcast this season, marked the end of the writers including occasional "historical serials" which featured no fantastic elements other than the TARDIS and the crew themselves. The next pure historical story would not appear until Black Orchid in 1982.

For most of the season, the opening sequence, theme arrangement, and logo of the Hartnell era was retained. Beginning with The Macra Terror, however, a new opening sequence was introduced, and along with it a new series logo and a modified arrangement of the theme music (introducing the "electronic spangles" sound and the tape echo effect that would both be retained through to 1980). Most significantly, this new opening established the tradition of showing the current Doctor's face which persisted for the rest of the programme's original run.

Season 4 consisted of forty-three episodes which made up nine serials, the majority of which are considered lost; this season has the distinction of being the only Doctor Who season for which not a single story survives in complete form (although audio recordings exist for all the episodes which has allowed cassette and CD reconstructions of the stories to be commercially released. Episode 4 of The Tenth Planet, The Power of the Daleks, The Moonbase, The Macra Terror, The Faceless Ones and The Evil of the Daleks received animated reconstructions. The opening sequence of 2017 story, Twice Upon a Time, recreated parts of Tenth Planet that were lost).

It was during season 4 of Doctor Who that its long-standing rival, Star Trek, first aired on American television.

Along with season 21, 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.

DVD & Blu-ray releases
Five serials of season 4 that were released individually on DVD have had their missing episodes reconstructed through animation; The Tenth Planet, The Power of the Daleks, The Moonbase, The Macra Terror and The Faceless Ones, from 2013 to 2020. The Underwater Menace episode 3 was previously released on the Lost in Time box set prior to the recovery of episode 2. Both episodes were later released on DVD in 2015 with telesnap reconstructions of episodes 1 and 4, after plans for animated reconstructions of the missing episodes fell through.

The Power of the Daleks was the first wholly missing serial to be completely reconstructed using animation. It was also the first to have its missing episodes animated in colour, and the first Patrick Troughton serial to be released on Blu-ray. Subsequent releases of animated missing serials have been released on Blu-ray, DVD and digital streaming with colour and black & white animation.
