The 118th episode of Doctor Who airs on the BBC. This is part four of the story now collectively known as The Gunfighters. This is the final episode of the original series with an episode title independent of the story’s overall umbrella title; all future episodes will simply be “part one,” “part two,” etc. of their respective stories.
This timeline entry leads to an entry covering this entire Doctor Who serial; there are plans to write new episodic entries in the future. You can support this effort!

With the series’ two most recent producers reporting that actor William Hartnell has become nearly impossible to work with, the first steps are taken to regenerate Doctor Who by hiring a new actor to play the part: Patrick Troughton. In closed-door meetings at the BBC, producer Innes Lloyd and BBC Head of Drama Sydney Newman (who also happens to be Doctor Who’s creator) offer Hartnell the chance to leave, and – having already taken the liberty of contacting him to gauge his interest in the part – contract actor Patrick Troughton to replace Hartnell as the Doctor. Hartnell, suffering from arteriosclerosis, accepts the escape hatch and agrees to leave the series. Lloyd and Newman begin brainstorming ideas to explain the radical change in the Doctor’s look, agreeing that the time has finally come to firmly establish that the Doctor is not human at all. Lloyd envisions a tough “pirate captain” persona for the new Doctor, a notion ultimately rejected by Newman, who instead proposes that the character be played as a “cosmic hobo,” an idea which Troughton likes much better. None of this activity is revealed to the press or the public for some time.
The feature film 
The BBC informs the press that major changes are afoot for the popular science fiction series Doctor Who – namely, that the last remaining original cast member, William Hartnell, will be leaving the show, and that producers are already searching for a new actor to take on the role (though, in reality, they have already hired Hartnell’s replacement and are scrambling to reformat the series to allow for the unprecedented swap of its main star). When contacted by British newspapers for a reaction, Hartnell confirms the news.
