One of the most popular shows in British TV history, this long-running, shoestring-budgeted sci-fi saga followed the exploits of "the Doctor," a maverick scientist and adventurer who traversed space and time in the TARDIS, a high-tech craft disguised (well, stuck, actually) as a London police box. William Hartnell, Patrick Troughton, Jon Pertwee, Tom Baker, Peter Davison, Colin Baker, and Sylvester McCoy starred as the various eccentric incarnations of the Doctor during the series's initial 1963-1989 run.

The Doctor (Jon Pertwee) must save the members of a global-peace conference from becoming the latest victims of the Master, whose weapons are a stolen nerve gas missile and a parasitic alien that feeds on evil thoughts. With Nicholas Courtney, Katy Manning. 146 min. Standard; Soundtrack: English Dolby Digital mono. Two-disc set.
