Doctor Who: Meglos

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.

It's a prickly situation (sorry!) when a cactus-like chameleon creature called Meglos impersonates the Doctor (Tom Baker) in order to steal the planet Tigella's power source, the Dodecahedron. 86 min. Standard; Soundtrack: English Dolby Digital mono; Subtitles: English (SDH).
