Doctor Who: The Mind Robber
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 TARDIS jumps right out of space and time and into the Land of Fiction, a white limbo where imagination can turn into a deadly reality. Can the Doctor (Patrick Troughton) and his young friends defeat the land's master and get back to their own universe?
