Take The Prisoner, which appeared in Britain in 1966-67, and on PBS in the mid-1970s.
The mysterious Number Two, who is in charge of the Village, wants "information." Number Six wants to escape, or, failing that, to find out who his keepers are. But plots soon moved beyond the "Why did you resign?" maguffin to explore questions of conformity and individuality.

McGoohan starred in many other movies during the 1970s and 1980s. He is perhaps most famous for playing King Edward in Braveheart (1995), and eliciting homophobic audience cheers by pushing his gay son's lover out a window. Not that I believe McGoohan, who died in 2009, actually condoned throwing gay people out of windows.
