Back in the sixties, one of my favorite shows was The Prisoner, a really smart series starring Patrick McGoohan as a retired British spy who knew too much. When he tried to retire, he found himself in the Village, attempting to escape every week. Very smart and influential series. More from Wikipedia:
The Prisoner is an allegorical British 1960s science fiction television series starring and co-created by Patrick McGoohan. It follows a former British secret agent who, after abruptly resigning from his position, is held captive in a small village by the sea by an unidentified power that wishes to establish the reason for his resignation. Episodes typically feature the unnamed prisoner, labelled "Number Six" by his captors, unsuccessfully attempting to escape from "the Village", but successfully resisting interrogation and attempts of brainwashing.
Turns out, the folks at AMC who brought us the great show "Mad Men" are reinventing the show, and so far, it looks like they're doing so with integrity.
