You've Heard Abrams, Lindelof, and Cuse mention this, and if you didn't immediately know what they were talking about, you are in for a treat. 'The Prisoner' is a limited run British television series from the late sixties produced by Patrick McGoohan. The plot is as follows:
A retired spy awakens in his apartment. Everything is familiar until he walks for the window. Where is the sound of the busy London street he lives on? Why does he feel groggy? He vaguely remembers a man in a top hat, noxious gas, passing out...
He opens the window to find that he is not in his apartment at all, but an exact duplicate situated in an village with a serious lack of architectural identity. He soon learns everyone has a number, his is six, and that everyone in the village is someone who had access to sensitive information back in the word; information that formed the cog-work of governments from all over. Who is in charge? Who is number one? Can he escape before they break him?
