The Prisoner

According to script editor and co-creator George Markstein, Number Six resigned from his position after discovering files indicating the existence of the Village. The Village was an idea Number Six had submitted to his superiors many years before but had since decided was monstrously inhuman.

The building in Portmeirion shown as Number Six's house in the series became a gift shop selling Prisoner-related merchandise.

The Butler (played by Maltese actor Angelo Muscat) never speaks, and appears in more episodes than anyone else other than Patrick McGoohan.
