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

Patrick McGoohan was so averse to on-screen romance that in the scenes in 'Chimes of Big Ben' when he has his arm around Nadia and is stroking her hair, it is actually McGoohan's own daughter in a wig.
