Deliberate mistake: The credits list "Number 86" as played by John Maxim. But no such character appears in the episode. Apparently, 86 was left on the cutting room floor, but the titles weren't altered accordingly.
The Prisoner (1967)
1 deliberate mistake - chronological order
Starring: Patrick McGoohan, Angelo Muscat, Peter Swanwick
Continuity mistake: Number 6 chooses a rather thin tree to cut down and fashion into his canoe. Somehow, when he's finished hewing out the wood to form the boat, it's considerably wider than the tree he started with.
Number 6: Unlike me, many of you have accepted the situation of your imprisonment, and will die here like rotten cabbages.
Trivia: This episode was not shown in the initial U.S. airing of "The Prisoner" on CBS. There was speculation that its pacifist, anti-violence moral might have been construed as a Vietnam War protest, but the network's reason for censoring the episode has never been disclosed.
Question: What exactly was Rover? Was it some sort of automated robot?
Chosen answer: We're led to believe Rover is some kind of robot in the series. According to books on the show, Patrick McGoohan was looking for an unusual guardian for the Village, looked up at the sky, and saw a weather balloon, which was what Rover was.
