Continuity mistake: Between the time the coded note is tied to the pigeon and the time it is intercepted and handed to Number 2, the handwriting on it changes completely.
Continuity mistake: When he's standing against the wall of the kosho chamber, Number 6 is holding onto the rail, but when the camera reverses angles, he isn't. This goes back and forth several times.
Continuity mistake: During Number 6's visit to the Village Shop, the blue and yellow signs in the window switch places between takes, then return to their original positions.
Continuity mistake: Number 6 recites a classified ad in Spanish to the young woman at the newstand. His phrase contains eight words, but when she reads them back, there are nine.

Continuity mistake: The cape Monique is wearing disappears when she's in the watch shop, then reappears a few shots later.
Continuity mistake: A sleeping Number 6 is being observed by the Village girl. While she watches him, his bed clothes mysteriously rearrange themselves. First they're disarrayed, then they're neatly tucked over him and his robe has moved to a different place on the bed. A few shots later, when he wakes up, his pillow disappears.
Continuity mistake: When Number 6 buys soap and candy from one of the Village vendors, he removes his payment card from his pocket three different times without ever having put it back.
Continuity mistake: During the scene in the bell tower, watch the beach in the background. In one take, the tide is in. In the next, it is suddenly at low tide, with much more of the beach exposed.

Continuity mistake: There are many shots of The Colonel (whose mind has been switched with Number 6's mind) driving KAR 120C all around London. The footage is stock, shown in other episodes, and features either Number 6 or his stand in, but definitely not the Colonel.
Continuity mistake: Number 6 is sitting in jail rolling a cigarette. In the long shot, you can see that he's just exhaled a cloud of cigarette smoke. But, in the next shot, he has just finished rolling the cigarette and has yet to light it. (00:11:10)
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.
