Continuity mistake: Due to a very poor edit, an extra walking past Number 2 and Number 6 as they talk on the patio disappears in mid-shot.
Revealing mistake: The "metal" door frame in Number 2's office is bubbling and peeling away from the wall.
Revealing mistake: When Nadia and Number 6 are embracing, many of the reverse-angle shots showing them from behind betray the use of a double for Nadia. Nearly every time the camera angle changes, she is noticeably several inches shorter.
Factual error: The truck transporting Number 6 and Nadia drives on the left side of the road. Fine for England, where the scene was shot - but they're supposed to be in Poland, where everyone drives on the right.
Continuity mistake: Nadia's number badge is upside down when she serves Number 6 breakfast. It's turned itself right-side up when she leaves, though.
Continuity mistake: In long shots of the truck transporting Number 6 and Nadia, the crate they're supposed to be hidden in disappears from the truck bed.
Continuity mistake: Nadia and Number 6 go together to the Green Dome (Number 2's residence). While they stand at the entrance, the door knocker changes to one of a completely different design between one shot and the next.
Continuity mistake: Number 2 sits down and places his umbrella beside him with the handle facing out. The camera angle changes, and although he hasn't touched it again, the umbrella handle is now facing inward.
Continuity mistake: When he's playing chess with The General, Number 6's jacket changes between takes. At first it has solid piping on the lapels, then the piping has gaps, then it doesn't again.
Continuity mistake: When Number 6 and Nadia get into the shipping crate, they're both able to stretch out completely for the 12-hour trip. But when the crate is opened, it's suddenly several inches shorter, and 6 has to bend his neck at an uncomfortably sharp angle to fit into it.
Plot hole: When Nadia had been held captive in The Village, how did she get word to her accomplice to be ready at the exact time, in the exact location, and with a packing crate ready, and a whole series of transports arranged? Even if Nadia was in on the ruse of conning Number 6, wouldn't he be suspicious?
A. B. and C. - S1-E3
Visible crew/equipment: When "A" confronts Number 6, as he attempts to leave the party, there is a shot facing Number 6 with a doorman either side of him and if you look in the top right of the screen you can see a boom microphone poke out from behind the door. (00:12:48)
A. B. and C. - S1-E3
Visible crew/equipment: Just before Number 14 talks to Number 6 (in his dream) you can see the shadow of the camera on the piece of equipment she uses to enter his dream as she walks toward it. (00:25:25)
A. B. and C. - S1-E3
Revealing mistake: In the fight at the end of the B scenario, Number 6 has a small problem. His pants split open in the back. Fortunately, they somehow manage to mend themselves again.
A. B. and C. - S1-E3
Continuity mistake: While Number 6 follows Number 14 around the Village, her briefcase keeps switching itself from her right hand to her left between shots, without her having moved it. Later, when she enters the hallway, the case disappears altogether.
A. B. and C. - S1-E3
Continuity mistake: During the dance, the bottle of wine on Number 6's table is sitting on the left side. No one touches it, but when he and B come back to the table, the wine has moved itself to the center.
A. B. and C. - S1-E3
Continuity mistake: Number 14 has to push a button to activate the first tape she puts into the player. She then puts on the 'A' tape and it starts playing by itself, with no button pushed. When she puts in 'B,' though, she has to push the button again.
A. B. and C. - S1-E3
Continuity mistake: When Number 6 kicks out the grill, his socks are blue. In the next shot, though, the socks have turned brown.
A. B. and C. - S1-E3
Continuity mistake: The length of A's cigarette varies considerably between takes. It's short in long shot, then gets suddenly longer in the following close-up.
A. B. and C. - S1-E3
Continuity mistake: Number 6 substitutes clear water for the red-tinted drug in the syringe. But when Number 14 later injects him with the same syringe, the fluid in it has turned red again.
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.
