Continuity: 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.

Continuity: After Nadia and Number 6 are placed into the packing crate, there's a shipping label on the front. In the next shot, it's vanished. Later, it reappears, but is now on the crate's side.

Other: When No.8 has been caught by "Rover" in the sea, she is pulled back unconscious to land by one large Rover and 2 smaller Rovers (one on each arm). Her legs are seen to kick (swimming style) to help them move.

Continuity: 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.

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.

Revealing: The "metal" door frame in Number 2's office is bubbling and peeling away from the wall.

Continuity: 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: 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.

Revealing: 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.

Continuity: 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: 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: 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: 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.
