Continuity mistake: When Austin is about to be sent back in time in the Bug, he reverses into some shelves with computers on them, knocking them over. He then pulls forwards. When he reverses again, the computers are back up, and he hits some barrels. When he pulls forwards again, the barrels are back up, but the computers have now disappeared again.
Continuity mistake: During the scene in which Mini Me draws the "goodbye card" to Scott, (which, as explained already on the list was drawn ahead of time), there seems to be a red spot under Scott's body on the paper, no doubt signifying blood. But where did he get the red marker to draw it?
Continuity mistake: When Austin and Felicity are having a fun time in London, they stop and sit down at a table. Shortly after they sit down there is a lady behind Felicity in yellow and orange. Then it cuts to Austin, and she's behind him as well! There is no way someone could move that fast. Originally I thought that was the waitress outfit, so there could be more than one, but it's definitely the same woman both times, and on wider shots we only ever see one woman.
Continuity mistake: After the assassin throws the knife into Robin Swallows' back, the shot cuts to the assassin. But when it cuts back, Austin is looking quizzically at her back, and we see why. The knife has disappeared! But in all subsequent shots (except when she falls and hits the ground) it is there.
Continuity mistake: When Fat Bastard explodes through Austin Powers' bedroom door, you can see where his right arm was meant to break through, but didn't. The piece of the door is shown still intact for a moment or two, but with the outline of his arm surrounding it. It disappears in the very next shot of the door only a second later.

Continuity mistake: In the scene where Austin and Felicity are downtown on the sidewalk, they alternate long and closeup camera shots from the same angle. There is a crowd of people standing around watching them in the background on the long shots, but only individuals walking past, ignoring them, in the closeup shots.
