Continuity mistake: In the graduation party scene, when the band starts singing "Scotty Doesn't Know": Just as the main chorus kicks in, Kristin Kreuk starts dancing on stage. The film cuts from a close up to a wide shot of the stage and Kristin is waving her red jacket around and throws it in the crowd. The shot then goes to close up and mysteriously the jacket is back on her again. It's short and you can only see parts of her shoulders, but they are red. (00:09:10)
Continuity mistake: When Jenny, Jamie, Cooper, and Scott are walking down the Amsterdam highway, they switch places from shot to shot. First shot we see is of their feet and you can see Jenny is on the left hand side in front, and Jamie is on the right hand side in back. The shot cuts and now Jamie is in front, left hand side, and Jenny is on the right hand side in front. When the shot changes again they switch shots. (00:55:15)
Continuity mistake: When Cooper is at the sex club and the dominatrix Madame Vandersexxx hands him the paper with the safe word on it, he takes it and goes to put it in his shirt pocket. The scene cuts and he is holding it in front of him again, then in a few seconds puts it in his shirt pocket. (00:50:30)
Continuity mistake: The order of the multi colored phallus sex toys on the gasoline-powered machine in Club Vandersexxx changes between shots.
Continuity mistake: In the Vatican confessional, a woman comes to confess and sees Mieke's behind through the window. The camera angles from the inside and outside don't match up to make this possible. (01:20:15)
Continuity mistake: When the gang first arrives at the Vatican (as soon as the "map" shows them travel across the table to Italy), there is a very quick shot of them walking down an alley. Scotty says "there it is" and they walk toward a door with a sign above it (in English, for some reason) that says "Summer at Sea". The shot then changes and they are walking up to the Vatican guards. I guess there was supposed to be a scene where they went to the Summer at Sea office to find "Mike" but it was deleted. It wouldn't make sense, since they knew she was going to the Vatican anyway.
Continuity mistake: When Scott asks the soccer hooligan where they are going (when they're on the bus), you can see that right at this moment the bus is about to pass underneath a bridge. The shot changes, but there isn't any visible indication that they passed underneath the bridge. (00:26:05)
