Other: When Scott is writing Mieke back for the first time, we see him typing on the keyboard, but no letters appear on the screen.

Continuity: When the group is at the dinner table in Paris, Jenny says "We can go to Denmark," and Cooper has his wine glass in his hand. In the next shot we see Cooper, and his arm is down with no wine glass. In the next shot, the glass is back in his hand again.

Continuity: 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.

Factual error: Near the end of the movie, when Mieka is shown in the Vatican, she is wearing a dress without any sleeves that does not cover all of her legs. This would never be allowed in the Vatican because of the dress code, which is long pants and long sleeves, and the same holds true for men's attire, such as shorts.

Continuity: In the scene where Cooper visits the Amsterdam pleasure house, he is given a safe word. When he is given this word, the woman directly on his left, the one in the pink sparkle shirt, you can see her breasts and not under her shirt. When she goes to strap his ankle to the metal structure in the next shot, her breasts are under her shirt. When she straps his wrist to the same structure two seconds later, her breasts are back out again.

Continuity: At the end of the movie while Cooper is hugging Jamie at the airport, Jamie switches the bag he is holding from his right hand to his left hand. When the shot changes, the bag is back in his right hand.

Continuity: When Fiona hands Scott the Letter Jacket, the shot cuts to a tighter view, and the people behind Scott change from one shot to the next.

Factual error: Amsterdam doesn't resemble the "real" Amsterdam at all, including the infamous Red Light District. When walking alongside the highway, it's clear that it's not a Dutch highway. The supposedly Dutch characters speak with an Eastern European accent, because the "Dutch" scenes were shot in Prague, the Czech Republic.

Continuity: After Jaime introduces his Leica M7, he switches from swatting Scotty with his left hand to his right hand and back.

Audio problem: When the four friends are in a French restaurant and Scotty, Cooper, and Jenny are trying to persuade Jamie to join them on their quest to Germany, Scotty's line is heard as "I Love Denmark," but his mouth forms the words "I Love Amster," as if he was in the process of saying Amsterdam before the shot changed.

Deliberate "mistake": When Madame Vandersexxx writes the safe word onto the piece of paper, she writes it way too fast and scribbly for it to be perfectly written as shown when there is a close up of it when Cooper is reading it.

Factual error: When Scott and Cooper throw the burning hat in the fireplace, the smoke is seen coming out of the chimney in the Sistine chapel. Though this adds a bit of hilarity, the chimney is only able to be used when constructed in preparation for the Conclave of all conclaves, the election of the new pope.

Continuity: 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: In the scene where the gang first meet with the weird Italian guy in the train and he puts his hand on Jamie's leg, look at Jenny. She is sitting right next to Scotty but when Cooper and Jamie run to the opposite side of the coupe she is sitting about a metre away from Scotty.

Factual error: When Scotty and Cooper are walking into the airport to get courier jobs to go to Europe, a European road sign can be seen behind them. It is blue with a red X on it.

Continuity: When Scott and Cooper meet up with Jamie and Jenny in Paris, at the end of their conversation Jamie says "Let's go to the Louvre." When he says this his book is down by his side. In the next shot he has the book open in front of him. The shot changes again, and again the book is down by his side.

Continuity: 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.

Continuity: When Scott is doing his robot act on Cooper, he gets really close to Cooper's face. In the next shot he is at a further distance away.

Continuity: Madame Vandersexxx writes the safe word starting in the middle of the slip of paper, but when Cooper looks at it later, it starts on the left side of the paper.

Other: When Scotty and his friends sit in the train driving from Crans Sur Mer to Amsterdam, Scotty reads his e-mails from Mieke again. However, most of the e-mails make no sense or are not written as if from one pen pal to another (e.g. in one e-mail, a 'Sandra' is asked how her job is going).
