Continuity: When Scotty and Cooper leave for London, the airplane taking off has an engine on its tail. The very next shot is of a different airplane that has no engine on its tail.

Continuity: In the scene where the gang is at the Vatican and Jenny tells the guard that Cooper is retarded you see cooper bite into the ice cream cone and it falls apart. However when you see Cooper a few seconds later and the guard talks to him the ice cream cone is back to its original shape.

Continuity: After the graduation, we see Scott writing an e-mail to Meike for the first time in the movie. He writes nearly a line, stops, and the next shot of the computer screen shows that there is about three lines just as he starts typing again.

Continuity: 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.

Continuity: When Mieke and Scott get out of the confessional, Mieke's dress is unzipped. When she walks away in the next shot, it is zipped.

Continuity: At the beginning of the movie, Scott runs over to Fiona and kisses her. She says "Congratulations graduate" and is holding a jacket quite high whilst her arm is bent. In the next shot, her arm is straight and the jacket is down by her waist.

Factual error: Near the beginning of the film there is a map of Europe with the countries coloured in using their respective flags. Great Britain is coloured with the Union Jack (Union Flag) pattern but so is Southern Ireland (Eire). Southern Ireland is not part Great Britain, only the British Isles - they are a separate country and the Union jack is not their country's flag. Only the north or the Irish landmass (Northern Ireland) and Britain should show the Union Jack. If they are using an "old map" it would have to be very old, before the 1920's.

Continuity: When Cooper wears the burning hat, the fire is burning roughly the top third of the hat, yet, in the following shots where he tosses it back and forth with Scott, then throws it in the fireplace, only the tip is burning and everything underneath the small flame is undamaged.

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.

Continuity: When the four friends are walking to the Vatican, they have their backpacks on. In the next shot they reach the Vatican, but their backpacks are missing.

Continuity: In the train station when Jenny meets Cristoph, the trains appear and disappear several times.

Factual error: In the "Berlin intro" with all the German images, a plate can be seen with the text "automatische afsluiting" (automatic closure), which is not German but Dutch.

Continuity: When Cooper is in the hot tub with Candy, there's a blue towel on the chair to left of him. At the very end of the scene, the towel changes to a pinkish striped towel.

Continuity: When Scott tells Cooper he's in love with his pen pal, Scott crosses his arms over his chest. The shot changes and now Scott is leaning forward with his arms resting on the computer desk.

Continuity: 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.

Continuity: The order of the multi colored phallus sex toys on the gasoline-powered machine in Club Vandersexxx changes between shots.

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 Scotty and Cooper first arrive in London, Cooper puts his phone up to his ear twice.

Factual error: When Scotty tries to send Mike an E-mail after she has blocked him, he gets a message saying that he has been blocked. This would not happen as E-mails do not get returned from a blocked address, nor is the sender notified that he/she has been blocked.

Factual error: Absinthe is a very bright pale green, but it does not glow in the dark as seen in the film.
