Other mistake: The last shots of Trafalgar square you can see twice a UPS van driving in the background.
Other mistake: On the first day at Stuart's apartment Leopold wears some green 19th century trousers he wasn't wearing during his time travel, and which surely weren't part of Stuart's wardrobe. (00:30:05)
Other mistake: When the guy that is hosting the hair competition is looking up at the old train station display board and going through the names of the salons, The Cut Above is on there, even though they haven't entered the competition at that stage. (00:14:40)
Other mistake: Stifler, Finch, Oz and Jim all have radios. Stifler says during the lesbian scene that they are getting naked. This should have been heard on Jim's radio (he is under the bed), but it is not. We never see Jim turn his radio off as his hands are in shot. (00:43:20)
Suggested correction: It's a bit of a stretch, but maybe Jim had the wherewithal to turn it off (on or offscreen) simply as his radio is most likely to be overheard by the girls themselves, as he Is under their bed (or it malfunctioned somehow, was damaged in the course of all that scrambling about).
Other mistake: During the scene when Nelson takes Sara home after rescuing the puppies, she asks him in for coffee and he doesn't accept. After she tells him she will accept a ride the next morning, he agrees and turns off his car. One of his headlights does not turn off.
Other mistake: After the failed marriage between Jo and Jack, there is a shot of a cliff. Notice that the clouds moving overhead simply disappear into thin air.
Other mistake: During the scene where Thrax is talking to the other germs and viruses in the Zit and is pointing out things on the map of Frank, the word 'collarbone' is spelled wrong ('Collerbone'). (00:52:49)
Other mistake: Amelie only recorded a bit of the Tour de France. When you see it played on the glass man's VCR then there is a bit before she started recording that is being played.
Other mistake: In the beginning of the film when John and Nadia are eating supper together, Nadia gives John a ring and speaks in Russian. The camera is at her back so we can't see her mouth move, but it is definately not Nicole Kidman's voice.
Other mistake: In the courtroom scene near the end of the film, the Apple logo on the laptop is upside down.
Other mistake: At the welcome home party, Peter/Luke is at the piano with the female piano teacher. She is helping him remember how to play a song. Problem is, she is playing the keys right in front of her, and he is playing the keys right in front of him (you can tell by their hand placement and where their eyes are looking), but they are both playing in the same octave. His notes should have sounded at least an octave higher. Furthermore, when he starts playing the jazzy sounding tune, the keys we hear are very low and would have been to the left of the teacher. He would have had to reach across her to reach those keys, but instead he is playing the keys right in front of him.
Other mistake: Victor and Neil leave in the Rally STX van to take the boys to Moose River. Later, when Beth goes into town the license plate number is '566 241' on her Chevy pickup, but when Victor drops Neil and the boys off, we see their Rally STX has the same license plate number '566 241' as well. (00:30:40 - 00:36:40)
Other mistake: After Luis finishes shooting Billy, Bonny goes from being in the first door frame to leaning in the second door frame where Luis just was to being in the middle of the room.
