Continuity mistake: When Passepartout and Fogg arrive at The Royal Academy of Science explaining about breaking the speed barrier, Lord Kelvin asks where his authorization is and mocks Fogg while laughing and lowering his right arm. When it cuts, his arm is back up to his stomach. (00:13:00)
Other mistake: In the end when everyone is on the Kippie Kann show, they show the clip of Lulu and Joyce at the restaurant. It shows Lulu saying, "I'd say it's nice to see you, but then I'd be lying." In the restaurant scene, Lulu never says that.
Continuity mistake: When Derek arrives at the house party he gets a blue drink off a tray, yet when he manages to get away from the jocks its disappeared.
Plot hole: When Dan is chasing after Carter to catch him and Alex together at the restaurant, there's very little chance he could have had any idea where Carter was going. He couldn't have told the cab driver to "follow that taxi" because in the time between Carter getting in a cab and Dan getting in a cab about 5 taxis drive past, so how he happens to end up at the same place is a miracle.
Revealing mistake: At the beginning of the movie a hamburger is thrown in hopes that a dog will "fetch" it. When the dog does not do so the hamburger is retrieved twice, in perfect shape, to be thrown two more times. On each throw its various parts would have landed individually all over the place and not been throwable again.
Continuity mistake: When Jack and Miles pull up to the house to retrieve the wallet, one of the drapes is pulled back in the front window. When Miles walks up to the house, both drapes are drawn over the window.
Continuity mistake: In the scene where Alfie sees Julie in the cafe with Adam, he walks out to his scooter. They show him put on his scarf. Then for a second, it disappears, then reappears.
Revealing mistake: During the wedding scene, while the narrator is talking, you can see the string that will pull the left table apart. As said in the commentary, the filmmakers weren't going for the idea of people pulling the tables apart, but rather some other force parting them. (01:27:40)
Factual error: At the beginning of the episode where the school gets a news broadcast, Mary Ferry says that the first broadcast will be the following Monday. Later in the show, however, she is talking to Addie at school and says that the first broadcast is the next day. If that was true, it would be Sunday, and they would not be in school, and they never changed the date of the broadcast.
Continuity mistake: As the girls run from the killer, the one girl is shirtless as she starts to run, holding her shirt in front of herself to cover her chest. The camera changes to a rear view and now she is running with the shirt in her hand swinging wildly. The camera changes again and suddenly she is running and putting her shirt on, already pulled over her head, a major change from the last shot. Finally, the camera angle changes again and she has her shirt on completely. All of her shirt/hand positions change instantly between shots.
Continuity mistake: In Desmond's car, Roy puts on his left sock first, then crosses his right foot over his lap. The shot switches behind him and he is putting his left knee up into the frame. The angle changes again and he puts the sock on his crossed right foot. (00:34:15)
Continuity mistake: When Ben Stiller picks up the Vapoorise to throw it in the bin, he picks it up with his right hand, but he throws it with his left.
Factual error: The stadium in the opening scene was not around in 1995. The first game played in that stadium was 2001.
Continuity mistake: During the basketball match, when the big guy is making a lot of noise, guards come up to him from the front and behind to take him out of the arena. The guy at the back puts his right arm over the big guy to his chest, but in the front view, that guard doesn't have his arm across his front anymore. (00:03:15)
Revealing mistake: When Gene's bodyguard (the one with the moustache) shoots Slasher and Duke, just before Slasher is shot the bullet hole effect is visible on her forehead (sightly concealed by make-up) just before the actual 'shot'.
Other mistake: When James Gandolfini hits Ben Affleck over the head with the shovel for burning something in his front yard, he falls, but his head never hits the ground. You can actually see Ben Affleck holding his head up a few inches off the ground. An impossible feat for someone who is supposed to be unconscious.
