Revealing mistake: In the first 15 minutes of the movie, when Megan is in school and about to open her locker, she turns the lock even though you can see that the locker was already open.
Revealing mistake: In the beginning of the movie, when Jakob is chasing the newspaper, there are several times you can see the string they use to drag it.
Revealing mistake: Garriss compliments Marie on her new hair dye, but she is obviously wearing a blonde wig. (01:20:30)
Revealing mistake: When Lucille sees her children through the prison window the bars must have been copied in later. In slow motion you see that they are transparent. (01:20:50)
Revealing mistake: When Imhotep transports Evie, Beni and himself back to Hamunaptra, Evie hears the plane and looks up. Before she states "O'Connell," you can see the letters and numbers on the side of the plane are backwards, like a mirror image - it says "B5538" backwards, which resembles "BE228" (no mirror). (01:32:15)
Revealing mistake: In the game where Moxon has the 40-yard Scramble (against the Broncos) Tweeder seems to teleport around the field. He starts out on the far side (waving his hands), then has a block on the far side (as witnessed by the close yard marker), the scene cuts and he's on the near side of the field blocking (Moxon runs behind him), then he's on the far side (as Moxon gets up from diving Tweeder is behind him). Some fancy editing going on there.
Revealing mistake: When the cheese sandwich in the toaster catches fire, it engulfs the cookies. When the camera is tightened in on the boxes of cookies, you can see a petrol line running down the cookies.
Revealing mistake: When Sheila asks if Terrance and Phillip have any last words, Phillip says, "Last words, how's about get me the f**k out of this chair!" When he does, his arm leaves the arm of the chair and goes through the restraint, which reappears instantly after. (01:03:00)
Revealing mistake: During the opening sequence, when the fish and game officer is just about to be attacked while looking inside the nest, there's a clear reflection of his lower body as the camera moves closer from behind him. This reveals the diver is in some type of tank, otherwise, this could be a piece of equipment, like Plexiglas (or similar,) put in place within a real body of water for filming purposes.
Revealing mistake: In almost every scene that the crab is in, just watch the space above it and you can see strings moving it.
Revealing mistake: Pnub's (Elden Henson) head in the scene where Anton kills the two cops is obviously animatronic, it's eyes are clear blue and Pnub's eyes are brown.
Revealing mistake: When the guys go to see Tom at the BBQ, he has his head in a support cage. Every time he moves, and particularly when he laughs, this cage moves around and wobbles. The point of these cages is to keep the head still and in line with the spine, and are bolted into the bone itself. Therefore, not only should it be impossible for it to be moving, it would seriously hurt if it was.
Revealing mistake: At the end when it shows Dooley and Jerry-Lee filming the exercise video, Dooley has a plaster on his head in the exact place he had one when it showed Dooley trying to get Jerry-Lee to jump off the roof.
Revealing mistake: As the Spleen and Invisible Boy stand silhouetted in front of the moon, their motions are easy to tell as the film being run forward and backwards.
Revealing mistake: When the toys are watching Woody being stolen the games machine on top of the TV doesn't have its controllers plugged in, but Rex was playing earlier with a wire coming out of his controller, which clearly wasn't actually connected to anything.
