Continuity mistake: A man attacks the judge by running out of the shower. When he runs through the shower, a shower curtain is draped over him. For most of the scene it is over his head, but when he is dragging the judge into the shower, the curtain has moved off of his head and is even gone completely in one shot, perhaps to make the actor more visible.Movieman123
Continuity mistake: When they are talking to the two kids outside of the school for the first time, one of the kids has a juice box. Shawn starts talking and it shows from behind the one kid with the juice box and he is about to take a sip, then the shot changes and the juice box is by his side.Movieman123
Continuity mistake: When Shawn calls the first student up to the board to write a number, firstly the written number is 6.00214, which is an incorrect Avagadro's number, but it is not always this incorrect number. At some point during filming somebody changed it to the correct number: 6.02214, and you can see the number actually changing back and forth between the two numerous times during this scene.
Continuity mistake: In the restaurant, Byrd slamms Tancana's face into a burger and mustard/ketchup smears across the left side of his face and nose. In the echo, the condiments are on the opposite side of his face. After Tancan drops down behind the seat and then reappears, most of the condiments have been removed, but the glob on the left side of his nose is lower and more on the top of his nose than it had been before. (Not a change that would have happened from him rubbing it off and missing some.) The blob continues to migrate throughout the rest of the time they are in the car.
