Continuity mistake: After Shane Wolfe and Mrs. Plummer retrieve GHOST and then see the children, as Principle Fletcher jumps on Mr. Chun, you can see all of the police officers reach for their guns and Shane bend slightly to seem like he is reaching for something. As the shot changes to behind Shane and the police officers, Shane is holding the gun that Mr. Chun had and the officers to his left are reaching for their guns, but the officers to his right still have their hands up. When the shot changes to show their faces, Shane is standing there empty handed and all of the officers now have their guns in their hands.
Continuity mistake: When Vin Diesel does the panda dance to get to the safe, all the stuff comes down, including pins and gates. In the next shot, you see all the gates and pins going back up, except for one. When the camera changes angle, the pin is up, even though there isn't such a big time difference to have the pin go up, and the viewer not to see.
Continuity mistake: Near the end of the movie when Captain Fawcett is pointing the gun at Wolfe and Mrs. Plummer, the safe's door springs back to knock him out. At the moment the safe's door seems to be about 80 degrees open, yet when Shane opens the safe for himself, it appears to be about 30 degrees open.
Continuity mistake: The wrestling coach is seated behind the principal at the Sound of Music play finale. He is wearing a brown suit, has a cervical collar from his injury, and is behind a woman in a green sweater. A few minutes later, when the principal is talking to Vin Diesel about the wrestling coach finding a new calling, we see the coach on stage dressed as a nun, singing and taking bows. The camera then takes one last shot of the audience standing up and we see the very tall coach figure in the rear of the crowd, minus his collar. Brad Garrett's figure is an unmistakable one due to his size.
