Continuity mistake: When the girls figure out that Knox is after Charlie, and Dylan thinks of the picture and they zoom in onto "Townsend." The shot before the final shot of the photograph shows Knox's father's arm around Charlie, when in all the other shots, he has his arms above his head. (01:00:05)
Continuity mistake: When Adam pounds on Zep with the toilet seat, he grabs his shoulder in pain. In the first shot of him holding his shoulder, his hand is soaked in blood. In the second shot, however, his hand is much cleaner. (01:30:25)
Visible crew/equipment: When the guy on the roof stands and takes aim at the window in preparation for Brian, the film crew are reflected in a window behind him. (00:13:00)
Visible crew/equipment: In the scene during the American bandstand, at the end of the song when the teacher is dancing in front of the band members, the crews can be seen. The dressing and the hair doesn't match Grease era at all, and someone is sitting on a director's chair as well. (01:06:20)
Continuity mistake: When the statue of Liberty is about to crash on the street, a close shot is seen of jammed cars and hysterical people. When the shot changes to Superman flying to the rescue, the jam, the cops and the people have disappeared, and all is nice and quiet in Metropolis.
Continuity mistake: When Maya enters Peter's office for the first time, you can see that he had just written something on his laptop. While they talk, you can see the word-program on the computer screen: it shows one page. Cut to Maya, then back to Peter: it shows two pages. Another cut: one page. This happens two or three times throughout the scene. (00:29:30)
Continuity mistake: In the opening scenes where the are driving home and the right front tire goes flat. Just before the Big rig truck hits them you can see that the tire is not flat. (00:07:50)
Other mistake: When Nick is in the spoon, the milk around him turns green.
Continuity mistake: In the fight between Barkis and Victor in the church, Victor slashes at Barkis with the fork and leaves 3 very noticable tears in Barkis' jacket. These tears aren't seen in any of the subsequent shots. (01:09:15)
Visible crew/equipment: When Benedict snaps his fingers and the dogs form a pyramid to show how well they are trained - look at the dog's feet and you can see the rails that the dogs are standing on. (00:43:50)
Continuity mistake: When Carly locks herself in the truck, the owner throws to the ground the box holding the fan belt and a few other things, right beside the driver's side of the truck. In the next exterior shot, there is nothing on the ground. (00:50:50)
Continuity mistake: When Snake kills the wrestler he falls forward shoulders forward, next minute his arms are over the ropes, next minute his arms are in a different position again - quite active for a dead man. (01:16:55 - 01:18:10)
Visible crew/equipment: As the villagers are running away from Kong, when the mother rescues the young child, in the next shot look to the back right side of the screen. A member of this movie's production crew steps into the shot, stands there watching as the movie extras are running, and the shot cuts away. (01:17:29)
Continuity mistake: After Heather is campaigning in the hallway of the school and giving out flyers, Buffy grabs the flyer and lets go of it, and is holding nothing. In the next scene where Buffy, Brenda and Cindy walk over to their boyfriends, Buffy all of a sudden has a folder, some books and a banana in one hand. (00:11:45)
Continuity mistake: When the Griswolds are driving to the tree farm, they are being harassed by the rednecks in the truck. Several shots of the front of the truck show only two passengers, but one view of the truck through its rear window shows three passengers. (00:04:17)
Continuity mistake: When Lasky heads toward the conning tower, an A-7 Corsair is shown at left (and the helicopter nose has a number "3" on it). As he is led inside the tower, the camera pans up, and now the Corsair is gone, replaced by an E-2 Hawkeye (and the number "3" on the heli is gone, too). (00:06:45)
Continuity mistake: After the Bandit jumps the bridge Sheriff Justice rear-ends the cop car in front of him, smashing the hood of his car. In the next scene Sheriff Justice's hood is fine.
Revealing mistake: Joe is much too old to be in high school. He appears to be in his thirties (the actor playing him was 35 at the time).
Continuity mistake: The scar on the Duke's bodyguard's face switches from one cheek to the other throughout the movie, due to flipped shots. (00:17:30)
Revealing mistake: There's one scene where they are surrounded by the foot. Leonardo reaches behind him for his katanas, but he doesn't unsheath them. If you look at his elbows, you can see gaps in the pads where the actor in the suit hasn't fully fastened the gloves to the rest of the outfit. (01:05:40)
