Continuity mistake: In the scene where Hank comes crashing into the building with Dick's car, the driver's side headlight is intact. They show the people in the building, and when the shot returns to the car, the headlight is dangling from its socket. (00:21:00)
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 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: 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 Tom Hanks cuts his hand and loses his temper, he picks up the volleyball with a bloody hand and throws it. When he picks it up, you can see that his fingers are spread. When you see the handprint that he makes "Wilson" with, you can see that the fingerprints are together and parallel.
Continuity mistake: When Julia is trying to figure a way out the cell, she starting feeling around the edges of the glass panels etc., and she then comes to the end and stands by the green bench which is at the side of the cell. Julia's black heels sit on the bench, but then when Julia notices the pipe and climbs up to attempt to pull it, in the overhead shot her black heels have vanished from the bench. (01:08:40)Hamster
Continuity mistake: The tyres on the crotch rocket motorcycles they were riding kept changing from knobbly tyres to road slicks, back and forth depending on what terrain they were on. Easiest to see when Ethan skids on the road to avoid the white van - clear shot of slick tyres - then about 30 seconds later they're on the dirt, he skids into the old car and you can easily see that he's got off-road tyres front and back.
Continuity mistake: In the scene in the karaoke shop, watch the light through the window. Sometimes it's daylight outside, sometimes it's dark.
Continuity mistake: At the beginning "Pete" asks Violet for her autograph on a time card. She signs it and the "T" is not crossed, and when Pete puts it on the board it is crossed. Then at the end when Violet's dad buys it from Pete it is again not crossed. Also if you look at the "V" when she signs it and after Pete puts it up they are different. And lastly, when Violet signs her last name it is spaced but when Pete puts it up it is jumbled together. Her signature is different all around. (00:01:30 - 01:27:30)
Factual error: When Arnold is in the police station reporting that he has a clone and passes through a control room, one computer screen is flashing "OVERIDE." The correct spelling is "OVERRIDE." (00:38:05)
Continuity mistake: When Memphis is driving Eleanor he backs up and hits the right rear-view mirror. He stops, leans out the window and sees that it is dangling. The very next shot it is back to normal and it stays that way for most of the rest of the movie. (01:34:34)
