Continuity mistake: When the fake ID is first seen in the movie, the back of the ID is blank white. But later on when it is seen again, the back of the ID has black print all over it. (00:24:15 - 00:40:20)
Continuity mistake: During the scene in which Evan and Seth first talk to Fogel about the fake I.D. several students are seen changing positions during shots. Most notably the white girl in a blue shirt standing in the backround between Evan and Seth being replaced by a black guy in an unrealistic time frame in between shots.
Factual error: When Fogle shoots the cop's pistol at the burning police car, the safety on the Smith and Wesson pistol is activated. He fires the weapon until it is empty and continues to dry fire (click) the pistol anyway. On the Smith and Wesson, the side levers are in Safe mode when pushed down. When the last round is fired, the slide locks back and the gun wouldn't be able to dry fire.
Deliberate mistake: When young Becca picks up the drawing that young Seth made, in the first shot, as she flips it over to look at it, you can faintly see the pen-marks through the paper, and they are not the same as in the following close-up shot, when we see the actual drawing. In the first shot, they seem to be a grouping of rectangular shapes, whereas in the second shot, it is obviously a large drawing of a penis. They had to use different pictures due to child labor laws that wouldn't permit the young actress from seeing the actual picture, and so a hand-double was used for the close-up shot. (00:17:15)
Continuity mistake: There is a scene where Evan, Seth and Fogell are discussing the list of liquor that Fogell is going to purchase while standing in front of the liquor store. Take notice of Fogell's left long sleeve shirt; it goes from being folded back enough to expose his wristwatch to being neatly folded down within several quick shots. (00:34:25 - 00:35:50)
Continuity mistake: After Evan, Seth and Fogell run from the two cops, the boys come to a bus stop, with a bus just pulling up to it. Take notice that there are about two passengers on the bus. Upon entering the bus, not only has the number of riders increased, but you also see the bum that you should have seen in the back of the bus (Fogell encountered earlier) from the previous shot when the bus arrived.
