Continuity: When Danny gets shot at the end of the film, his paper flies out of his hand. But the very next shot of him shows that the paper is still in his hand being held over his head while he falls backwards. In one of the following shots the paper is back on the floor, but it's on the opposite side it should have been when it flew out of his hand. It's all shown in slow motion and it's very obvious.

Continuity: Toward the beginning, when the principal calls Danny into his office to discuss his Mein Kampf paper, he first glares at the Jewish teacher who exits the principal's office. As the teacher is walking past, the clock on the wall reads 8:10. But when the camera angle changes to show him walk around a corner, the same clock reads 8:20. Apparently it took him 10 minutes to turn the corner.

Visible crew/equipment: In a scene in the principal's office reflections of the crew can be seen in the bookcase glass.  A crewmember wearing headphones and holding the boom can be seen fairly clearly.

Continuity: After the shooting, when Derek is being arrested, he is on his knees and the cop behind him helps him to his feet. The cop wraps his right arm across Derek's chest, the camera then cuts to the angle from Danny's view, and its now the cop's left arm across Derek's chest when he gets to his feet.
