Character mistake: Near the end, just before Derek and Danny depart at Danny's high school, Derek says to his brother "I saw a car cruising by the house last night when I pulled out of there with Seth." The car that was shown driving by their house the previous night was in a brief scene right after Derek and Danny took down all of their nazi posters, and before Derek took a shower. He had not just 'pulled out of there with Seth.' The last time he had seen Seth at this point in the movie was at Cameron's party where Seth had almost shot him.
Continuity mistake: 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.
Derek Vinyard: Alright listen up, we need to open our eyes. There's over two million illegal immigrants bending down in this state tonight. This state spend three billion dollars last year on services, on people who had no right to be here in the first place. Three billion dollars. 400 million just to lock up a bunch of illegal immigrant criminals who only got in this country because the fucking INS decided it's not worth the effort to screen for convicted felons.
Trivia: The ending was originally different. After the scene where Derek is crying over Danny, it cut to Henry being arrested, then his family in the kitchen mourning him and saying he was a good boy, and then Derek shaving his head again while smiling. When Edward Norton read the script, he said "I thought the movie was supposed to be anti-Nazi." So the ending was soon changed.MikeH
