When Jim, Pedro and Mickey steal the car to sell to Mickey's brother, Jim is smoking a cigarette which he takes a drag of then throws out the window. When Pedro nearly crashes the car he is smoking it again.
At the beginning of the movie, just after the by was beaten by the Father. They walked towards the door to leave dressed in their school uniforms and when they got to the other side of the door, they were are dressed in street clothes.
In the "dream" scene, when Jim is shooting his classmates, the one who gets shot in the back has a visible string attached to him which pulls him to the blackboard. When Jim has a vision on the basketball court and gets blown by explosion, the string is visible again. They were dream sequences, but it seems unlikely that he would dream of strings.
Although this movie is based on an autobiography of a person growing up in the 1960s, it appears that there has been no effort to portray that era in the movie. This is evidenced by the fashions, music, cars and backdrops used, none of which are from that era. The following items would be anachronisms if the movie were in fact set in the 1960s:
- 1) only modern-era vehicles seen in outdoor scenes;
- 2) numerous skyscrapers that didn't exist in background shots, including the Twin Towers;
- 3) modern medical equipment used to treat cancer;
- 4) Jim and Bobby are on post porn-littered 42nd Street and reminiscing about the time when the area was filled with adult businesses ... NYC mayor Giuliani had the district cleaned-up in the 1990's;
- 5) Bobby refers to one porn movie with the title, The Sperminator, an obvious take from the 1984 blockbuster, The Terminator;
- 6) A marquee sign in the background reports "Two US helicopters down over Iraq" in reference to the Gulf War in the early 1990's;
- 7) During the basketball game where Jim and Mickey are too high to play, there are championship banners dated 1976 and 1988.;
- 8) When the cops enter the ice cream store they are wearing 1990s style police uniforms.
When Jim is playing basketball and explaining how he plays and Pedro steals from the locker rooms, each time there is a point scored you can clearly hear the crowd cheering but visually the crowd is very calm.
