Continuity mistake: When Holland shows the bartender the dollar bill in the shape of a shirt, he is smoking a cigarette before he takes the cigarette out of his mouth. Holland mentions to the bartender that he made it himself, with nothing in his mouth, but in the next shot, the cigarette is suddenly back. (00:09:45)
Trivia: The corpse of Sid Shattuck, which Ryan Gosling discovers after his drunken roll down the hill, is played by an uncredited Robert Downey Jr., who'd previously starred in Shane Black's "Kiss Kiss Bang Bang", a film which played a large part in revitalising his career after drug and legal issues.
