Continuity mistake: When Marvin is trying to get money to pay off the speeding ticket, Bobby reaches into his pocket with his left hand and takes the cigarette out of his mouth with his right hand. Both hands are in motion as this shot ends. The shot then switches to another angle, and Bobby now has the cigarette in his left hand, both arms already at his sides. There was no time to complete this move between shots.
Continuity mistake: In the opening sequence, where the three brothers are fighting, the father comes in to stop them, and there is a shot of all three brothers on the floor. No one has any injuries, but when it cuts to a close-up of Buddy, he has a bloody nose.
