Continuity mistake: After the fury fighters' meeting with John McEnroe Dave asks Buddy to talk to him in private. The go into the multi-purpose hall of the community center which has a stage on one side. In all wide shots and one close-up we see them talking in front of the stage, in all other close-ups in front of an inscription on the wall which is about 20 meters away.
Continuity mistake: After their encounter with the monks, Buddy and Dave speed off and come out onto a road. The first shot sees the whole car come onto the road, where there is a double unbroken line in the middle of it. The shot changes to Buddy and Dave in the car. Watch through the back windshield. The double unbroken line has turned into a single, broken line.
Continuity mistake: In the night after the first fury fighters' meeting Dave and Chuck sit in a bar. When Dave says that he wants to go back Chuck's cigarette is in his mouth. When the camera angle changes it's in his hand. A little later, when Chuck memorizes the chicks in the war frying his banana the hand with the cigarette changes from hanging down to pointing up in mid-sentence.
Continuity mistake: When Buddy and Dave drive to work Buddy pulls the brake on the bridge. Through the rear window you see cars skidding and jamming up right behind them. Then comes an areal shot where there are just two cars braking at a distance, but when it cuts back to the view from the front the jam is back.
Continuity mistake: After his first court case Dave goes to the Community Center where Buddy does anger treatment. When he picks up one of Buddy's books from a table there are some wooden chairs scattered in the background. In the next shot we see him from an upstairs landing, and there is now one wooden chair with its back directly at the table, and one white plastic chair where the wooden chairs were before.
