In one of the scenes where they are driving down the road to the concert (after breaking the guy out of school), they do a circular shot going one by one to each guy in the car. At first, the guy in the jean jacket in the back seat is wearing his jacket, and the shot goes back up front. When the camera pans back to the guy next to him he is not wearing his jacket, and the shot goes up front...once the camera gets back to him again, his jacket is back!!
