Audio problem: When the crowd is gathering around Cliff after he falls from the balcony, you can hear a lot of the same background dialog being looped over and over. Some of the easier ones to spot are guys yelling "Right there, man." and "Where is it?" and a girl yelling "Stop." Those three can be heard distinctly at least three times.
Audio problem: In the high speed chase scene, Cliff pulls a gun out of the glove box and fires several rounds at the police, which showed a bright muzzle flash. We hear Cliff fire another barrage of shots out the window, but he is not pulling the trigger, and there is no muzzle flash.
