Towards the end of the movie, the main characters are in a car chase, heading towards a blockade. Officers at the blockade begin firing at the car, all from in front of the car. There is only one officer behind them, and he is clearly not shooting, just chasing them in his own car. However, when the camera shows the back of their car racing towards the blockade, several sparks (representing where bullets are hitting the car) are seen on the very back of the car. Since the shooters are all in front of the car, it would be impossible for the bullets to be sparking the very back.
