 FACT: On a few occasions in the film, whenever somebody is shot with  a pistol or a rifle, like in most action films they fly back several  feet. However this is impossible. Every action has an equal and  opposite reaction, so if the shot was powerful enough to send the  victim flying several feet through the air then theoretically the  blast would be powerful enough to send the person who shot the round  flying backwards several feet too. Realistically if a person is  shot, they would simply fall over or stumble.
