Many people forget film is a multi-sensory experience.
As a result, sound is neglected. While watching an action movie, listen to the sound of someone getting punched in the face. Now go find your red headed step brother and hit him in the face. That's because the sound you heard in the movie was not the sound of a person getting hit in the face. When listening to someone get punched in the face in a movie, the sound was most likely made after the shooting by a sound foley artist.
