It is the rudest thing to talk out loud, use your phone or snack excessively loud when watching a movie in a cinema. You're ruining the experience for everyone! Coca-Cola decided to create a fake movie trailer featuring people in the actual theater disrupting the action on screen to drive home a point of "When you make noise during the movie, you become part of it," Watch it after the jump!

They used a hidden camera in the lobby, and unsuspecting patrons were filmed and immediately composited into a fake trailer serving as a PSA reminding the audience to be polite and respect others while watching a movie. Is this movie-shaming?

This will guarantee a very attentive audience for sure.
