Have you seen this viral video about a murder attempt taking place taking place in an elevator? As a marketing stunt for a new action thriller movie, Dead Man Down, the production company staged a mock murder-in-progress in a New York City elevator and films the reactions of unsuspecting people trying to board. It is quite interesting to see the different responses. Some people run, scream, call 911 and some actually attempt to stop the crime. What would you do? Let us know by posting a comment.
