Colin Farrell's new movie "Dead Man Down" opens this Friday and the promoters did something very unusual to promote the film in the form of a prank. The prank involved real people getting onto an elevator in New York City and seeing what appeared to be a murder in progress. When the elevator doors opened, unsuspecting citizens would see a guy strangling another guy with a rope. Some ran away screaming, some stood frozen, some actually tried to help the victim by stopping it - one guy paused to take a picture with his phone.

As funny as some of the reactions are, I think some were set-ups, but the good news is you can judge for yourself. What would you have done?
