What would YOU do if you stumbled upon someone being murdered... Run? Scream? Go after the perp? Take a photo or video? This elevator experiment was put on by Thinkmodo in promotion of Colin Farrell's new movie, Dead Man Down that opens tomorrow. I think it's more than effective marketing but not necessarily for the movie, try a lesson in ethics for us all instead. The reaction of nearly everyone that accidentally saw the 'murder' is absolutely appalling. As for the actors, it's a miracle though that nobody walked up to the elevator with a concealed weapon...
