So that "Office Berserker" video we linked to last week—security camera footage purportedly showing a man going crazy at work and destroying his entire office, along with many of his coworkers—has been confirmed as another freaking viral marketing video (as suspected). This time the prankster was a Russian director trying to build buzz for a film called Wanted. Damn you, Timur Bekmambetov! It's getting to where you just can't trust online footage of unprovoked violence any more. If you care to, watch the clip again with a more jaundiced eye, after the jump.
