Yep. That's Dane Cook. With blood on him. He stars along with Josh Hutcherson ("The Kids Are All Right") in director Joseph Khan's "Detention." Described as a horror comedy with a little bit of time travel and John Hughes films mixed in, "Detention" focuses on a group of high school seniors who are stuck in detention on prom night. And as luck would have it, a serial killer from a slasher movie has come to life to terrorize the teens. "Detention" is scheduled for release on July 21, 2011 by Universal Pictures in (surprise, surprise!) 3D.
