The Last Exorcism: best viral ever?

This is the best viral advertising idea I've ever seen. If you've visited Chat Roulette, you'll know that it's a free site where strangers with webcams are randomly connected to each other. Usually this means a lot of nudity and masturbation from single men, and nothing much else of interest. But to advertise their movie The Last Exorcism, Lionsgate had the superb idea of playing a pre-recorded video of a sexy teenage girl, who looks like she's about to expose her breasts, but who ends up being possessed by a demon! And now Lionsgate have uploaded some of the best reactions their little viral has elicited from unsuspecting Chat Rouletters. I hope there's more to come, before the viral itself becomes too well-known. Enjoy!
