I recently saw this inventive advertisement for The Last Exorcism, directed by Daniel Stamm and released at the end of August this year. It’s an innovative use of a relatively new form of social networking and, as you can see, is particularly frightening to those who expect nothing but reality when they log in. It fits nicely with a mockumentary that plays with the division between what is fiction and what is fact. Just as the cynical preacher Cotton Marcus (Patrick Fabian) tries to expose demonic possession as a hoax, only to discover that it’s an all too frightful reality, so too do the unsuspecting users of Chatroulette find that what terrified them so much because it poses as the everyday is, in fact, nothing more than an advert.
