Now this is one brilliant piece of viral marketing! For those of you who don’t know, The Last Exorcism is a film produced by Eli Roth (of Hostel fame) and shot in the phony-documentary style of films like The Blair Witch Project, Cloverfield, and The Poughkeepsie Tapes. It is the story of a documentary film crew who follows reverand Cotton Marcus as he prepares to perform the last exorcism of his career. Naturally, what Marcus and his film crew encounter is nothing they could have anticipated. Much like the people in the video above!
