Thanks to Yahoo! Movies, we now have the debut trailer for The Last Exorcism. The horror film follows evangelical minister Marcus Cotton (Patrick Fabian), who has performed religious rites he did not believe in for years. Before quitting the business for good, he agrees to let a documentary crew film his last exorcism of a possessed girl (Ashley Bell) to the desperate pleas of her father. Needless to say, things don’t go as planned.
