If The Last Exorcism's Rev. Cotton Marcus had stopped at 47 exorcisms, we wouldn't have a movie. Or this creepy poster. Luckily, he had to perform just one more. (But then they always do, right?)

The movie, directed by Daniel Stamm and produced by Eli Roth, is about an exorcist (portrayed by Patrick Fabian) who's spent his life bilking true believers. Tortured by a lifetime of deceit, he decides to let a documentary film crew follow him for one final exorcism, during which he plans to confess.

But as you might guess, things don't go quite as planned ...

The Last Exorcism, which also stars Ashley Bell and Iris Bahr, opens Aug. 27.

Check out the eerie new poster below.
