Writer-director Scott Derrickson's paranormal crime thriller Deliver Us from Evil, opening soon, is based on the real-life experiences of retired N.Y.P.D. Sergeant Ralph Sarchie.  Eric Bana plays Sarchie in the upcoming film, but you can hear the real story from the demonologist himself in this new short video.  Take his words at face value or with a grain of salt; either way, Sarchie is certainly a character.  Now whether he's a disturbed individual in need of psychological help, a clever huckster, or something in between, I'll leave up to you to decide.

Deliver Us from Evil also stars Edgar Ramirez, Joel McHale, and Olivia Munn, and opens July 2nd.  Hit the jump to see Sarchie's story.

Watch Sarchie's tale below and be sure to see the highly dramatized version of it in Deliver Us from Evil on July 2nd:
