The first trailer for the documentary The Devil and father Amorth has just been released, and it is extremely unsettling.

The movie is directed by William Friedkin, the filmmaker behind the horror classic, The Exorcist. But, what makes this one even scarier, is the fact that it’s not fictional.

The film follows the Vatican’s exorcist, Father Gabriele Amortha  and apparently shows him performing an actual exorcism. 

Obviously, some readers might find the footage disturbing.

The movie releases on April 20.
