Check out the new trailer for Priest starring Paul Bettany as a vampire-killing warrior priest. The film follows a priest who lives in a walled-in city that holds some of the last remnants of humankind.  

Bettany plays the priest who fought and destroyed the vampires, which is the reason the humans are living in these isolated cities.

He must fight a new wave of vampires when he learns they have taken his niece hostage.

Priest, directed by Scott Steward, also stars Cam Gigandet and Maggie Q.

The film hits theaters in 3-D on May 13, 2011.
