About Priest

Priest is a 2011 American action horror film directed by Scott Stewart, written by Cory Goodman, and starring Paul Bettany as the title character. It is loosely based on the Korean comic of the same name by Hyung Min-woo, in turn inspired by the computer game Blood by Monolith Productions. Set in an alternate universe where humanity and vampires have warred for centuries, after the last Vampire War, a veteran Warrior Priest lives in obscurity until his niece is kidnapped by vampires.
