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 (Lily Collins) is kidnapped by vampires.

The film was released on May 13, 2011. The film earned over $78 million at the box office against a $60 million production budget, but it was panned by critics, who praised the film's visual style and art direction while criticizing the movie's use of genre clichés, writing, acting, editing, and action scenes.
