Priest is a 2011 American post-apocalyptic science fiction action film starring Paul Bettany as the title character. The film, directed by Scott Stewart, is based on the Korean comic of the same name. In an alternate world, humanity and vampires have warred for centuries. After the last Vampire War, the Catholic priest and veteran Warrior Priest (Bettany) lives in obscurity with other humans inside one of the Church's walled cities. When the Priest's niece (Lily Collins) is kidnapped by vampires, the Priest breaks his vows to hunt them down. He is accompanied by the niece's boyfriend (Cam Gigandet), who is a wasteland sheriff; and a former Warrior Priestess (Maggie Q). The film first entered development in 2005, when Screen Gems bought the spec script by Cory Goodman. In 2006 Andrew Douglas was attached to direct and Gerard Butler was attached to star. They were eventually replaced by Stewart and Bettany in 2009 and filming started in Los Angeles, California, later in the year. The film changed release dates numerous times throughout 2010 and 2011. It was especially pushed back from 2010 to 2011 to convert the film from 2D to 3D.
