According to The Hollywood Reporter, Gigandet will be playing a young wasteland sheriff who is part vampire. (I'm never sure how this works. To me, being a vampire is like being dead or pregnant -- there's no in-between.) He partners up with Ivan Isaacs (the titular priest) in order to find Isaacs' niece, who just happens to be the girl he loves. She's been kidnapped by vampires, the latest casualty of a battle between man and vampire that has raged for centuries.
Priest is based on Hyung Min-woo's popular manga series, and will be directed by Scott Stewart. Though Cory Goodman's script has reportedly changed things quite a bit, one thing it is keeping is the Western / horror setting, which intrigues me, even if my girlish curiosity does make me long for its old cast and Sam Raimi as producer. But hey, at least it's set to finally happen. All they need now is the niece, and a few bad vampires to set against Gigandet and Bettany. Say, is Michael Sheen available?
