Say what you will about Paul Bettany's slice-em-up vampire Western Priest, we're sluts for interesting world-building. And this new trailer has heaps of it. Watch how the Church changed the vampire-besieged world forever!

Gotta love the prison cell computer-generated confessional. As long as they keep fleshing out this dark new holy land, we'll continue to follow Priest into the vampire-packed desert. Slow-motion vampire fist bump!

Priest hits theaters May 13th.
