How did we wind up with a post-apocalyptic world where the church is our only defence against vampires? Watch this amazing animation prequel by Genndy Tartakovsky (Samurai Jack) that explains the bloody vampire vs. human history of Priest.

This short film first screened last weekend at the Priest panel at Wondercon, with director Scott Stewart and star Paul Bettany. Priest, loosely based on the graphic novel by Min-Woo Hyung will be in theaters May 13th.
