Cup of My Blood (2005)

When a modern-day pornographer comes into possession of the Holy Grail, a non-stop attack by the forces of the damned threatens to unleash the Apocalypse in this religious-themed horror film from first-time filmmaker Lance Catania. Jack Fender (Daniel Patrick Sullivan) is a photographer who would rather be capturing tasteful nudes on film rather than the shooting the smut that pays the bills. When Jack inadvertently acquires one of the most sought after holy relics in the history of Christianity, his quest for answers lead him to the darkest corners of human existence. ~ Jason Buchanan, All Movie Guide
