The October Project 2: Day 4

"You will not be saved by the holy ghost. You will not be saved by the god Plutonium. In fact, YOU WILL NOT BE SAVED!"

Prince of Darkness  (1987)
Directed by John Carpenter

John Carpenter was on some kind of a roll in the 80's. He gave us, amongst others, "Escape from New York", "The Thing", "Big Trouble in Little China", "They Live" and this one-of-a-kind horror classic.
A weird priest, played by Donald Pleasence, recruits a physics Professor and a group of grad students to investigate a strange find in the basement of an abandoned church. It turns out to be an impossibly ancient cylinder of swirling green liquid the origin of which I wouldn't dream of divulging here. What I will say (and I hope you find this sufficiently fascinating) is that this is the only film I know that posits the existence of Satan at a quantum level. Huh? Pretty cool right?

Also, Alice Cooper straight-up murders a guy with a bike frame.
Seriously.
