It is widely regarded that a Mr John Michael Osbourne (Ozzy to his friends) is the Prince of Darkness. This makes it all the more surprising that a Mr Vincent Damon Furnier (Alice Cooper to his friends) was cast as the gaunt, shuffling zombie in John Carpenter's 1987 film Prince of Darkness. The movie is about a vial containing the liquid essence of the son of Satan, and it deals with quantum physics, the nature of reality, the question of whether Jesus was an extra-terrestrial and finally what happens to your body if you drink the son of the devil. Spoiler. Turns out you melt. Not all the way, but most of the way.
