Prince of Darkness (1987) is a supernatural horror film directed by John Carpenter, centering on a group of quantum physics students who are invited by a priest to investigate a mysterious liquid found in an ancient monastery. As the team deciphers cryptic texts, they learn the liquid may be the physical embodiment of a sinister force. As strange occurrences begin to plague the group, they face mounting evidence that the liquid has far-reaching and catastrophic implications. Set within the eerie confines of the monastery, this slow-burning horror film builds suspense through its blend of science, religion, and the occult. The film is part of Carpenter's "Apocalypse Trilogy," a series that explores the collapse of human society through paranormal threats, and features strong performances from Donald Pleasence and Victor Wong.
