The Exorcist III (1990)

Eschewing the campy histrionics of the disastrous (albeit guiltily enjoyable) first sequel, William Peter Blatty’s inspired adaptation of his own novel Legion stars George C Scott as a police lieutenant investigating a series of suspected satanic murders. Criminally overlooked at the time of release, this creeping masterclass in atmosphere now stands as one of the most frightening horror films of the 90s.
