Clive Barker was working really hard early on in his career to take Stephen King's horror throne, and had a string of great books and movies. Hellraiser was just the first great movie, but one of my favorites that often gets overlooked is a really creepy flick with Scott Bakula from Quantum Leap.

Lord of Illusions (1995)

Aside from having a great line from the bad guy, "I was born to murder the world." this movie has some really haunting images in it, like the mostly unseen exorcism that the Harry keeps flashing back to that has scarred him. It also features the Über-hot Famke Janssen in it, and the not-hot Kevin J. O'Connor, who you probably don't know by name, but will recognize when you see him.
