Inner Sanctum is a 1991 crime erotic thriller film which stars Tanya Roberts, Margaux Hemingway, Joseph Bottoms and Valerie Wildman, and was written by Mark Thomas McGee and directed by Fred Olen Ray.

The film was made for $650,000 and was very successful, leading to Ray making a series of erotic thrillers."I didn't really know what an erotic thriller was when I did Inner Sanctum", admitted Ray later. "I watched Wild Orchid—fast-forwarded through it, actually—to see what was expected of me."
