Teenage Exorcist (1991)
Oh, the horror. Ugh. Yet another cheap direct to video horror flick from the early '90's. This one written by Fred Olen Ray and directed by Grant Austin Waldman. It stars Brinke Stevens and Michael Berryman.
IMDB describes the movie "Diane, a repressed, neurotic grad student, moves into a cursed mansion and is possessed by the house's demonic master.Transformed into a raven-haired, leather and lingerie-clad seductress, Diane seeks a virgin sacrifice for her master while her sister, brother-in-law, a priest, and a pizza boy try to rescue her and avoid his wrath." It's basically a lowball, cheezeball riff on the exorcist genre, trying desperately to be funny. Mileage may vary.
What brought this to my attention was the appearance of fan favorite actor from the 1970's, Robert Quarry, playing Father McFerrin.
