In 1973, MGM released a strange little film called Wicked, Wicked about a psychopath stalking the female guests at a hotel. It was a precursor to the Halloween and Friday the 13th movies that were to come but it was filmed in a split screen process called Duo-Vision. One side tracked the killer and the other his victims or Detective David Bailey trying to catch him. The movie also starred Fantasy Femme Diane McBain, Tiffany Bolling, and Edd Byrnes. It was directed by the guy who directed numerous Green Acres episodes. Check out the trailer on YouTube. It looks just awful!
