Wicked, Wicked (1973) A tongue-in-cheek psycho movie in "Duo-vision." The entire feature employs the split-screen technique used in parts of Brian De Palma's "Sisters" that same year. As a handyman at a seacoast hotel, Randolph Roberts wears a monster mask while he kills and dismembers women with blond hair. Tiffany Bolling is a singer, Scott Brady is a detective and Edd "Kookie" Burns is a lifeguard. The music is the original organ score for the silent film "Phantom of the Opera."
