Scream of the Demon Lover (released in Italy as Il castello dalle porte di fuoco/ The Castle With the Door of Fire) is a Spanish-Italian horror film, originally written under the title Ivanna. It was released in France as Le Monstre du château, and in Mexico as El Castillo di Frankestein. It was written by Enrico Colombo and Maria del Carmen Martinez Roman, with input from the director Jose Luis Merino. Roger Corman bought the film for his New World Pictures to put on a drive-in double bill with The Velvet Vampire. The film was cut in the U.S. from 98 minutes to only 78 minutes, eliminating some of the nudity/ gore.
Plot
A beautiful young woman named Ivanna travels to a remote estate to seek employment as a biochemist for Baron Janos Dalmar. She finds herself attracted to him, so she immerses herself in her work to suppress her lusty desires. A rash of rather brutal murders occurs in the area, and she soon discovers that the Baron is not what he seems. Not long thereafter, the Baron transforms into a demon, and the beautiful young woman becomes his personal love slave.
