Query: A little known, under-appreciated erotic thriller...

This movie is that rarity of rarities: an erotic film that is actually done well. Jena Bodner, in her first film role, delivers a credible performance as a woman undergoing a lycanthropic change and makes the movie worthwhile all on her own. Yes, she is nude every other scene, but you can hardly hold that against her. The castle setting, direction and cinematography all add a great deal to the production. My one complaint is that the ending is a bit inconclusive and up in the air, then, it looks like they were looking to make it into a series of films. The old British TV show "She-Wolf of London" might have done well to employ more of the primal, sexual themes used here. This is not one of the high art horror movies, like Dario Argento or Mario Bava, it is strictly exploitation, but it is well-done exploitation, and a pleasant surprise for a weekend night.
