The handsome Baron Janos Dalmar is believed to be a homicidal maniac who rapes the girls he lures to his castle before feeding the bodies to his monstrous dogs. Still, these are just rumors nobody can prove. Dalmar then recruits the beautiful and intelligent female chemist Ivanna and, through her dreams, she discovers that there are much deeper secrets hidden behind the castle's walls. "Blood Castle" is mediocre Gothic horror with a lot of routine plotting and only one or two really ingenious moments. The castle setting is terrific, though, and the make up effects on the actual murderer are quite eerie and convincing. The lead actress drivels way too much and she doesn't only seem to bore her male counterpart but also us; viewers. All the clichés are there, with the beast in the cellar, the ominous servants and the superstitious villagers who only just survived a plague-epidemic. This film is watchable enough, but there are many other Gothic horror classics available, so you don't really need to waste your time on this average installment. The better choices include "The Virgin of Nuremberg", "The Whip and the Body", "Nightmare Castle", "Baron Blood" and "Danse Macabre".
