Baron Blood
After spending several years exploring more contemporary genres, director Mario Bava (Black Sunday) returned with Baron Blood to the Gothic world as a setting for a gruesome thriller. Working with producer Alfredo Leone, Bava crafted a film that is loyal to the bylaws of traditional horror, but is infused with a more modern visual style.
An American professor (Antonio Cantafora) travels to the estate of his ancestor, the sadistic Baron Otto von Kleist, seeking the truth beneath his notorious reputation. When he and his assistant Eva (Elke Sommer) read aloud an ancient incantation, the Baron's spirit is resurrected, leading to a series of violent deaths within the haunted castle.
Special Features:
High Definition Blu-ray (1080p) and Standard Definition DVD presentation of three versions of the film: Bava's original version Gli orrori del castello di Norimberga with Italian audio, The European Export Version of Baron Bloodwith English audio, and, on home video for the first time, the re-edited and re-dubbed AIP Version of Baron Blood with alternate score by Les Baxter.
