As confident as Paul Naschy is in his self-assurance as an international horror star in the interview included with the DVD of this, I had never heard of him or his work. I don't say that in a negative or mocking way, but apparently he's a very famous Bela Lugosi-type in his home country but in today's horror market he doesn't even seem to be a footnote. It doesn't matter a whole lot really except to hardcore horror film fanatics like myself I guess. Werewolf Shadow (AKA Blood Moon, AKA The Werewolf VS. Vampire Woman, AKA Night of the Walpurgis) is apparently the fifth film in a Spanish werewolf series. I can't say that it's amazing or incredible. Most of its value comes from its unintentional comedy. It does have some atmosphere to it and some creepy visuals, but overall it doesn't hold up at all. At least to me.
