First of all, this is a VERY difficult film to find in any condition, and I am afraid my endeavours obtained a print put out by Video Search of Miami that was grainy, subtitled in German(odd for a Spanish film), and rather bleary through much of it. I searched long for this print, and despite its many flaws, both with the copy and with the film, I must say that I enjoyed the film overall. It has very high marks for atmosphere with its superb European gothic castle and its slyvan night settings. The acting is pedestrian at best, and the plot about an ancient family curse of lycanthropy is somewhat muddled. Apparently an old family, suitably called Wolfstein, was populated with a werewolf named Imre Wolfstein. Some traveling gypsies come by the deserted castle and steal jewels from the dead family members in the vault, even taking the silver-pointed crucifix embedded in the body of Imre. Of course, this allows Imre to come back to life and rid the castle of those pesky gypsies and other villagers. In the wake of his feeding, he bites Waldemar Daninsky. The story really starts here as Waldemar and friends try to rid him of his new affliction. Thinking they are getting expert medical help, his friends enlist the aid of two vampires, who are up to no good. As you can see the plot has something for everyone. Well the film has lots going against it, but the atmospheric mood and settings, and the fact that this is the first of the eight Waldemar Daninsky films starring Paul Naschy are reason enough to grab some popcorn, light some candles, and sit back and enjoy some hokum.
