Dr Cadman saves the life of an old student, Ramsay, by giving him a drug nick named the "black sleep" prior to his going to the gallows. The drug simulates death and Ramsay is believed to have died before the hangman could have his way with him. Cadman revives Ramsay and has him help with his operations mapping the centers of the brain. Of course Cadman is mad, his desire to help his wife who is in a coma, has reduced him to using means that are less than savory. Tension mounts as Ramsay's good nature clashes with Cadman and the weird things that are going on in the house.
Somehow this little gem slipped under my radar and it wasn't until recently that I even knew this movie existed. With a cast that would be the delight of any classic horror movie fan (Basil Rathbone, Bela Lugosi,Lon Chaney, John Carradine, Tor Johnson, Akim Tamiroff) this is a one of those movies that they don't make any more. This is an odd mix of what you think of as classic horror and modern graphic visuals with a moody castle passageways and graphic brain operations and disfigured monsters. It walks that fine line of being link between the Universal style horror films of the 30's and 40's and the drive in monster fare of the 50's and 60's (it feels like a black and white version of the Hammer Frankenstein films or something like Blood of the Vampire) . Its a great deal of fun, and more than a tad creepy and tense since you really can't be sure whats going to happen next. In its way its a classic of its kind.
My only real complaint is that the casting of Lugosi, Johnson and Carradine is a bit misleading since Lugosi only has a few scenes as a mute butler, and Carradine and Johnson only show up in the final 15 minutes. They are really no more than cameos and don't deserve the high placement in the credits they receive.
Definitely high on my recommend list to anyone who likes classic style horror. This is a movie to search out and enjoy late on a rainy Saturday night.
