This creepy sequel to 'House of Frankenstein', has a doctor (Onslow Stevens) trying to revive the monsters (Glenn Strange and Lon Chaney, Jr.) after becoming infected with the blood of Dracula.
All the atmospheric effects are present and there's a chilling performance by John Carradine whose gaunt appearance makes him a perfect choice for the Dracula part. The special effects involving his transformation are smoothly handled, as of course are the Wolfman's makeup change under the full moon. By this time, Universal had perfected many of these techniques and the effects are sometimes startlingly realistic. Lionel Atwill has a brief part as the village police chief and Martha O'Driscoll and Jane Adams provide the feminine interest.
But the main honors go to Onslow Stevens as the doctor who mistakenly inherits vampire tendencies--a sort of Dr. Jekyll and Mr. Hyde role that he does extremely well. A fright film that doesn't disappoint, entertaining all the way.
