Bela Lugosi appeared in several of these low budget chillers for Monogram Studios in the 1940's and The Corpse Vanishes is one of the better ones.
Bela plays a mad scientist who kidnaps young brides and kills them and then extracts fluid from their bodies so he can keep his ageing wife looking young. After a reporter and a doctor stay the night at his home and discover he is responsible for the brides' deaths, the following morning they report these murders to the police and the mad scientist is shot and drops dead shortly afterwards.
You have got almost everything in this movie: the scientist's assistants consist of an old hag, a hunchback and dwarf (her sons), a thunderstorm and spooky passages in Bela's house. Bela and his wife find they sleep better in coffins rather than beds in the movie.
The Corpse Vanishes is worth a look, especially for Bela Lugosi fans. Great fun.
Rating: 3 stars out of 5.
