Great Fun!
11 January 1999 | by See all my reviews

This is a fun movie that is great at Halloween or any other time of year. While it is not the best known of any of the actors in it, it does have Bela Lugosi, Peter Lorre and Boris Karloff, where can you go wrong.

The jokes are a bit predictable but considering this film was made in 1940 it still is fun and even at times scary. Adding a bit of campiness to the classic horror genre of the time. I highly recommend it.
