There are 2 versions of the film -one was reconstructed from an incomplete and partially decomposed print and the more recent DVD version was made from an excellent print found in the BFI archives.
The New York Times review at the time said, "A newsreel of a Sunday school picnic would have been more thrilling." 1000 Misspent Hours calls it "one of the better horror films of its era, regardless of nationality". There's nothing like a difference of opinion, and what a difference! It's hard for me to find fault with Karloff, since his Mummy is so brilliant, and this bears a couple of poor-relation similarities to that classic. Moria says, "Despite the film’s creakiness, an undeniable atmosphere does come through."
