Cat-fearing Bela Lugosi pursues devil-worshipping Boris Karloff through his crazed, Bauhaus-on-acid mansion, sitting atop the bodies of thousands of WW I vets.

Boris Karloff gives one of his finest performances as the 3,000-year-old Egyptian who returns from the dead to reclaim reincarnated love Zita Johann, in cinematographer-turned-director Karl Freund’s marvelously atmospheric chiller - easily the best of many mummy films to come.

In this atmospheric and underrated mystery, three suitors converge on a castle to seek the hand of a young woman (Gloria Stuart). There’s a door at the estate that has been locked for many years; when asked about it, the girl’s father (Lionel Atwill) explains that the blue room was the scene of three strange deaths. In a show of bravery, the young men each volunteer to spend a night there – but they don’t all make it to the morning.
