A creepy film! Also a rare screen pairing of Bela Lugosi and Boris Karloff (billed only as "KARLOFF" for some reason).As the film opens, Bela is on his way to Karloff's mansion for a visit. On the train he meets a young couple and invites them to come along with him, which may be a mistake.
When we meet Karloff, we learn that is a creepy dude. First of all, he's a Satanist who reads "The Rites of Lucifer", and is preparing for a black moon ritual which may or not involve Bela and the couple, who try to escape.
Bela plays a good guy in this and wants to escape too, especially when he learns that Karloff has been keeping corpses in his basement, including one of his dead wife. Creepy! That's enough for anyone to want to get out of there. Bela is terrified of black cats, though and gets freaked out whenever one walks into the room, making it tough for him to leave.
According to my research, this was one of the top box office hits in 1934.
