Another bat-themed horror film, though somewhat more on the nose this time as it stars Bela “Dracula” Lugosi (as he was so often referred to in marketing of the time). Despite it’s ridiculous plot, the film is considered one of Lugosi’s better films for the so called “poverty row studios” that dominated his late career.
