Murders in the Rue Morgue is a 1932 horror film, loosely based on Edgar Allan Poe’s short story “The Murders in the Rue Morgue”. Bela Lugosi (one year after his performance as Dracula) portrays a lunatic scientist who abducts women and injects them with blood from his ill-tempered caged ape. Karl Freund’s cinematography and Robert Florey’s direction have been praised by critics and characterized as “expressionistic” by Leonard Maltin.[2] Despite the film being pre-Code, violent sequences prompted Universal to cut its running time from 80 minutes to 61 minutes.
