Edgar Allan Poe wouldn’t recognize his story, which drops everything but the gorilla killer and the title, completely changes the characters, motives and developments, and is sexed up to the limit. In place of the cool detective whose calculating method was the model for the Sherlock Holmeses and Arsene Lupins that followed, this version’s hero is a young medical student who mixes romance with science.
The cast’s other scientist, a loony Dr Mirakle played in Bela Lugosi’s customary fantastic manner, is an evolution bug who seeks to prove a vague fact by mixing the blood of his captive gorilla with that of Parisian women. The murders # three real and one almost # are results of his fiendish transfusions.
First meeting of the young medico and his sweetheart with Dr Mirakle and his caged gorilla occurs at the doc’s side show. The brute snatches the girl’s bonnet and from then on by intimation it’s shown that the gorilla desires her.
The real threat is the constant possiblity of the gorilla capturing the girl. Sidney Fox overdraws the sweet ingenue to the point of nearly distracting an audience from any fear it might have for her.
