Forget the preposterous plot and concentrate instead on Riccardo Freda's superlative direction and his sublime use of color and you have one of the great unsung horror films, Filmed in Italy with a largely Italian cast, (the leads are dubbed), it uses Poe as the jumping off point for an original screenplay by Ernesto Gastaldi as "The Horrible Dr. Hitchcock", (one of the film's several known titles), kills his first wife then tries to recreate the beauty of her resurrected corpse using the blood of wife #2, (Barbara Steele, who else!). It's nonsense, of course, but splendidly over-the-top nonsense that deserves to be better known.
