Roger Corman directing the like of Vincent Price and Lon Chaney Jr, in a movie inspired by Lovecraft's The Strange case of Charles Dexter Ward (the movie itself have just the title took from Edgar Allan Poe, taken from one of his poem inside "The Fall of the House of Usher"). Even before watching it I was sensing something great, and indeed it is.
Even more than 50 years later the movie is still great, with its gloomy atmosphere and fantastic photography. Oh, and Price's performance!! Masterpiece
