INVISIBLE GHOST (1941) Lugosi in a great poverty row flick. He is obsessed with his "dead" wife and develops a split personality. From kindly doctor, to insane murderer, Lugosi's hystronics and intensity are a sight to behold. Some cool under lighting adds a bit more class to this low budget entry.
Also on this DVD: THE CORPSE VANISHES (1942) A Lugosi poverty row fave. Bela is using the blood of young woman to keep his wife youthful. Dreadfully delightful, with Lugosi giving it his all.
