There has always been a rivalry between Boris Karloff and Bela Lugosi. This Collector's Set dedicates one disc each to the two terrifying actors. Lugosi is saluted in Joseph H. Lewis' THE INVISIBLE GHOST and one of his best-loved B-movies, THE CORPSE VANISHES. Boris Karloff is solving murder mysteries on his disc as MR. WONG, DETECTIVE and in the Wong classic, FATAL HOUR, both from director William Nigh. Four classic chillers.
