This movie is an early horror film classic and certainly one that a well-rounded horror movie aficionado should not miss. An invalid concert pianist dies, leaving a will that does not include his personal secretary Hilary Cummins (Peter Lorre) as a beneficiary. Furious, the left-out yes-man cuts off a hand from the corpse and plots revenge. Unfortunately for Hilary, the hand inherits a life of its own and relentlessly stalks the wild-eyed Lorre as he flees in vain. Special effects keep the audience jumping as they dread the next appearance of this gruesome walking hand. The film is directed by Robert Florey, who also directed Murders in the Rue Morgue (1932).
