The House of Fear

An actor, John Woodford, dies on-stage during a performance of a play. His body is taken to his dressing room, where it disappears. The theatre is closed for over a year, and rumors that Woodford's ghost haunts it spread all over Broadway.

A detective (posing as a producer) rents the theatre and attempts to present the same play, but all sorts of "ghostly occurences" happen to try to thwart his plans. (Woodford's voice coming over a dead telephone, his face appearing on the pitch-dark stage during a police vigil, more murders, mysterious notes from the "dead man", etc).

All-in-all, a "different" mystery with good acting; if you watch the film intently, you can figure out who the murderer is (but, it's DIFFICULT!). Highly recommended. (btw....this film has NOTHING to do with the Sherlock Holmes film of the same name).
