House Of The Long Shadows (1983)
Old-fashioned "haunted house" suspense drives this spooky adaptation of Earl Derr Biggers' book "Seven Keys to Baldpate." An American writer (Desi Arnaz, Jr.), who's made a bet that he can pen a novel in 24 hours, travels to a secluded Welsh manor where he's thrust into the center of a real-life whodunit, terrorized by a group of sinister characters portrayed by movie horror masters Vincent Price, Peter Cushing, Christopher Lee, and John Carradine. 106 min. Standard; Soundtrack: English Dolby Digital stereo.
