Richard Matheson adapted the screenplay of The Legend of Hell House from his own novel. In the tradition of Shirley Jackson's Haunting of Hill House, four people with alleged extrasensory powers are called upon to spend a weekend in a supposedly haunted house, to either prove or disprove the presence of ghosts. Roddy McDowall has been in the house before, and refuses to treat the possibility of paranormal activity lightly; scientist Clive Revill believes that he can trace the happenings to rational explanations involving electric current; Pamela Franklin is convinced that, if spirits exists, she will be able to communicate with them; and Gayle Hunnicutt plays Revill's young wife, ripe for "possession." ~ Hal Erickson, Rovi
