The Legend of Hell House (1973, John Hough)

Good house and one good character: Roddy McDowall as a jaded, buttoned-up medium refusing to let the spirits in. He and some others are sent by a rich guy to live in the definitely haunted house to prove the existence of an afterlife. Arrogant scientist Clive Revill (CHUD II: Bud the Chud) almost sinks the movie, but fortunately the house wins, and Roddy outlives Clive. Roddy’s fellow medium is Pamela Franklin (Food of the Gods, The Nanny), the first to die, and Clive’s long-suffering wife Gayle Hunnicutt (Eye of the Cat) is allowed to live. Roddy defeats the ghost by taunting it relentlessly, which seems a bad strategy, but don’t underestimate the British weakness against taunting. Written by Twilight Zone vet Richard Matheson. Hough has made his share of cult faves, and also a Howling sequel, which I’ve probably seen but the sequels were all so shitty I’ve never tried to straighten out which movie was which.
