This house – it knows we’re here. Elderly millionaire Rudolf Deutsch (Roland Culver) is obsessed with the afterlife and hires sceptical scientist Lionel Barrett (Clive Revill) and his wife Ann (Gayle Hunnicutt) to lead a team into the infamous Belasco House, supposedly haunted by the victims of its late owner, a notorious six-foot five serial killer. Though the rational Barrett does not believe in ghosts, the other members of his group ding, including devout spiritualist Florence Tanner (Pamela Franklin) and psychic medium Benjamin Fischer (Roddy McDowall), who has been in Belasco House before and is the only survivor of a previous visit and has therefore seen what horrors can befall those who enter it... The house tried to kill me – it almost succeeded. Fabled novelist and screenwriter Richard Matheson adapted his own Hell House and transposed it from New England to the old country for financial reasons where it was directed by John Hough (who would also direct the cult Disney horror Watcher in the Woods there a half-dozen years later). This pits science and the rational against the paranormal, with fascinating excursions into the psychosexual – it ain’t too often you see a ghost having its way with a young lady. And Franklin’s presence, a dozen years after that spectacular classic of a haunting, The Innocents, is a guarantee of this film’s integrity and she rewards us with a dazzling performance. Hunnicutt is no less effective although her eroticism is literally in another kind of dimension. Frankly any film that commences with the following statement has me at hello: Although the story of this film is fictitious, the events depicted involving psychic phenomena are not only very much within the bounds of possibility, but could well be true (Tom Corbett, Clairvoyant and Psychic Consultant to European Royalty). The building’s negative energy has amazing repercussions for these investigators and McDowall has one of his best roles as an unlikely hero, with an unbilled cameo by one of Brit horror/exploitation’s key actors rounding things out as things end rather explosively but paradoxically, giving this a very human affect in a story of things unseen and the detritus of perversion. One of the very best horror films of the Seventies, probably inspired by Aleister Crowley. Shot at Bolney, West Sussex, Blenheim Palace and Elstree Studios. If you’re that clever why are you still a prisoner in this house?
