The Legend of Hell House  The Legend of Hell House is a 1973 British supernatural horror film directed by John Hough and based on the novel "Hell House" by Richard Matheson, who also wrote the screenplay. The film stars Pamela Franklin, Roddy McDowall, Clive Revill, and Gayle Hunnicutt as a group of researchers who spend a week in a purportedly haunted English mansion in which previous investigators were killed. The physicist Dr. Lionel Barrett is enlisted by eccentric millionaire Mr. Deutsch to make an investigation into "survival after death" in "the one place where it has yet to be refuted". This is Belasco House, the "Mount Everest of haunted houses", originally owned by the notorious "Roaring Giant" Emeric Belasco, a six-foot-five perverted millionaire and supposed murderer, who disappeared soon after a massacre at his home. The house is believed to be haunted by numerous spirits, the victims of Belasco's twisted and sadistic desires. Accompanying Barrett are his wife, Ann, as well as two mediums: mental medium and spiritualist minister Florence Tanner and physical medium Benjamin Franklin "Ben" Fischer, who is the only survivor of an investigation conducted 20 years before. The group arrive to begin their investigation a week before Christmas Eve, and the rationalist Barrett is rudely skeptical of Florence's belief in "surviving personalities", spirits which haunt the physical world, and he asserts that there is nothing but unfocused electromagnetic energy in the house. Barrett brings a machine he has developed, which he believes will rid the house of this energy. Though not a physical medium, Florence begins to manifest physical phenomena inside the house. When, after a quarrel with Tanner, Barrett is attacked by invisible forces, he suspects that Florence may be using the house's energy against him. Meanwhile, Fischer remains aloof, with his mind closed to the house's influence, and is only there to collect the generous paycheck. Ann Barrett is subjected to erotic visions late at night, which seem linked to her lackluster sex life. She goes downstairs and, in an apparent trance, disrobes and demands sex from Fischer. He strikes her, snapping her out of the trance, and she returns to herself, horrified and ashamed. A second incident occurs a day or so later; this time, she is awake but uninhibited due to alcohol. Her husband arrives a moment later to witness her advances to Fischer. He is resentful, and spurns Fischer's warnings that the house is affecting Ann, claiming that "Mr. Deutsch is wasting one-third of his money!"
