The Legend of Hell House

The Legend of Hell House is a 1973 British horror film directed by John Hough and based on the American 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 physicists and parapsychologists who spend a week in a purportedly haunted English manor in which previous investigators were killed while doing research.

Accompanying Barrett are his wife, Ann, as well as two mediums a mental medium and Spiritualist minister, Florence Tanner, and a physical medium, Ben Fischer, who is also the only one of an earlier investigation to escape undamaged in mind or body. The rationalist Barrett is rudely sceptical of Tanners 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 any paranormal presence or force.Though not a physical medium, Tanner begins to manifest physical phenomena inside the house. When, after a quarrel with Tanner, Barrett is attacked by invisible forces, he suspects that Tanner may be using the houses energy against him. Meanwhile, Fischer remains aloof, with his mind closed to the houses influence, and is only there to collect the generous pay offered him to return. ........
