The Legend of Hell House (1973)

A bunch of psychics are hired to "exorcise" (for lack of a better term) a house of its "ghosts." Two of the psychics are mediums, a spiritual medium and physical medium. The third psychic is a paranormal physicist who doesn't believe in spirits, just electromagnetic influence. Along for the ride is the physicist's wife. In classic haunted house fashion, things start going wrong and the house starts to fight back. Fun fact: the malevolent spirit Belasco who haunts Hell House shares his name with the demon who kidnapped Illyana Rasputin in 1980s Uncanny X-Men! Thanks, Chris Claremont!
