House on Haunted Hill is a 1959 American horror film. It was directed by William Castle, written by Robb White and stars Vincent Price as eccentric millionaire Frederick Loren. He and his fourth wife, Annabelle, have invited five people to the house for a "haunted house" party. Whoever stays in the house for one night will earn $10,000. As the night progresses, all the guests are trapped inside the house with ghosts, murderers, and other terrors.
Exterior shots of the house were filmed at the historic Ennis House in Los Feliz, California.
Eccentric millionaire Frederick Loren (Vincent Price) invites five people to a "party" he is throwing for his fourth wife, Annabelle (Carol Ohmart), in an allegedly haunted house he has rented, promising to give them each $10,000 with the stipulation that they must stay the entire night in the house after the doors are locked at midnight. The five guests are test pilot Lance Schroeder (Richard Long), newspaper columnist Ruth Bridges (Julie Mitchum), psychiatrist Dr. David Trent (Alan Marshal) who specializes in hysteria, Nora Manning (Carolyn Craig), who works for one of Loren's companies, and the house's owner Watson Pritchard (Elisha Cook). Pritchard disapproves of Loren's use of the house for his "party," making it unclear how Loren acquired access to the house in the first place.
Arriving late at night in separate funeral cars with a hearse leading the procession, Loren's guests are told the rules of the party, and each is given a .45 caliber pistol for protection. Forced to attend the party, Loren's wife tries to warn the guests that her husband is psychotic, causing them to be very suspicious of him. Nora becomes convinced that he's trying to kill her when she keeps seeing frightening apparitions, including the ghost of Annabelle, who had apparently hanged herself some time during the night.
Almost as frightened as Nora is Watson Pritchard. He is convinced that the house is genuinely haunted by the ghosts of those killed there in the past, including his own brother, and that those ghosts have the power to "come for" (kill) anyone in the house. Schroeder is attacked in a basement room, but is convinced his attacker was real, and tries to calm Nora's fears.
