House On Haunted Hill

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 Fredrick 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 each. As the night progresses, all the guests are trapped inside the house with ghosts, murderers and other terrors..

The film is best known for a famous promotional gimmick used in the film's original theatrical release called "Emergo": William Castle placed an elaborate pulley system in some theaters showing the film which allowed a plastic skeleton to be flown over the audience at the appropriate time
Thanks to Castle's gimmickry, the film was a huge success.
