HOUSE ON HAUNTED HILL: The theatrical trailer promoted the film as The House on Haunted Hill, although all advertising material and the title on the film itself were simply titled House on Haunted Hill. 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.Alfred Hitchcock  took notice of the low-budget film's performance at the box office, and set out to make his own low-budget horror film, which became the critically acclaimed hit Psycho (1960). Castle was himself a Hitchcock fan, and would try to imitate Hitchcock's work in later films. (from Wikipedia)
