A movie gimmick is an unusual idea intended to enhance the viewing experience of a film, and thus increase box office sales. Many of these have been used for just a few films, proving unpopular with either audiences or cinema owners. Smell-o-vision, which involved releasing relevant odors during the film, only appeared in the film Scent of Mystery as audiences did not enjoy the experience. Sensurround, a method for enhancing sound pioneered for the 1974 film Earthquake, was abandoned as it sometimes resulted in damage to movie theatres.[1] Other 'gimmicks' have gradually become more common in cinema, as technology has improved. Examples include 3-D film and the use of split screen, which was originally achieved through the use of dual projectors in cinemas.
