Smell-O-Vision

Smell-O-Vision was a system that released odor during the projection of a film so that the viewer could "smell" what was happening in the movie. The technique was created by Hans Laube and made its only appearance in the 1960 film Scent of Mystery, produced by Mike Todd, Jr., son of film producer Mike Todd. The process injected 30 odors into a movie theater's seats when triggered by the film's soundtrack.

The use of scents in conjunction with film dates back to 1906, before the introduction of sound. In this first instance, a 1958 issue of Film Daily claims that Samuel Roxy Rothafel of the Family Theatre in Forest City, Pennsylvania, placed a wad of cotton wool that had been soaked in rose oil in front of an electric fan during a newsreel about the Rose Bowl Game. However, between 1903 and 1915, there were no games held, so it is unknown what the newsreel was about, although the Rose Parade (which has been held annually since 1890) seems likely.

In 1929, during the showing of The Broadway Melody, a New York City theater sprayed perfume from the ceiling. Arthur Mayer installed an in-theater smell system in Paramount's Rialto Theater on Broadway in 1933, which he used to deliver odors during a film. However, it would take over an hour to clear the scents from the theater, and some smells would linger for days afterward. Further attempts with releasing scents timed to key points in a film happened at a Detroit, Michigan theater with The Sea Hawk and Boom Town.
