What was Smell-O-Vision?

Mike Todd, Jr., introduced the aromatic cinema gimmick Smell-O-Vision in 1960.

Smells were directed at each individual theater seat through a tubing system activated by a “smell track” on the film.

The only film made in Smell-O- Vision was Scent of Mystery.

John Waters’s “Odorama” system, introduced with Polyester in 1981, used a more low-tech method: scratch-and-sniff cards.
