Scent of Mystery is a 1960 mystery film, the first to use the Smell-O-Vision system to release odors at points in the film's plot. It was the first film in which aromas were integral to the story, providing important details to the audience. It was produced by Mike Todd, Jr., who, in conjunction with his father Mike Todd, had produced such spectacles as This Is Cinerama and Around the World in Eighty Days. Jack Cardiff called it the "one film I want to erase from my memory. The reason for this is that, through no fault of my own, the film was a complete disaster."
