This film was shown (at least in New York City) as a "Smell-o-Vision" movie. The theatre was equipped with a system that gave off various odors in sync with the film. The opening scene involved a butterfly flitting through a peach grove, with accompanying delicious odors. Later on, a barrel of wine fell off a cart going up a hill, and rolled down the street only to smash at the bottom, again to the accompanying odor. Correction - it's a rose garden, not a peach garden. The film played in several cities besides New York, including Los Angeles and Chicago.
The "Smell-O-Vision" gimmick did not work as intended. Moviegoers in the balcony said the aromas reached them too late to coincide with the onscreen action. Some said the scents were much too faint. Negative word-of-mouth and reviews doomed the movie and the gimmick.
Elizabeth Taylor, who makes a cameo appearance at the end of the film, was married to Michael Todd whose son Michael Todd Jr. produced the film. She was married Eddie Fisher at the time who sang two songs on the soundtrack: "The Scent of Mystery" and "The Chase"
The smell was not blown in through the air conditioning vents (As it was done in a previous film Behind the Great Wall.) - every seat had a little tube under it, and by the time the film played LA they'd perfected clearing the air between smells.
