The script for the film was unusual. It was typed sideways on legal-sized paper, with each side of the page corresponding to what happens on each side of the split-screen. Writer Richard L. Bare had trouble finding a typewriter with a wide enough carriage to accommodate the longer paper.
Initially MGM planned to release the movie as two separate films, to be shown by two interlocked projectors on a wide theater screen. At the last minute, they decided that a single piece of film would give them a larger market, so they squeezed both images onto 35mm.
Film uses a gimmick entitled "Duo-Vision", basically a split-screen effect that lasts the whole film.
After catching David Bailey in a popular commercial for Mitchum deodorant (in which a half-naked Bailey lies in bed and proclaims "I didn't use my deodorant yesterday, and I may not today") writer/director Richard L. Bare asked the actor to come to California for an interview and offered him a role in the film almost immediately.
Tiffany Bolling has admitted that the main reason she took the part in the film is because it presented her the opportunity to sing.
