Lee J. Cobb was to star. After production had already begun in May 1955, he had a heart attack and was not able to film. Producer Sam Katzman wanted to keep going, so director William Castle played Cobb's character in long-shots. After it was sure Cobb couldn't return, Gene Barry stepped in. In Castle's autobiography, he states footage of himself and Cobb, albeit unrecognizable, remains in the picture.
The filmmaker spent an inexplicably and inordinate amount of footage in the terminal of what is now William P. Hobby Airport, whose name was changed in 1967 to honor a Texas lieutenant governor. It was then Houston International Airport as of 1954, when the new passenger terminal opened. The art-deco interior may have appeared aesthetically pleasing enough to have factored into the editing. The terminal even had a nursery, something one would be hard pressed to find at many airports these days.

Frank drives a 1955 Lincoln Capri convertible. Only 1,487 were built. In excellent condition in 2021 an example of this car could be worth over $50,000.
