Lee J. Cobb was to star. After rehearsing, 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.

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 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.
