The spaceship's communication device is a modified film editing machine (Movieola).
The astronauts' acceleration couches were common tube-lined poolside recliners.
The spaceship's navigation device is a Norden bomb sight, minus the stabilizer base.
On the bridge of the ship, a black timer device hangs on the wall. The device is a common darkroom timer, disguised with a piece of tape to cover the brand name.
Despite the overall low budget nature of this film, the producers obtained the services of the highly regarded cinematographer John Alton. This became one of two features shot by Alton during the final year of his active career. This did not indicate a decline in Alton's professional reputation; the other film shot that year was the far more upscale Elmer Gantry (1960).
