The droning background sound on the planet is from the music library cue "Caliban [sometimes spelled Calibal] and Ariel" by Desmond Leslie from "Vintage Sci-Fi" (JW 2073).

It has been theorized that the interior lunar base set's metal structural supports closely resemble the sets for the internal support structure of the observation nose of the submarine Seaview in Voyage to the Bottom of the Sea (1961). Since both films were released in the same year and knowing Irwin Allen's talent for recycling movie and television sets, it's possible that Allen's production unit at 20th Century-Fox was able to obtain and use these set pieces once production wrapped on this film.

Some of the spaceship sets as well as the helmets and air tanks on the space suits are the same props that were used in Men Into Space (1959).

This film utilizes stock music from renowned film composer Leith Stevens, specifically from Destination Moon (1950). In fact, it makes up quite an extensive part of the score. This would be repeated again in four years for Mutiny in Outer Space (1965).
