Costumes worn by the ship's crew, including Prof. Konrad, and props, such as the blaster weapons and the belt radio with the retractable microphone, were re-used from Forbidden Planet (1956). Lisa Davis and Barbara Darrow wore costumes worn by Altaira, played by Anne Francis.
The film takes place in 1985.
The rocket shown on the launch pad with the designation TF-5 on the tail fin is a real V-2 being fueled at the White Sands Missile facility which flew on September 19, 1952. The footage was shot with with spherical lenses, and the first shot was horizontally stretched for the film's 2.35:1 aspect ratio, as the rocket wouldn't have fit in the frame if they simply - and correctly - had zoomed in the footage.
The basic plot element of this film, a planet inhabited solely by females, was used five years earlier in Abbott and Costello Go to Mars (1953).
