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.
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.
In an interview, director Edward Bernds said that Zsa Zsa Gabor got very "testy" with the actresses playing the Venusian girls. They were mostly beauty contest winners, and were many years - and in some cases a few decades - younger than her. When she noticed that the crew was paying more attention to the tall, leggy, mini-skirted "Venusians" than they were to her, she became very difficult to work with. He said that Gabor gave producer Ben Schwalb such a hard time on the picture that Schwalb eventually wound up in the hospital with ulcers.
