Did you know

• Phyllis Coates accepted the role of Dale Marshall as a favor to director Jerry Warren, who was a former boyfriend; the actress originally cast in the lead could not do it and Warren could not find anyone else to do it in time. He convinced Coates to do it by telling her that the film would not be shown in California. However, after it was completed, she found out that Warren did indeed release the film in California, and she was told by at least one studio executive (at Columbia) that the film was so inferior and shoddy that the studio would not be hiring her again. On top of that, and as if to add insult to injury, Warren never paid her.

• The film remained unreleased for several years until it was released as the bottom half of a double feature with another film that was also directed by Jerry Warren, Teenage Zombies (1959).

• The opening shots of the film contain a copyright from 1957, but the film was never actually registered for an official copyright.
