This 1950 Republic serial was made during the era of the Communist witch hunts in the United States. In the plot, a Martian plans with a former Nazi to bring the world under a "Supreme Leader." In a not too subtle casting decision, the Martian is played by Russian born actor Gregory Gaye.

The filming budget (expected cost) of this serial was $152,640 and the film-negative cost came in at $157,439 making it $745 over the budget (expected cost.) For some strange reason Revisionists have given Budget an entire different meaning than that used by the film-industry people and studios who actually made the films.
