The lead character's name was changed to Larry Martin from Commando Cody for contractual reasons, so as to not conflict with Republic's using the character for an NBC science fiction series of the same name.
It was one of the first roles for Leonard Nimoy, who played Martian invader Narab.
The full serial version of the film was later edited to 93 minutes and colorized in 1995 for television broadcast and VHS.
The original series that this was edited from holds the record at 17 days for shortest filming period of any the Republic serials.
It is one of only 14 feature films to be re-edited and released from Republic's large catalog of serials.
