[4] During the next 11 serial chapters, Cody, now back on Earth, and his associates Joan (Aline Towne), Ted (William Bakewell) and Dick (Gayle Kellogg) battle an elusive lunar agent named Krog (Peter Brocco) and his gang of human henchmen led by Graber (Clayton Moore) and Daly (Bob Stevenson), who use lunarium-powered ray cannons to disrupt defense forces and weaken public morale.

After a second trip to the Moon, in which he captures a sample ray cannon for duplication in his lab, Cody tracks Retik's minions to their hideout where Krog is killed by one of his own devices, and Graber and Daly subsequently die in an over-the-cliff car chase.

For the camera's close-up flying sequences, Wallace was suspended in mid-air above a sound stage; he was lying on a horizontal board with the rocket suit's jacket closed around it, with a rear projection screen behind him.

[3] This serial is heavily padded with rocket-suit effects footage first filmed for the earlier King of the Rocket Men, to which some believe this was a pseudo-sequel.

[1] Republic's next new serial, Zombies of the Stratosphere, also used some of the previous Cody flying suit and spaceship film footage.

For unspecified reasons, at the last minute, Republic changed the character names of Cody, Joan, Ted, and Bob.

[1] In between these two serials, Republic had begun filming its first attempt at a TV series, "Commando Cody: Sky Marshal of the Universe", but stopped production after completing the first three episodes to begin work on "Zombies of the Stratosphere".

[1] Radar Men from the Moon was one of 26 Republic serials syndicated in 1966 as a 100-minute TV film under their "Century 66" package marketing name.

The first eight-and-a-half chapters of this Commando Cody serial were lampooned before the showing of their main feature-of-the-week (only half of the ninth installment was shown, with the in-show excuse being that "the film broke").
