[6] Another 12-chapter "rocket man" movie serial, Zombies of the Stratosphere, was written as the direct sequel to Radar Men from the Moon.

[7] The name of the serial's main character was changed from Commando Cody to the more prosaic Larry Martin when the shooting schedule began.

This lead character renaming happened after the footage was shot for the first three episodes of Republic's proposed science fiction syndicated television series, Commando Cody: Sky Marshal of the Universe.

This is despite its having been released weekly to theaters and having a storyline that progresses through a dozen numbered and titled "chapters" until the villain is finally defeated in the 12th.

To add to the confusion, serial hero Larry Martin, who started out to be Commando Cody, wore the same costume again in Zombies of the Stratosphere.
