Radar Men from the Moon is a 1952 Republic Pictures' 12-chapter movie serial, the first Commando Cody serial starring newcomer George Wallace as Cody, Aline Towne as his sidekick Joan Gilbert, and serial veteran Roy Barcroft as the evil Retik, the Ruler of the Moon. The director was Fred C. Brannon, with a screenplay by Ronald Davidson, and special effects by the Lydecker brothers. This serial recycles the flying sequences from Republic's earlier 1949 serial King of the Rocket Men. It was later released by Republic in 1966 as the 100-minute television film Retik the Moon Menace.
The odd naming choice of the serial's main hero, "Commando Cody," was possibly an attempt by Republic to make young audiences think they were seeing another adventure of Commander Corry, the hero of the popular ABC TV and radio series Space Patrol (1950-1955). There is, however, no surviving evidence that this was a consideration by anyone at Republic.
The plot for Radar Men from the Moon is as follows:
Commando Cody (George Wallace) is a civilian researcher and inventor with a number of employees. He uses a streamlined helmet and a sonic-powered rocket backpack attached to a leather flying jacket. Cody also uses a rocket ship capable of reaching the Moon. When the U. S. finds itself under attack from a mysterious force that can wipe out entire military bases and industrial complexes, Cody surmises (correctly) that the Earth is coming under attack from our own Moon. He then flies his rocket ship there and confronts the Moon's dictator, Retik (Roy Barcroft), who boldly announces his plans to both conquer Earth and then move the Moon's entire population here using spaceships.
On Earth, Cody battles an elusive lunar warrior named Krog (Peter Brocco) and his gang of human henchmen, hired to steal and stockpile various supplies for the coming invasion. (Source: wikipedia.org)
