In the second of Republic Pictures' three "Rocket Man" serials, the government assigns Commando Cody (George Wallace) to look into a series of strange atomic explosions threatening the United States' defense systems. As Cody discovers, the threat comes from the Moon, whose ruler, Retik (Roy Barcroft), is planning an invasion of Mother Earth due to a severe lack of atmosphere on his own planet. Retik works through Krog (Peter Brocco), an inter-planetary henchman who does all the financing and hiring on Earth. Unfortunately, the hooded lunar visitor fails miserably on both fronts: the preparations for the invasion are severely under funded and the hired guns, such as former prison inmate Graber (Clayton Moore), less than competent. But despite these caveats, Commando Cody and his fellow space travelers, Joan Gilbert (Aline Towne) and Ted Richards (William Bakewell), have to suffer through 12 chapters before finally destroying the threat from the planet Moon. Radar Men From the Moon was filmed between October 17, 1951, and November 6, 1951, on a budget of $172,840. Most location filming, not excluding plenty of stock footage from earlier Republic serials, was done at the Iverson Ranch in Chatsworth, California. The serial was followed by a brief television series, Commando Cody: Sky Marshal, which retained Aline Towne as Joan Gilbert but replaced George Wallace and William Bakewell with Judd Holdren and William Schallert.
