Solid followup to RADAR MEN, this fast-paced Republic serial pits federal agent Larry Martin against Martians hell-bent n blowing the Earth out of the solar system and into oblivion. Larry often dons the rocket suit to fight them, so we get lots of shots of him flying, and these scenes are quite realistic. The special effects team rigged a dummy on a wire and flew the thing several feet above the ground. The only catch is, Larry's not exactly a superhero and manages to get beat up and knocked out several times by his much tougher opponents. Also, he's a lousy shot with a handgun. So's everyone else, for that matter. No one ever gets shot. Also, everyone -- good guys and bad guys -- wear the same suits and fedoras, and they're all thin as rails, so at times it is hard to tell who's who. When they fight, they almost never lose their hats, the better to hide the stuntmen. Only the Martians are dressed differently. They wear what appear to be costumes from some old King Arthur movie. And they're green, of course. The amazing physical stunt work was handled by three of Hollywood's best stuntmen. It's wise not to watch this all in one sitting, by the way. Too much repetition of the flying scenes. There is a condensed, non-serial version from 1958, if you prefer. Regardless of what you're heard about colorization, make sure to watch this in computerized color. And watch for a young Leonard Nimoy as Martian No. 2.
