Captain Video: Master of the Stratosphere was the only serial adapted from television.
It was one of Katzman's first forays into science fiction and was soon followed by The Lost Planet.
As produced by Sam Katzman, the serial had a production budget much larger than the famously small budget of the DuMont Television Network's live daily teleseries.
The Captain Video chapterplay is a bit more satisfying to science-fiction fans, because it does make an effort to keep the action interplanetary, instead of earthbound. Captain Video and his teenaged sidekick, the otherwise nameless "Video Ranger" (Larry Stewart), must make frequent visits both to Atoma and to another distant planet, Theros. Both Atoma and Theros are filmed at Bronson Canyon, and Vasquez Rocks, so to distinguish the two, the Atoma footage is tinted pink and the Theros footage is tinted green in the original release prints. These colored scenes were processed by Cinecolor.
In the Captain Video teleseries, "Tobor" is the name of a large robot, who was one of the series' most popular characters. Calling a villain "Dr. Tobor" may have been intended to fool young theater-goers into thinking they would see the robot in the serial. In fact, the only robots on view are the odd fedora-wearing robots from the 1935 Gene Autry serial The Phantom Empire.
This was the second of only three science fiction serials released by Columbia. The third, The Lost Planet (1953), is a virtual sequel although with different character names, The slaves of The Lost Planet's evil extraterrestrial dictator Reckov (also Gene Roth) inexplicably all wear uniforms that look like those of the Video Rangers of 1951. In any case, the hero in The Lost Planet is a newspaper reporter named Rex Barrow, also played by Judd Holdren. As in the Captain Video serial, there is also an evil earth scientist, Dr. Grood (Michael Fox), in cahoots with Reckov of the Lost Planet.
Captain Video: Master of the Stratosphere was very successful when first released to theaters, and kept playing long after other serials had been retired to the vaults. It is one of only two serials that Columbia reissued three times (in 1958, 1960, and 1963).
Harmon and Glut describe this serial as a "rather shoddy, low budget space cliffhanger."
The serial includes several science fiction gadgets of the era. The Opticon Scillometer was used for looking through walls. Objects were made to disappear with the Isotropic Radiation Curtain. The Mu-ray Camera could photograph lingering images after the event. Temporary madness could be caused with the Psychosomatic Weapon. A variation on Radar was entitled the Radionic Directional Beam and the Radionic Guide and a Vibrator gun that worked like a Tazer.
