Captain Video: Master of the Stratosphere is a 15-chapter serial released by Columbia Pictures in 1951. It was directed by Spencer Gordon Bennet and Wallace A. Grissel with a screenplay by Royal G. Cole, Sherman I. Lowe and Joseph F. Poland, based on a treatment by George H. Plympton. The serial is unique for several reasons--- in particular, it is the first and last film serial ever based on a television program, Captain Video and His Video Rangers.

Judd Holdren, in what was only his second starring screen role, plays Captain Video, the leader of a group of crime-fighters known as the Video Rangers. He faces an interplanetary menace, as the evil dictator of the planet Atoma, Vultura (Gene Roth) and his lackey, the traitorous earth scientist Dr. Tobor (George Eldredge) are planning to conquer the earth. 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).
