Zombies of the Stratosphere (Republic Studios, 1952) was intended as the second serial featuring "new hero" Commando Cody and the third 12-chapter serial featuring the rocket-powered flying suit introduced in King of the Rocket Men (1949). Instead, the hero is "Larry Martin", preventing Martian invaders from using a hydrogen bomb to blow Earth away from the Sun so that Mars can take its orbital place. The director was Fred C. Brannon, with screenplay by Ronald Davidson and special effects by the Lydecker brothers. The serial is remembered today mainly because Leonard Nimoy plays one of the three Martian invaders, Narab. In 1958 a feature film called Satan's Satellites was made by re-editing footage from this serial.
