Ross Elliott is listed in the show's credits, but does not appear in the program. He was originally cast as Jor-El but for unknown reasons was replaced by Robert Rockwell, who did not receive credit for this substantial role.
This was the first television series to be based on a DC comic book.
The logo of the U.S. Gauge Company is on the dial of the pressure gauge on Jor-El's control panel.
It is now common knowledge that Clark Kent's Earth parents were named Jonathan and Martha, but Kent's parents here were named Eben and Sarah. This is because the comics themselves were inconsistent with the Kents' given names until the characters became major players in "Superboy" comics stories at about this same time. The names Sarah and Eben were first used in the novel "The Adventures of Superman" (1942) and in the first Superman serial.
Sarah and Eben Kent found Clark on April 10, 1926.
