Jonathan Harris was supposed to play Commander Gampu on Jason of Star Command, as this was to be a spin-off of his series Space Academy. In a personal interview, Harris related that while the stories about his demand for higher pay is not wrong, it is also not right. According to Harris, Filmation planned to film the series like an old movie serial, with each show running about 15 minutes. Space Academy was a half hour show, and Harris was asked to recreate his role of Gampu for half the money he was paid on Academy. He felt just because they cut the running time in half, they could get him for half the money. So, when Lou Scheimer said he would have no problem getting Harris because they were friends, it meant that he thought he could con Harris into taking less money and save on his production costs. Harris refused to take the paid cut and Jimmy Doohan was brought in as a replacement character.

Originally a segment of Tarzan and the Super 7 (1978); costumes, props, and sets were recycled from Filmation's CBS series "Space Academy," from which this was intended as a spin-off.

James Doohan was unable to return for the 2nd and final season due to his commitment on "Star Trek: The Motion Picture".
