It was a bit of a surprise that Jason of Star Command was actually spun off from Tarzan & the Super 7 for its 2nd season. Perhaps not as surprising were some cast changes.
James Doohan left the series after season 1 to work on "Star Trek: The Motion Picture". As a result, John Russell (ex-Lawman) became the new Commander. 70's movie legend Tamara Dobson ("Cleopatra Jones") joined the cast as well. Unfortunately, CBS didn't do Filmation any favors by burying Jason at the bottom of the lineup, where few affilates bothered to carry the show.
Let's take a look at the season 2 opener, "Mission to the Stars", in which Dragos (Sid Haig, ex-Mary Hartman, Mary Hartman) plots his revenge on Star Command.
No rating. Didn't see any of the season 2 episodes.
