Star Trek III: The Search For Spock/Trivia

Directed by Cast Member: Leonard Nimoy, marking the first time a cast member directed a Star Trek production, paving the way for future cast members like Jonathan Frakes.
- Same can be said for Shatner, but people tend to ignore that one.
Hey, It's That Guy!: James B. Sikking as the Excelsior captain. Also, Phil Morris, who would play Jackie Chiles on Seinfeld, appears in the beginning as Cadet Foster.
- Not to mention Christopher Lloyd as "Doc" Kruge. His ship even looks like a DeLorean. And it was later used for Time Travel.
- And a post-Black Sheep Squadron pre-Night Court John Larroquette as the surviving Klingon crewmember.
- "Mr. Adventure" was played by Scott McGinnis, who became a prolific television director.
- I had to kill the Excelsior helmsman because he made a mistake. Now it's time to erase that mistake.
What Could Have Been: Edward James Olmos was Leonard Nimoy's preference for Kruge.
- Early scripts has the Klingons as a rogue group who commandiered a Romulan Bird of Prey.
  - And earlier than that, it was supposed to be Romulans period. It was only changed because Klingons were the better known bad guys of the franchise.
- In the novelization, Saavik and David Marcus became romantically involved (the seeds for this were planted in the previous movie's novelization); this storyline was completely dropped from the films.
- In the novelization, Saavik became pregnant with Spock's kid. This, too, was dropped.
