Thank you Douglas Adams
Paramount was dissatisfied with the script, so its head of production Dawn Steele asked Nicholas Meyer, the writer and director of Star Trek II: The Wrath of Khan, to help rewrite it. Meyer and Bennett cut out Krikes and Meerson’s idea of having the Klingon Bird-of-Prey fly over the Super Bowl and the hint that Saavik remained on Vulcan because she was pregnant with Spock’s child.
Mark Lenard and Jane Wyatt play Ambassador Sarek and Amanda Grayson, respectively, Spock’s parents. Wyatt commented that although she generally disliked working with actors who were directing, she found Nimoy an exception because he could concentrate on being part of the cast as well as setting up the crew.
