 SPOILER: Valeris was originally written to be Saavik, Spocks  trainee from _Star Trek: The Wrath of Khan (1982)_ (qv),  _Star Trek III: The Search for Spock (1984)_ (qv), and  _Star Trek IV: The Voyage Home (1986)_ (qv) lending greater impact  to her characters betrayal. However, Gene Roddenberry (qv)  objected to the characters actions, ending up in a battle with  director/screenwriter Nicholas Meyer (qv) (who believed the Saavik  character was his to do with as he pleased). Roddenberry won the  dispute and the character was rewritten into Valeris, who is played  by Kim Cattrall (qv).
