Another option that should probably be on the list is Kim Cattrall's Lt. Valaris. I mean, it is Kim Cattrall.
Another interesting bit of Saavik trivia - the character of Valaris in Star Trek VI was supposed to be Saavik, but Roddenberry overruled the director since he didn't want to turn Saavik into a villain. Which I think really ****ing sucked - having Saavik in that role would have been perfect. She would have had a deep-seeded motive to never want peace with the Klingons (being half Romulan + David's death), and betrayal by a long-time crewmember would have been that much worse for Spock. Would have been awesome, especially if Allen would have reprised the role.
