1. KIRSTIE ALLEY AS SAAVIK IN STAR TREK II: THE WRATH OF KHAN
Years before she played a jock tease on Cheers or came out of Veronica’s Closet, this sitcom star played Lieutenant JG Saavik, a Vulcan Starfleet officer who bombs the no-win Kobayashi Maru training exercise in the first few minutes of Star Trek II: The Wrath of Khan. She spends the rest of the film trying to prove she’s smart and humorless (ironic, given Alley’s future career). Although Saavik returned in Star Trek III: The Search for Spock and Star Trek IV: The Voyage Home, Alley did not because she demanded too much money (she was replaced by Robin Curtis). Hey, as a Scientologist she gets to hang out with real aliens, right?
