Kirstie Alley as Saavik
Kirstie Alley may be one of the most popular actresses to appear in the series. She played Saavik in Star Trek II: The Wrath of Khan. The character was a Vulcan who lacked human emotions. Viewers liked her character for her beauty and strength, but she had to leave after contract negotiations fell through. In the end, she was replaced by Robin Curtis for the role. This part likely helped her get her role in Cheers.
