Star Trek III: The Search for Spock (1984)
Star Trek III: The Search for Spock is the Star Trek film that exists primarily to undo the consequences of the previous Star Trek film. Christopher Lloyd plays the Klingon commander Kruge.
Nichelle Nichols played Uhura and intended to leave after the first season, until Martin Luther King Jr told her personally that the role mattered because it showed a Black woman in a position of authority on television. She stayed.
Star Trek featured one of the first interracial kisses on American television, which several southern stations declined to broadcast.
She later worked directly with NASA on recruitment, and is credited with bringing in a generation of astronauts including Sally Ride and Guion Bluford.
