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.
George Takei spent his early childhood in American internment camps for Japanese Americans, an experience he has spent decades documenting, including in the Broadway musical Allegiance.
Star Trek gave him Sulu, and The Undiscovered Country finally gave the character his own command.
He came out publicly in 2005 in response to a veto of same-sex marriage legislation and has been a prominent activist since, with one of the largest social media followings of any actor of his generation.
