1967: The drama "Guess Who's Coming to Dinner?" premieres in New York City. The movie, starring Spencer Tracy, Sidney Poitier and Katharine Hepburn, contains a then-rare positive representation of the controversial subject of interracial marriage, which historically had been illegal in most states of the United States. It would earn 10 Academy Award nominations, including Best Picture, Best Actor for Tracy and Best Director for Stanley Kramer, winning Best Actress for Hepburn and Best Original Screenplay. The film is also notable for being the ninth and final on-screen pairing of Tracy and Hepburn, with filming ending just 17 days before Tracy's death.
