Guess Who's Coming to Dinner is a 1967 American comedy-drama film produced and directed by Stanley Kramer, and written by William Rose. It stars Spencer Tracy, Sidney Poitier, Katharine Hepburn and featuring Hepburn's niece Katharine Houghton. The film 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, and still was illegal in 17 states—mostly Southern states—until 12 June 1967, six months before the film was released, roughly two weeks after Tracy filmed his final scene (and two days after his death), when anti-miscegenation laws were struck down by the Supreme Court in Loving v. Virginia. The movie's Oscar-nominated score was composed by Frank DeVol.
