Spencer Tracy and Katharine Hepburn (Academy Award winner for Best Actress) are unforgettable as perplexed parents in this landmark 1967 movie about an impending mixed race marriage. Joanna (Katharine Houghton), the beautiful daughter of a crusading publisher, Matthew (Tracy), and his patrician wife, Christina (Hepburn), returns home with her new fiancé, John (Sidney Poitier), a distinguished African American doctor. Christina accepts her daughter's decision to marry John, but Matthew is shocked by the interracial union, and the doctor's parents are equally dismayed. Both families must sit down face to face and examine each other's level of intolerance. In Guess Who's Coming to Dinner, Academy Award-winning screenwriter William Rose and director Stanley Kramer have created a masterful study of society's prejudices.
