Guess Who's Coming to Dinner/Trivia

• Doing It for the Art: The film's studio backers were initially concerned that the terminally ill Tracy would be unable to make it through the shooting. Kramer and Hepburn put up some of their salaries to back up Tracy's insurance coverage.
• Real Life Relative: Katharine Houghton, who plays Joey, was Katharine Hepburn's real-life niece.
• Star-Derailing Role: This film was Poitier's final major star turn. After this film with him playing the ludicrously perfect and deferential African-American doctor, Poitier's critics slamming him as Hollywood's Token Minority really turned the screws and his acting career was downhill from there.
• Those Two Actors: This was the ninth and final screen pairing of Spencer Tracy and Katharine Hepburn.
