 The film rejuvenated the career of 1930s movie song-and-dance man and Disney Davy Crockett sidekick Buddy Ebsen, who had a small but effective role in this film as Doc Golightly, Holly's ex-husband.His success here led directly to his best-known role as Jed Clampett on "The Beverly Hillbillies".A diamond necklace at Tiffany's that Hepburn scorned as too flashy, was the Tiffany Yellow Diamond, which she wore in publicity photos for the film.
