 Several changes were made in the movie to the relationship between  Katharine Hepburn (qv) and Howard Hughes (I) (qv). Hepburn did  not in fact leave Howard for Spencer Tracy . The two broke up long  before she had met Spencer Tracy. Hepburn and Hughes met at the set  of _Sylvia Scarlett (1936)_ . And lastly, Katharine Hepburns  brother committed suicide when she was little, not during her years  as a star.
