Julie Andrews was the original Eliza in the stage musical. Audrey Hepburn was cast as the movie Eliza because studio head Jack Warner wanted "a star with a great deal of name recognition". Julie Andrews did not have any movie experience. He thought a movie with her would not be as successful as a movie with Hepburn. Andrews went on to star in Disney's "Mary Poppins" that same year. She won the Best Actress Academy Award over Hepburn.
