While we wait for the movie, the New Yorker has a nice piece on Amelia Earhart. Here's your teaser:
When [Amelia Earhart] lectured at colleges—as she did frequently, to promote careers for women, especially in aviation—she urged the coeds to focus on majors dominated by men, like engineering, and to postpone marriage until they had got a degree. On Earhart’s own wedding day, in 1931, the thirty-three-year-old bride handed her forty-three-year-old groom, George Palmer Putnam, a remarkable letter, which read:
You must know again my reluctance to marry, my feeling that I shatter thereby chances in work which means so much to me. . . . In our life together I shall not hold you to any medieval code of faithfulness to me, nor shall I consider myself bound to you similarly. . . . I may have to keep some place where I can go to be myself now and then, for I cannot guarantee to endure at all the confinements of even an attractive cage.
