The story of racehorse Secretariat has been told many times, many ways. In 2010 Disney released their own star-studded telling of the horse's rise to glory with the help of his determined owner, Penny Chenery (played by Diane Lane). Everyone knows this film as a story about a horse's Triple Crown win. But really, it's as much a story about Chenery's struggle with challenging gender norms both personally and professionally. The horse Secretariat was her means to achieving success in a sexist industry.
