Long before the concept existed, the Duchess of Devonshire, Georgiana Spencer (Keira Knightley), was the original "It Girl" -- ravishing, glamorous and adored by an entire country. Determined to be a player in the wider affairs of the world, she helped usher in sweeping changes to England as a leader of the forward-thinking Whig Party. But even as her power and popularity grew, she was haunted by the fact that the only man in England she seemingly could not seduce was her very own husband, the Duke (Ralph Fiennes). Directed by Saul Dibb (Bullet Boy, The Line of Beauty), The Duchess is the story of an extraordinary woman who rose to fame by staying true to her passions in a world of protocol, gossip and social rules - and paid the price. Based on the award-winning biography Georgiana, Duchess of Devonshire by Amanda Foreman.
