The Duchess

Yes, Keira Knightley is capable of taking on parts that don't require elaborate period costumes, but what fun would that be? Georgiana Cavendish, Duchess of Devonshire is the Diana of her day – fashion-setting, fearless in the face of royal tradition, adored by the people and trapped in a loveless marriage. Let the romantic quadrangle ensue! Georgiana bears it as her husband takes up with her best friend, finding comfort in the arms of the dashing Earl Grey (please, no teabag jokes). Passion, anger, violence, illegitimate children, the Whig party – it's all in there, serving as plot fodder for what is at its best a sumptuous feast for the eyes.
