Keira Knightley in The Duchess
Ah, this one looks fun as well. Unlike the more famous of History's blue-bloods, Keira gets to sink her teeth into a demanding role as Georgiana Cavendish, the Duchess of Devonshire.
A well-known beauty and social butterfly, the salon-cultivating Duchess led a scandalous life, documented fascinatingly in Amanda Foreman's rollicking biography, which is the basis to this film by Saul Dibb.
Literature students will be interested in the revelation that Richard Brinsley Sheridan's fabulous comic play, School For Scandal, was based on her life.
