Director Saul Dibb takes the helm for this period drama adapted from Amanda Foreman's best-selling novel Georgiana, Duchess of Devonshire, documenting the romantic entanglements of Georgiana Cavendish (Keira Knightley), a beautiful and clever woman who becomes a celebrity of British high society when she marries the Duke of Devonshire (Ralph Fiennes) and becomes consort to one of the most powerful men in England. Beloved for her trend-setting fashion designs as well as her political activism, Georgiana's fire and wit make her a beloved figure everywhere but her own home, where her cold and distant husband's control over her is stifling, soon sending her into the arms of a another man -- an act that soon forces her to learn about the brutal difference in the rights afforded to 18th century men and women. - Jason Buchanan, All Movie Guide (Source)
