Cinematical has just received this exclusive clip from the period drama The Duchess (click image above or head after the jump to view), directed by Saul Dibb and based on Amanda Foreman's best-selling novel. Starring Keira Knightley as Georgiana, the Duchess of Devonshire, the film chronicles the life of a vibrant beauty and celebrity of her time; a woman held prisoner in an unhappy marriage, but one who'd risk it all for the love of a young politician. (Been there, done that -- right ladies?) Also starring Ralph Fiennes, Charlotte Rampling, Dominic Cooper and Hayley Atwell, the following clip takes us inside a pretty intense confrontation between Georgiana and the Duke of Devonshire (Fiennes) as they battle one another for the respect each feels they deserve.

The Duchess
(which is currently enjoying a limited release) expands to theaters across the country on October 10.
