I have never been much of a Keira Knightley fan myself but in this historical drama she performs admirably. This is the sort of movie that would ultimately rise or fall based on the execution of her role. Knightely, who I usually find rather aloof, is adept at capturing both the charm, grace, warmth and intelligence. that made the real Georgiana Spencer so captivating to so many. Ralph Fiennes, an actor who disappears into roles like ice in a teacup, makes the Duke a complex and almost sympathetic figure, heightening the sense of tragedy for these birds in gilded cages.
