Ralph Fiennes has joined Keira Knightley in Saul Dibb’s The Duchess, which starts shooting Sept. 23 in London.
Based on Amanda Foreman’s biography of the scandalous 18th-century English aristocrat Georgiana, Duchess of Devonshire, the movie is being co-financed by Pathe and BBC Films. Hayley Atwell and Dominic Cooper have also been cast.
Knightley stars as Georgiana; Fiennes will play her husband, the Duke of Devonshire; with Cooper as her lover Earl Grey; and Atwell as her best friend, Lady Bess Foster.
