Keira Knightley is The Duchess

Keira Knightley sports a massive coiffure as she rides in an ornate carriage (complete with footmen) on the set of her upcoming film The Duchess.

Keira, 22, plays the scandalous 18th century aristocrat Georgiana Cavendish, Duchess of Devonshire. The film is adapted from Amanda Foreman’s biography of the duchess.

Here, the crew has transformed the London Maritime Museum in Greenwich into an 18th century-looking street.

The Duchess is scheduled for release in 2008. The film also stars Ralph Fiennes as William Cavendish the 5th Duke of Devonshire and Dominic Cooper (Dakin in History Boys) as Charles Grey the 2nd Earl Grey.
