Fresh from his latest stint as the evil Voldemort in Harry Potter and the Order of the Phoenix, Ralph Fiennes has signed on to play a cuckolded duke in the BBC period flick (redundant, I know) The Duchess, says Variety.
The Duchess is based on Amanda Foreman's biography of Georgiana, Duchess of Devonshire, a randy 18th century British aristocrat who became involved in a scandalous affair with Earl Grey (yeah, the tea guy). The part of Georgiana will be played by Keira Knightley, who, apparently, can't seem to get enough of those corsets.
