Keira Knightley on Colette: 'I think very often our voices aren't heard'

Keira Knightley has made a name for herself playing esteemed literary heroines, from Tolstoy's Anna Karenina to Austen's Elizabeth Bennet. In fact, the British actress has a flair for making period drama feel utterly contemporary and has racked up two Academy Award nominations along the way.
