Which actress played Fantine in 'Les Misérables' (2012)?

Anne Hathaway played Fantine in 'Les Misérables' (2012), a role for which she won the Oscar for Best Supporting Actress. To prepare, Hathaway lost 25 pounds and got a real haircut on camera. Her performance of 'I Dreamed a Dream' was filmed in a single take, with Hathaway singing live rather than lip-syncing, as is customary in film musicals.
