The World Entertainment News Network has named La Vie en Rose the sixth best film of the year, and has a nice bit about Marion's performance:
6. La Vie En Rose Marion Cotillard has already won the Best Actress Oscar for her portrayal of tragic torch singer Edith Piaf in this heartbreaking film. The French actress truly 'becomes' Piaf and even she admits she "channeled" the spirit of the legendary performer, who died too young, for the part. A true cinema masterpiece.
