Amy Adams, Jessica Chastain, Sarah Jessica Parker and Jennifer Garner were among the best-dressed Americans on the red carpet, along with Brit Thandie Newton and everyone's favorite Parisian, Marion Cotillard.
But the most show-stopping looks of the evening belonged to Anne Hathaway, who went sleek and chic in a short-sleeved black Burberry gown, and Dame Helen Mirren who went with pink -- pink hair, that is. The 67-year-old actress debuted a choppy new haircut dyed an icy pink, a perfect match to her white long-sleeve dress and dramatic silver coat.
