75. Carey Mulligan
Biggest accomplishment this year: Co-starring as Daisy Buchanan in The Great Gatsby
Carey Mulligan has become a bona fide star after her performance in as Daisy Buchanan in The Great Gatsby, and it seems inevitable that she'll be cast in many more films in the immediate future. She'll be in the Coen brothers' Inside Llewyn Davis, which just debuted to rave reviews at Cannes, winning the Grand Prix award as the second-best film at the festival. It will be released in mid-December. Mulligan also possesses one of the great marriage stories of all time, as she and husband Marcus Mumford (of Mumford & Sons) were childhood pen pals before reconnecting as famous adults after one of Mumford's concerts.
