67. Greta Gerwig
Occupation: Actress, writer
Biggest accomplishment this year: Starring in the critically beloved indie comedy Frances Ha
The 29-year-old Gerwig is a bona fide indie film darling. Her film Frances Ha, in which she portrays a failing dancer struggling with her friendships in New York, has opened to glowing reviews, particularly of Gerwig's performance. She even co-wrote the script, so the praise with which she's been lavished is entirely earned. While she waits for her next big opportunity in movies, she continues to lend her voice to Adult Swim's China, IL, where voices the character Pony.
