Notable Role: Alexandra King in The Descendants (2011)

The 21-year-old California girl undoubtedly had her breakout year in 2011, when she won the Indie Spirit Award for Best Supporting Actress for her role in the Oscar-nominated The Descendants, but she's not quite Jennifer Lawrence-famous. Well, yet. Like her contemporaries KStew and JLaw, Woodley is about to become a young adult franchise darling. Not only is she starring in the film adaptation of the teen trilogy Divergent, she's also bringing to life the character of Aimee Finicky in Tim Tharp's' YA novel The Spectacular Now and adopting the role of Mary Jane Watson in The Amazing Spider-Man 2
