Big break: Playing Jennifer Jason Leigh's daughter in the 1996 film Bastard Out of Carolina.
Also seen in: Stepmom, Donnie Darko, Saved!, and Into the Wild.
Prized style possession: "Burberry combat boots with 6-inch heels. I bring them to every location shoot. I never end up wearing them, but I just have to have them with me. Heels instantly put me into a new head space."
On growing up in Hollywood: "You get a false sense of inner beauty. Every teen has to deal with 'Am I beautiful? What is beauty? Is it given to you by your parents? By a boyfriend? Is it self-generated?' As an actress, you tend to interpret beauty by other people's understanding of you. But I've realized that beauty is yours to behold. Other people get to cherish it, but you have to create it for yourself."
Spot her next in: The miniseries Hatfields & McCoys with Kevin Costner and Bill Paxton, premiering on History, May 28.
