Hayward was only 12 when she landed her film debut — and breakout role — in Wes Anderson's "Moonrise Kingdom." Now 17, she has been a Mensa member for almost half of her life. She is also a published poet.

This year, she's appearing in "Manchester by the Sea," a drama starring Kyle Chandler, Casey Affleck, and Michelle Williams, and "Paterson," starring Adam Driver.
