What She's Done: The intense young performer played Joseph Gordon-Levitt's little sister in '(500) Days of Summer' and the controversial tiny assassin Hit Girl in 'Kick-Ass.' She also played the 300-year-old vampire Abby in the dark thriller 'Let Me In.'
What's Next: Moretz will be working with Martin Scorscese on the film 'Hugo Cabret' and was just cast as Emily Strange in a film adaptation of the comic about a Gothic teen.
Did You Know? Moretz's family is "very Christian" and she's not allowed to see R-rated movies, even the ones she's been in.
