You know her as:
Feisty younger Stark daughter Arya
Why we like her:
As great as "Game of Thrones" is, the kids -- petulant Joffrey and whiny Sansa in particular -- didn't always come off that well. But Williams is fantastic as the tomboyish but vulnerable Arya and blessed us with one of the great TV lines of 2011: "Stick them with the pointy end."
Where else you've seen her:
"Game of Thrones" is the 14-year-old's first on-screen role.
