A feature in Entertainment Weekly Magazine's July 22nd issue provides further insight about SWATH and Kristen Stewart's "Snow White" from Producer Joe Roth.
Roth says it will not be "the polite whistle-while-you work version of the fairy tale", "it's a girl empowerment movie".
EW further states that "Roth adds that Stewart won the role not just because she brings a massive fan base from the 'Twilight' films but also because of her tart, rebellious attitude and says that her Snow White will not be a naive victim."
Roth says that Stewart's Snow White will begin as a damsel but will turn into a warrior.
EB's recent profile on Stewart (Kristen's Choices) summed her up the same way. You can read it here.
