(Cover) - EN Showbiz - Kristen Stewart "doesn't play by anyone's rules," according to her Snow White and the Huntsman director Rupert Sanders.

The Twilight actress stars in the fairytale film and although Kristen's beauty is undoubted, Rupert says she has a lot more going for her than just that.

He told VH1 that there were many qualities about Kristen that he really appreciated.

"She's very vital," Rupert gushed. "She's very on the edge and very rebellious, which I like."

"She doesn't play by anyone's rules. She's just got all those things that make a very modern and intoxicating Snow White.

"When I first met her with the producers, we all saw something really raw and primal in this girl, and we really liked that." (C) Cover Media
