Kristen Stewart "hates" girl power films. The 22-year-old actress enjoys portraying physically and mentally strong characters and she was excited to play Snow White in her latest movie Snow White and the Huntsman because her alter-ego has "gusto and kicks ass."

"I hate girl power movies, when the people you're rooting for are not girls. That's what I was attracted to. I've always wanted to find a role where I can challenge myself physically, I really like getting the opportunity to hurt myself for the job but what I loved was that Snow White is someone who has the gusto and kicks ass but she's not a dude. She remains, steady. I'm not built to be physically strong, you have to outsmart someone, you have to be physically and mentally quicker, you have to have a strong heart."

Kristen was keen to play Snow White to "push" herself, and she particularly enjoyed playing the character when she overcame fears within the storyline: "Nothing is that simple. Every time Snow White has to do something and not be crippled by fear I'm into that, one of the things I wanted to do was see how far I could push myself. The reason they hire these big huge burly dudes to work on these movies is because it's hard."
