I love this recent interview Metro had with her. It makes me happy that Kristen is playing Bella Here's a snippet:
On self-inflicted pressure:
Unless there’s something about the story or that character I’m playing that literally needs to be fulfilled -- like, consummated -- unless it’s actually lived through and physically manifested, it’s just a story and it’s not done. So until you actually bring it to life, you basically have the capability of murdering the character on the page. If you don’t do it justice, then nobody else is ever going to see those things and you’re never going to learn from those experiences because you didn’t do it right.
So yeah, the thought of having to live through something that I find so worthwhile, and then subsequently have people learn from that through your own experience, I would do anything. I would jump off a cliff for it. Oh! There’s cliff-jumping in our movie. Perfect! (Laughs)
On being with the vampires or the werewolves:
Kristen shouldn’t open her mouth (Laughs). Kristen is entirely torn. Kristen should stop using her name in the third person.
On success and how Twilight has changed her:
I would do it for free every day [even] if nobody saw it. I cannot describe how good it feels to actually have something that is truly into your heart and soul actually affecting people. And that’s amazing. So that’s the biggest change. To put your heart and soul into something for years of your life and have it actually affect people is probably the most satisfying, and that is a completely ineffective word to describe how satisfying it is.
On Chris Weitz:
Besides all the technical, logistical reasons, Chris is so devoted and because he’s a man, there’s a common question. How is it having a man director? Is it a huge difference? You can’t make generalizations about people like that. He’s one of the most compassionate human beings I’ve ever met. Unfalteringly compassionate. He cares way too much for the story, and you need that. So he’s perfect.
