I knew everything about her backstory. I skimmed through all the books and read through everything that happened between Sam (Chaske Spencer), Emily and Leah (Julia Jones), so by the time we started filming, I knew everything that had to do with my storyline.

I've just always been that kid that was like, "Look at me! Look at me!," and doing performances and skits. I'm also, as most artists are, a very sensitive person, so I need that outlet to release that. Art needs to be in my life, otherwise I can't function as a human being. I heard Madonna say, "Live it, breathe it, eat it." That's how I am with the artistic part of myself.

It was a very, very intense film for me. I almost lost my mind because there are scenes where I have to kill people, and that energy is absolutely overwhelming. At the same time, as an actor, you never play a character with judgment. It's not my place to judge the fact that she kills people. It's for me to look at her psychology to see what makes her do that.

It was a realization for me when Oprah was talking about New Moon. I was like, "Oh, my god, she's watched a movie that I've been in!" People were like, "It just kicked in for you?," but it's just work for me. The idea that somebody that I've admired for so long had seen something that I'd done was when I understood the magnitude of it.

When you're actually feeling a character and you're going through the real emotions, and you're not fake acting, that energy stays with you and sometimes you can't get it off for days. It just resonates in your body, unless you have some sort of release, whatever it is.

I always say that you should just listen to it and see what you think it sounds like it is. I don't think it should be labeled. Most musicians feel like that. No one wants to put their music in a category. But, I don't think it's all over the place. I don't go from metal to jazz, or anything crazy.

I just read that one scene for Emily in New Moon, and it was pretty simple and straightforward. They liked that I did it really natural. They were like, "That was great!," even with what little I had. Sometimes just having those little scenes are a lot tougher than if you have five pages because you have to go from 0 to 100 in a snap.
