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.

Eventually, if your career goes higher and higher, that's just how it is, but it's a little frightening. When I was younger and I thought about being an actor, I thought of the old Hollywood style of glamour, and that was so beautiful and appealing to me. Now, if you want to be an actor, it's not the same.

Chris was involved in that casting process. It was a different feel because New Moon was the first time that the Wolf Pack got together. With Eclipse, we were already established, so I didn't have that same bond or connection with David. It was very technical. He had a vision and an idea of what he wanted to do.

Even though she's dealing with a scar, Emily just carries on with life. It's not a big deal. While we were shooting the scene, I tried it different ways. I tried it where I was hiding my face, and Chris [Weitz] was like, "Let's try it where she doesn't care," and that's who she is. She doesn't care what anybody else thinks.

Stained is about a lonely bookshop keeper, and her past comes back to haunt her. I play a femme fatale, schizophrenic serial killer. They offered me the part and I was like, "I'm just curious why you thought I would be perfect for this role," and the director (Karen Lam) said, "You have this look that, when you're smiling, you're really sweet, but when you're not smiling, you look like you could kill somebody."

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.

Everyone was like, "You're life is going to change so much," but I don't think anybody recognizes me. Sometimes my friends will say, "Oh, that person recognized you," but I don't notice it. I don't even look at people when I walk because it weirds me out, if they're looking at me.
