I was in the car driving back, after having done a scene where I kill somebody, and I just said to the driver, "I can't talk right now. I'm too emotional." The whole car ride back, I was just crying.

Most of the time, it just sat there in my body, until the weekend. After five or six takes of crying, your body does not want to cry anybody. Your body is like, "I'm over this, can we start laughing, or something?," but you have to keep the emotion. It's a really weird process and it definitely just stays with you.

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.

Because I have the scar, people are like, "Who did you play in the film?," and I tell them, "The girl with the scar," and then they're like, "Oh, yeah!" I think most people expect me to have the scar.

Yes, there was a massive difference between their styles. David is a very technical director and Chris is an actor's director, in the sense of emotion. With David, he's done horror films, so Eclipse is much darker, whereas I found New Moon really light and poetic. I didn't have as much interaction with David because the casting process was already done.

I'm a goofball, so I think comedy is one of my stronger points, as an actor. I just never get to do it. But, I'm taking classes at Groundlings, where Will Ferrell and Lisa Kudrow studied, and it's all improv comedy. It feels good to be able to do that and be funny.

After the make-up process, I was like, "I never want to do a sci-fi movie where I'm in make-up for seven months." It's interesting. It was my first time ever getting prosthetics. They put this goopy stuff all over your head and they tell you it's like a facial, but it's actually very claustrophobic. All they have are these places where your nostrils are and I kept thinking that they were closing up, but they were like, "No, we're looking at it." So, they made a mold of my face.
