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."

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.

My little sister told me about the Twilight books and what a big fan she was. She said, "It's like Harry Potter in love," which it's not. So, when the audition came up, I wanted to get the film for her. It was great because I got to take her to the premiere. She got all dolled up and was treated like a princess for the day.

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.

There's so much going on, with child abuse, not having the right relationships and being in abusive relationships, that play into her, and that energy was constantly in my body for a month. I was the lead character and it was very, very intense.

I've done choir since I was tiny, and I've always tried to get into plays. They all just meshed together. Now with my career, especially with music, people are like, "Which one do you pick?" I don't pick either. They're just different expressions of who I am.

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.
