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."

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.

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.

There was one female role, which was Emily. When I did the audition, I flubbed up. It was my first audition back from Christmas break, and I flubbed up and was devastated. In the audition room, they were like, "Oh, you did great!," but you never really know. So, I left the audition in tears.

I think the paparazzi are absolutely ridiculous. When we were filming, there was a lot of them. It's different being in L.A., where there are so many celebrities. But, when it was in Vancouver, it was all about the film, so there was paparazzi following us. It's just part of the business.

hat made me feel uncomfortable. People would be like, "Woah, that's crazy!," or they'd look at me really funny, but it also helped because that's how people look at Emily. I was like, "Come on, be sensitive! I have a scar on my face. It's not nice to just stare at somebody." That was really interesting.

Kristen is really focused and really quiet, as an actress. She just does her thing, but she's cool. I like her. I know a lot of people have mixed comments about her, but I think she's a rad person. She's just focused on what she's doing, as an actress, and she wants to pick the right roles, and she's committed to her craft. She's really cool. We got along. There weren't any tensions or anything.
