Everyone always says, 'Kristen got 'Panic Room' because she looks like Jodie Foster.' But it was actually Nicole Kidman who was supposed to play my mother.

Reading something for the first time and getting this feeling like the material provokes you on some level, and doing the movie is really just sort of defining and figuring out why exactly you felt certain things when you read it.

I can only play characters that I feel like are real people and in a complete way and in such a whole way that if I fake any aspect of it I will have failed them and literally they're slaughtered.

I play music but only for myself. For my ears only.

Everyone's really different. I've worked with women who I've never wanted to tell anything about myself to, and I've worked with guys who have been pouring wells of emotion. So emotional availability is not a gender-specific thing.

The act is in itself a lie. You're faking something. The girl is lying there, she's pretending that she doesn't know the camera's on, she's getting banged, and "accidentally" it leaks out? Everyone leaks their own sex tapes! That's a ploy to get famous - that's not about the sex. It's not like when Madonna did her Sex book, and it was an artistic endeavor where she acknowledged it and spoke about it and was so upfront about it. It's different. It's not upfront. It's not honest. It's a ploy to get famous.

It's very rare that you get to play a character over the course of so many films. Bella meant a lot to me and she will always be such a formative event in my career. I grew up with her and she and I have been on this great journey together. I also see many parallels between her evolution and my own because I lived through so many things along the way while playing Bella and having this connection to so many people involved in making the films over the years. It would be impossible for me to separate my world from Bella's.
