Once I get on something, once I have something that I'm working on, then I become very obsessive. In a good way. I mean,... is there a positive way to say obsessive? It's a good thing and if you're out there and you're working on something right now and you're crazed and you're up in the middle of the night, or you can't stop thinking about it, or you have to keep reading other things about the subject that you're working on or whatever. That's good and I think that's necessary creatively.

Movies are details. Movies are billions of details that come into a certain moment. So with all the years and months and weeks and days and minutes of preparation, then finally you're shooting and it all comes down to these moments when you're shooting, which is sort of insane when you think about it. The details make a difference.

I think where I've instinctively found myself is that I am somewhat guarded in my public life. Being interviewed or being photographed or just in public attention, I have a certain reserve. But when I'm working I feel like I'm very open. At least I like to believe that I feel like nothing is held back when I'm in front of a camera. That's my job.

We all perform our lives in a way. And the actor is a perfect metaphor to get at that theme of "how do we find our authentic selves?" And that we all - whether we're actors or not - perform ourselves. As a way of searching. As a way of fumbling around and trying to say, is this my voice? Is this who I am?

I've always been pretty levelheaded. In show business you need to have a certain internal stability.

I can be very snobby about fiction, especially contemporary fiction. I can be kind of overly demanding, I think. But this is, I think, a good time. A lot of fiction comes out right now. So, I like reading the memoir. I love memoir, the biography, auto bio.

I'm just as intrigued by acting as ever. It's an ongoing process. There's no arrival. There's no point at which you say "Oh, OK, done it, got it." It just doesn't happen. And that's true of any creative endeavor. For me, it's just a lifelong interest. I'm very much interested in the craft. I started by doing plays and it took me a long time to feel comfortable doing movies, working with cameras. I felt like I was a theater actress pretending that I was a movie actress for quite a while. Now, I just love the process of working with cameras and being on a set and trying to put a film together.
