I'm at the mercy of others because I'm not a director. I'm not a producer. I'm not a writer.

You're in a movie, so you have to think about how something plays. It's not like you're thinking about how an audience is going to react. You're trying to present the story. You're trying to illuminate the lives of these people in the story. So I'm thinking about how my behavior as this character best illuminates what's going on with them in this moment in time. I always say it's sort of the director's job. People think that the directors direct actors. No. Really, what the director's doing is directing the audience's eye through the film.

One of the things I admire so much about Atom Egoyan is that again and again he makes movies about the human condition, who we are, what we want, how we communicate to one another and this is also an exploration of a long-term relationship and what happens in it. There's human sexuality and all those kinds of things, so that helps - it all helps. You realise that I'm not a Playboy bunny.

I still battle with my deeply boring diet of, essentially, yogurt and breakfast cereal and granola bars. I hate dieting. I hate having to do it to be the 'right' size. I'm hungry all the time. I think I'm a slender person, but the industry apparently doesn't. All actresses are hungry all the time, I think.

At the Golden Globes, they put all the bigger stars in the front; the movie stars in the front, TV actors in the back. But even as a movie star, you can be outseated by a bigger star in any given year. It's kind of hilarious. You have to take it in stride.

But everything that I did starting out, every job that I had, I haven't regretted any of them. They've all been informative, interesting in one way or another. With a career, I think there's this idea that you're just trying to get somewhere. It's like, "Oh, okay, let's keep going, because if I do this, I can get this, I get this, this." It wasn't that way. I did what I wanted to do when it was in front of me, and I'm trying to continue to do that.

I always say about acting: the audience doesn't come to see you, they come to see themselves. So if you're able to give them an experience where they feel, 'Oh, my gosh, that's me, that's my story, they know!' then you've done your job.
