You can shave your head, but I've had to gain a lot of weight for movies, I've had to drop weight really fast for movies. I've had to learn accents or embody physical behaviors or twitches and things like that. And sometimes you take to some things easily and sometimes [not]. That's the challenge of the job.

I love the idea of longevity in this career. But [producing] is not about, "Let me do this because this might happen 20 years down the line." Sleepwalking wasn't a vehicle for me, it was a film that pushed the ­envelope. I want to produce good stories, versus creating a niche where I can look after myself as an actor.

I've never been the kind of actress that just likes to show up and say my lines. I'm fascinated by what the crew does.

I don't like rehearsal.

I think more than anything, people just want to be understood.

I want my son to grow up with a mom that he could see and look at her life with all the mistakes and with all the failures and all the flaws and say, "My mom lived an authentic life. That was the life she wanted to live."

I've always said that I worry about being with a man who doesn't flirt.
