Every night I bring home flowers and burn candles. And I have a real sense that home is what starts everything inside of you.

I'm very sensitive. Emotionally, I bruise very easily. I'm a Leo, and this is very characteristic of our sign.

The people on my mum's side of the family are atheist intellectuals who are ueber-proper. My dad's side of the family are missionaries who are more comfortable sitting around in sweatpants than they are in a five-star restaurant. But those two influences converged in my life.

I got called and was told, "We'd like you to do The Hobbit", which was my favorite of all of them when I was a kid - "And we want you to play a character that's not in the books", I gulped and hesitated, but then I went, "These guys know this world, and they represent this world so well, that I actually think they've earned the right to have a little play."

I don't know if any of you feel this way, but it's like eventually, you see a woman come on screen and you go, "Oh, thank God!" You just sort of need a break from all this testosterone, which happened, I think, in one of my films, The Hurt Locker. I was in it for like five minutes, and people were like, "You were in that movie!" And I was like, "Well, kind of." And they were like, "No, you were!" 'Cause they needed a woman!

I eventually want to come back to Canada, to disappear, have nobody know me, and just be a writer and do what I want to do.

I just don't think that a lot of the time the messages we send kids prepare them for real life.
