I've become obsessed with learning other languages in movies, because I was like, since I was like, but I learned how to box so why don't I just learn another language for a movie?

My mum and dad are pretty amazing chefs and they spent most of my childhood cooking really extravagant things for my sister and me.

When I was young, before school, my father would wake me up and we would go running together. A love of being physical, being active and being outside was something he instilled in me.

As Uta Hagen would say, there's the representational actor and the presentational actor. My sister [Maggie Gyllenhaal] came up to me recently after she saw this movie, Southpaw, the movie I did, and she thought there was this exploration of that type of presentation, and a bit of representation as well, if I could be totally honest, where she was deeply moved.

I fooled around with Heath Ledger and Michelle Williams got pregnant.

I think I work as hard as I do now, because of a lot of lessons I've learned early on.

Ang Lee just allowed me to make what we would call mistakes and had no judgment of them. He also empowered me. You know, he's like, "You're my actor. I chose you. Whatever you do is right." Right? "I made the decision, I'm complicit in choosing you. And I went through everything I could to choose you, so I feel good and whatever you're going to do I'm going to give you this space." And so it was very empowering.
