I think, now, younger generations do take that for granted in a lot of ways. I don't think that takes away from the struggle of identity and what that is. But the struggle for identity is everybody's struggle. No matter what it is.

When I look at that now, all I think about is what a master [David Fincher] I was working with, and all of the things I could have watched and learned - and I didn't. And how, now, in my career, how I would love to have a ton of takes.

I think, when someone say, "When did you feel like an actor?" it's those moments when I feel like, "I'm an actor, wow." That's an extraordinary moment for me. So it's not like I walk around going, "I'm an actor."

I don't think I had any idea at the time how to work with someone as masterful as he is. And I don't think at the time I really understood what was happening. I think I was in a space where I was like: there are all these things. I was shooting all these takes with David [Fincher], and I was just confused, as a person, and as an actor feeling a little too big for my britches and that this thing was happening and then also not having enough skill yet, and technique to know exactly where I was, and know about the character.

I don't think I've made a mistake. I think I have behaved in ways that I am proud of; I think I've behaved in ways I'm not.

We are all from different cultures. Heath's [Ledger] Australian, really. I'm from here. Ang's [Lee] from China. But I think Ang gets very close in preproduction and rehearsals. And then he allows his actors - I don't think scared of actors, but I think he's scared of getting in on the scenes he's watching. The space he's watching. So he just totally disconnects from you while you're shooting.

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

Hardest emotion? They're all pretty damn hard; I don't know really if there's one specifically, but I do think, I don't know what's happening or what I'm feeling when I'm actually listening.

I think also what's interesting is that Maggie [Gyllenhaal] knows how much the choices that I make reflect what's going on in my life. Admittedly, probably, as my sister, and as someone who loves me - like, she can't wait to see become a father.
