People say to me, well "What's the character you really want to play?" And I go, I don't know.

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.

I think that the idea of boundaries is being challenged everywhere. And I think our fascination with sci-fi is that it is a boundary-less world where we can kind of create the reality that we believe to be as opposed to the reality that is. It is about the beyond and the unknown in a different way than pretty much any type of storytelling is.

I think I'm generally - fear, fear is very still, so in terms of that kind of fear - there's so many different kinds of fear, but fear is something, particularly in movies, that's interesting, because it's created by the film maker, that was created by David Fincher, that's why he's brilliant.

Every journey starts with fear.

The best thing that I got was rehearsing with my father. It was always about the process of figuring things out, and trying something new, and having another take on something and keeping it alive.

I could draw ideas. I remember writing a paper for a seminar class. I remember writing a paper about - and this is going to sound really sort of pretentious, but that's where my mind was at the time - how acting and the performing artist can really be like a Bodhisattva, how they can communicate ultimately an idea in a way that can move and shift things. And that was wonderful. I didn't know many classes where I could try and relate the thing that I really loved and wanted to do into an intellectual idea, and that happened to be one of them.
