I walk around thinking job to job, trying to not have regrets.

Sometimes what I actually love to do is go to a farm and get fresh milk or watch a pig get slaughtered.

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.

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.

As an actor, no matter what, you're at the whim of so many other people all the time.

I think that I have done work where I feel like I've challenged myself, and then what's even more confusing is I've done work where I think I've challenged myself and no one's responded to it, and no one's interested in it.

Crazy people don't sit around wondering if they're nuts.
