There are lines that just stick with me, like I mean I still can remember it's like every line that I say from Nightcrawler, I mean it's just always there.

I have a profound respect for cinematographers. That is my secret sauce. Like they are everything to me.

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."

Heath [Ledger] would walk up to a horse and could like silence the horse. Just literally he'd be like, 'Shh. Shh.' And then he'd get on the horse. I'd be like, 'I'm going to get on you.' They'd be like, 'F - off!' I didn't really have that style.

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.

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 can't not have something attached to like what actually happens in real life. Like I can't do a romantic comedy without there being something where like, in the case of Annie Hathaway's character, her character ends up having Parkinson's, you know? To me, I feel like that's love, you know? Like to me. So every movie has to have that kind of sense of that.
