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 wasn't really quite sure where Heath Ledger came from, and I think that's the feeling most people got when they were around him and why he was so extraordinary.

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

I think you hear a lot of people say 'I support the troops' and all of that, but I really feel deeply that I do.

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.

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.

It's funny to me that people find other people getting coffee really interesting, or walking their dog in the dog park.
