I think my strength is to do a take all the way through. I am definitely not someone who can do a sprint. Maybe I am not that smart, but it takes me a while to find the moment, and I like to be pushed toward it.

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.

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.

Being the youngest, I constantly have that insecurity of being the youngest, which ultimately is probably my drive. in a lot of ways. In terms of as an artist, the way we could communicate as a family very clearly was through movies and through acting, and when things became complicated with all of our own personalities, that's where we are most clear. I think that's also where we are most brutal with each other as well.

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 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.

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