Jennifer [Lawrence] is amazingly grounded in the midst of all this to do. It must be unnerving and hard to relate to the amount of attention she generates.

I work best when a little scared, when there's so much more than the lines to think about.

There's not a huge pile of scripts at home. It's what happens to be on the table at that moment with your availability. And then you have no control over when these things come out.

Best ever was filming in Barcelona last year, and I had a couple of scenes with De Niro. He's a very shy man. Speaks so quietly that people tend to bend down and adopt the same tone, almost the same voice, whenever they talk to him - watching, you'd think someone's offering to carry out a hit for him when they're just offering him a cup of coffee.

I know, for a fact, that I'm a very different person on my own than I am with someone else. We are different with each other. These things are constantly adjusted. And that's true of humans. That's not just true of famous people.

Certainly for my father, there were great times, good times, not-so-good times. He might be shooting a Fellini film for six months, then not working for two months. I'm used to that dynamic.

You come in as this satellite part of the film [Catching Fire], so I only see Stanley [Tucci] in my scenes. These kinds of movies have so many different components; it's about as different from doing The Girl as you could imagine.
