It's hard for it to make a mark in this city because London has so much culture to offer.

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.

They seem much rarer now, those auteur films that come out of a director's imagination and are elliptical and hermetic. All those films that got me into independent cinema when I was watching it seem thin on the ground.

I do always feel very proud and flattered by being asked to be a part of American productions playing American characters.

We're blessed with, as we were on 'Harry Potter,' lead actors who are amazingly grounded people.

There are things that I would avoid, so I have the choice to say no, when I feel I'm repeating myself too much. But then there could be a reason to do that with a good director. So I think actors have to have a loose philosophy.

When you're training as an actor, a lot of the big work you're learning is to treat fictional characters like real people. You don't have the problem of discovering a backstory with real people, but there's always a mystery which is common to both fictional and factual characters. They are never quite the person you think they are.
