I'm very fortunate that I get asked to do very different kinds of roles and I realize how much I enjoy that. I enjoy the challenge of transformation. There are actors who play one character, or a certain kind of character, the whole of their lives. I really relish the opportunity to have the challenge to totally transform.

But I think the children of actors share a certain pragmatic approach. One is denied some of that 'running away with the circus' element of being an actor.

Jennifer [Lawrence] and Josh [Hutcherson] seem very, very grounded. They're getting down to the film like they did last time.

All of these red carpet events may seem natural for you journalists, but it doesn't feel natural for actors.

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

Often jobs are un-turndownable even before you read the script. You go, "Well, I have to do that."

I would absolutely like to play more leading roles. There’s no philosophy - well, the only philosophy, I suppose, is to try and do different things.
