I went to meet Joe Johnston, the director, and he's charming. I've been very lucky. Most of the directors I've worked with are charming. But Joe's a particularly charming man, and he showed me lots of designs and, rather memorably, welcomed me to the Marvel Universe.

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

When working abroad you work pretty hard, but with time off, this is the greatest job in the world. You drive. You explore Memphis, or wherever you've landed, or go and see Dr John, or the Californian landscape. And, yes, I've had a few good meals.

I didn't sound anything like Capote at the screen test. It was more like Bob Dylan. In his early years. With the flu.

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

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.

You're playing a character in a drama who happens to be based on someone who existed. It's never going to 'be' that person, but it's based on someone well-known, and you want to create enough of that person for it not to be a distraction.
