People always ask, 'Was it fun? Was it fun working on a movie?' I don't know if that's the operative word. It is challenging and interesting and all those other things, but fun isn't always.

It's very hard to impose your beliefs or a specific message about any given movie. I think that audiences always extract what they want from a film even if something isn't overtly political. They may or may not get it, and it's hard to control that.

Since I was very young I've been fascinated with nature and I actually wanted to be a marine biologist when I was very young. That was a great passion of mine. So I suppose in the off season when I'm not making movies, I became more and more active as an environmentalist trying to be more vocal about issues that I felt were important.

We actually did a lot of takes on this movie [J. Edgar Hoover]. I never left the set wanting more. That's for sure. I don't know. This was a very difficult character for me and a lot of the other actors here, and at times we went and did 8 or 9 or 10 takes on a single day.

Love at first sight? I absolutely believe in it! You've got to keep the faith. Who doesn't like the idea that you could see someone tomorrow and she could be the love of your life? It's very romantic.

I like to prepare as much as possible beforehand, but there's definitely that element of fear when you're on set, and you have to be conscious of it and use that fear to drive you to work harder.

Yes, I can play younger than my age. But I can play characters older than I am, too. I'm not an actor who can just play the kid.
