I'm pretty ruthless about that; I think when you sign over your story, you sign over your story.

I'm quite intuitive about what I pick. Often it's to do with what I've just done and how I'm feeling.

Although I'm not Christian, I was raised Christian. I'm an atheist, with a slight Buddhist leaning. I've got a very strong sense of morality.

I just don't see where I could possibly fit in directing a feature.

We grew up as kids watching those movies and we were exposed to themes of civil rights, unfairness, bigotry and fathers struggling against the kind of mob of the town, so you remember how you felt as a kid being taken seriously, that you are part of the human drama.

I found it an interesting portrait of a marriage in exploring notions of how one partner supports the other, whilst not jeopardizing the greater good - which is the family.

But just playing the partner of someone famous, I had a lot more freedom.
