I like Billy Beane for the fact that he - his idiosyncrasies, that he can't watch the games without getting too emotional, that he often has food down his shirt, that he tends to break a few chairs now and then. I mean, these things make him human.

You just have to get one misstep - that's an easy way to fall into caricature. Bad caricature.

I come from the belief that all good films find their time whether it's on opening week or sometime later. That's certainly true with some of my favourite films that might relate to this [The Assassination of Jesse James] film in terms of cadence like Pat Garrett & Billy the Kid, or McCabe & Mrs Miller or Days of Heaven. I found them 10 to 20 years after they were made.

So much of making movies is about discovery on the day, what you're figuring out. If you know everything going in, then it's not worth doing - it's already done. I'm interested in finding people who I think have a voice - and a very specific voice.

I look and there's our boy from Vietnam and our daughter from Ethiopia, and our girl was born in Namibia, and our son is from Cambodia, and they're brothers and sisters, man. They're brothers and sisters and it's a sight for elation.

A family is a risky venture, because the greater the love, the greater the loss... That's the trade-off. But I'll take it all.
