By employing the intelligence of natural systems we can create industry, buildings, even regional plans that see nature and commerce not as mutually exclusive but mutually coexisting.

My happiest moment is the day they call wrap and I'm free. I'm not looking back.

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.

Where I grew up - we started out in Oklahoma and then moved to Missouri - it was considered hubris to talk about yourself. And the downside of that was that ideas rarely got exchanged, or true feelings.

When I first moved to L.A., I discovered Roy London. I didn't know anything about the arts, the profession; I had no technique, I knew nothing, I'm fresh from Missouri. I sat in on a few classes, and they just felt a little guru-ish and just didn't feel right to me. Until I met Roy.

Having children takes the focus off yourself, which I'm really grateful for. I'm so tired of thinking about myself. I'm sick of myself. You feel you want to be there and not miss out on anything. It's a true joy and a very profound love. You can write a book, you can make a movie, you can paint a painting, but having kids is the most extraordinary thing I've ever taken on.

I would love to work in a Bollywood film as there is so much drama and colour in the films there.
