To make a film, the final big collaborator that you have is the composer.

So with 'There Will Be Blood,' I didn't even really feel like I was adapting a book. I was just desperate to find stuff to write.

I've never been a fan of whimsical or confusing storytelling.

As I have got older and become a father, there's less and less time for films.

I don't think the competition's so rough, within the majority of movies made in Hollywood.

I don't get a sense of American pride. I just get a sense that everyone is here, battling the same thing - that around the world everybody's after the same thing, just some minor piece of happiness each day.

Well I'd really love to work with Robert De Niro, because he's still the most talented actor out there.
