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

I write from my stomach.

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.

Of course, I'm no dummy.

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

I'm completely aware of the fact that I'm a control freak.

I didn't have any desire I might have had 10 years ago to shoot every single word that I wrote.
