But I'd be lying if I didn't say that every time you go to make a film, you're desperate to either do it better than you did it last time or to not repeat yourself.

Clinton used to like to get out of the White House a lot. He would take night trips to McDonald's, and stuff like that. I think he wanted to get out of the house.

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

Acting is the hardest job in the entire world. By far. Harder than ditch digging.

I remember being taught in school that you would underline things that you liked. I remember just underlining everything as a kid, thinking, 'This has all gotta be important!' I would just underline the whole thing!

No matter how many times you do it, you don't get used to the sadness - for me at least - of coming to the end of a film.

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.
