I can tell you that my contribution based on my interpretation of the book is unchanged. The other things, in terms of doing the research and following the trail of it, were probably pretty similar to what I would have done then. I think that what makes me celebrate that it took the 10 years is the various other people and contributors that I ended up having on board.

The heartbreak that it might not happen wasn't something that I wanted to face with any more weight. Then, when I got the call to go ahead I never thought for a second as I was approaching it who I would get - that would come later. Again, I think the idea was that I now had the rights to make the movie and I can start writing it but if I have to wait another 10 years before I find an actor that's right for it, I'd be very happy to do that.

There's the old notion that where there's choice, there's chaos, and where there's no choice, there's clarity. If you've got no choice, you've gotta be there, and you've gotta have your heart in it. It leads to a much less self-conscious life.

Sacrificing American soldiers or innocent civilians in an unprecedented preemptive attack on a separate sovereign nation may well prove itself a most temporary medicine.

On any movie I'm involved with, I say what I think.

The advice you give to young directors for sure is to go out and become some version of a successful movie actor. Do that first and say yes to people like Terrence Malick and Clint Eastwood and Woody Allen when they come and offer you movies. It's a great front row seat to filmmaking.

I don't have any particular excitement about working with any specific director or actor at this point.
