But when you're writing a script - for me anyway - you have to sort of create an enforced innocence. You have to divest yourself of worrying about a lot of stuff like what movies are hot, what movies are not hot, what the budget of this movie might be.

Your'e seeing me develop, not only as a filmmaker if you've seen my earlier films, but you're seeing me kind of learn how to be a human, how my philosophy has evolved.

Of course for many years directors have had to go on the road with their movies and promote them and I've done that since the beginning. So that's not new but the forms of it are different such as with the internet.

It's impossible to make a movie out of 'Naked Lunch.' A literal translation just wouldn't work. It would cost $400 million to make and would be banned in every country of the world.

Casting is really a black art. It's a huge part of directing and it's the most invisible. It's one that people don't really think about or talk about. But you can really destroy your movie by casting it badly before you've shot a foot of film. And yet there are no guidebooks for it, there's no rule book to tell you how to do it. It's all your own experience and your own sensibility and your own intuition.

For example I don't work with William Hurt the same way that I will work with Viggo. They're different guys and they work in different ways. So a good sensitive director has his general style and technique and personality that he uses but you don't impose that on the actors.

At a certain point the audience shouldn't worry about catching every word and understanding every twist and turn, because at a certain point that's pretty much impossible.
