And how deeply do I let business considerations affect [screenwriting] choices that might otherwise be more or less esthetic? . . . Do I choose the upbeat rather than the downer ending because I know it will score better at the preview? Can the idea be sold in a single sentence? Can it compete with space aliens and tornadoes and missions impossible?

However much I may like to talk about or be interested in a more philosophical or moral agenda, [film] is, ultimately, about narrative. And it's about telling stories that are engaging and dramatic.

I think one of the privileges of being a filmmaker is the opportunity to remain a kind of perpetual student.

I maintain that no movie can be funny enough. I mean even the most serious, even the most intense movie and I know enough about life to know in those dark moments inevitably someone will say something funny and I will be part of the whole experience.

I am a fan of movies and there is something about watching film that is burned into celluloid for all time that is now a piece of history. You go watch, being a fan of classic films and my children and their children are going to be watching these movies.

It seems that almost every time a valuable natural resource is discovered in the world-whether it be diamonds, rubber, gold, oil, whatever-often what results is a tragedy for the country in which they are found. Making matters worse, the resulting riches from these resources rarely benefit the people of the country from which they come.

You do these movies, you give it out to the world and you really have no idea how people are going to react to you.
