To me this movie is about what is valuable. To one person it might be a stone; to someone else, a story in a magazine; to another, it is a child. The juxtaposition of one man obsessed with finding a valuable diamond with another man risking his life to find his son is the beating heart of this film.

There is a segment of the American population that has been excluded from the national myth, and that should be redressed.

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?

There is no reason why challenging themes and engaging stories have to be mutually exclusive - in fact, each can fuel the other. As a filmmaker, I want to entertain people first and foremost. If out of that comes a greater awareness and understanding of a time or a circumstance, then the hope is that change can happen.

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.

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

I have nothing against diamonds, or rubies or emeralds or sapphires. I do object when their acquisition is complicit in the debasement of children or the destruction of a country.
