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?

I don't think movies can ever be too intense, but people have to understand why you're showing them the things you are showing them.

I look at modern life and I see people not taking responsibility for their lives. The temptation to blame, to find external causes to one's own issues is something that is particularly modern. I know that personally I find that sense of responsibility interesting.

It's always great to do a movie that you find is entertaining, but also can give some sort of political or social message.

Samurai culture did exist really, for hundreds of years and the notion of people trying to create some sort of a moral code, the idea that there existed certain behaviors that could be celebrated and that could be operative in a life.

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.

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.
