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.

I think it's too easy often to find a villain out of the headlines and to then repeat that villainy again and again and again. You know, traditionally, America has always looked to scapegoat someone as the boogie man.

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.

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.

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.

There is no reason why challenging themes and engaging stories have to be mutually exclusive - in fact, each can fuel the other.

To make a great movie is such a combination of different things that need to come into play to actually make a memorable film and not have a film to fall by the wayside, to have something live on during the years, and one of those elements is the commitment the actors have to their performance.
