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

There is something universal in the theme of a man trying to save his family in the midst of the most terrible circumstances. It is not limited to Sierra Leone. This story could apply to any number of places where ordinary people have been caught up in political events beyond their control.

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.

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.

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 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.
