Sometimes when we weep in the movies we weep for ourselves or for a life unlived. Or we even go to the movies because we want to resist the emotion that's there in front of us. I think there is always a catharsis that I look for and that makes the movie experience worthwhile.

What I was really overwhelmed with by Africa was its tremendous natural beauty; I got to go to some pretty amazing places. Every other weekend we got a day or two off and go on a safari or the natural wonders of Africa and if anyone gets the opportunity to go there, it's something you have to do in your lifetime.

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.

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

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 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.

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