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.

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

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.

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.

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.

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.
