It's always hard when you're playing someone for a lot of people out there who are going to see the movie after reading the books. There's a communion between a reader and the writer, so people will have an idea who Sirius Black is and I might not be everyone's idea of that.

When people said Africa would change me, I didn't understand what they meant. To see the poverty in the townships, for instance, is overwhelming. I found it heart-wrenching to see young children walking barefoot and hungry in the dirt. I'm the kind of person who wants to change the world right here and now, so I got frustrated.
