Idris Elba

When I look at my body of work, I've played a lot of characters who are morally conflicted - 'I'm right, no I'm wrong, I don't know what to do!' I want to play more characters who don't care as much, and who aren't as measured. They are what they are, no apologies.

I don't think of people as black or white. It's a question of are they photogenic or not? I don't think anyone says, 'Let's book her. She's black.' I think they say, 'Let's book her. She's good.' We've come that far.

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.
