I think 'The Wire' really is relatable. It reflects an ongoing issue across America, about inaccuracies in major cities between rich and the poor and some of the things that go on behind the red tape of council and government bodies.

It was deeply important for me to understand where Mandela came from. Because we know where he was going, and that's a famous story, but who was he? Where did he come from? What was his upbringing?

Being able to work with Ridley Scott on this film is like being able to play on the Olympic team for actors.

The less I talk about being black, the better.

There are things that I really find important, and that we need to remind ourselves of. When you think about disability, do you really think about it? Someone who's a full-time trainer or a boxer, someone who's got a major disability, but who doesn't let that get in his way, that's a really good message for someone who is able-bodied. It can make them think, 'Wow, I suppose I could be doing better for myself.'

I lived in America for a long time before I started working as an actor. Some actors show up on set and have never done an American accent before, so they rely on a slew of technical mechanisms. Part of what makes an accent is understanding why people speak that way - you have to understand the culture.

I'm tactile, very tactile. A woman who has really nice, looked-after skin is such a turn-on for me. It's always sexy.
