My ambition is to keep the audience guessing... that is my path to a long career.

I think it's vital to have something outside your acting to keep you rooted in the real world, and help you fill the vacuum. If you have nothing else, it can be unhealthy. For me being a Christian has been invaluable: it simply means acting isn't the centre of my life.

I'm very aware that people find my wife and I's marriage disagreeable. But all I have to do is look at my four kids, and the love I have in my heart for my wife after 18 years of marriage, and the ugliness does fade.

I certainly don't feel there's a distinction to be made between a television and a film actor. I think there's a distinction between great actors and not so great actors. But I really think if you watch a person working in television give a wonderful performance, that person is f - ing great, because there is no time.

My parents are very hard working people who did everything they could for their children. I have two brothers and they worked dog hard to give us an education and provide us with the most comfortable life possible. My dad provided for his family daily. So, yes, that is definitely in my DNA.

I would make the tea on a Daniel Day-Lewis set just to observe how he crafts roles like he did in 'My Left Foot.' That was the equivalent of seeing Haley's Comet for me. I just couldn't understand how that was possible.

I love that as a black person I've experienced not being a minority. I think that's helped me to combat the minority mentality people can have here, which can stop them scaling the heights.
