One of the occupational hazards of being an actor, the reason why so many actors are insecure, is that the only way we know we're good is when other people tell us.

I know for a fact the reason I'm an actor is because one, two, maybe three people when I was younger saw something that I did, in youth theater or some small play somewhere, and said, "You're good."

Sunday at 11 o'clock is the most segregated hour in America. You have black churches; you have white churches; you have Hispanic churches. It's not really reflective of the world we live in, by and large, in America.

There's a nimble quality to the way a television actor can work. When that muscle gets strong it's a very valuable thing.

I know I had my equivalents in Adrian Lester and Lenny James when I was at drama school. I remember David Harewood doing 'Othello' at the National, and Adrian Lester having done Cheek by Jowl's famous 'As You Like It and Company' at the Donmar. Not necessarily performances I saw, but just the fact they happened was massively encouraging.

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

I truly believe slavery is why, as a by-product, we still have a disproportionate amount of black men incarcerated in America. It is an extension of that legacy, and that's not going to start to diminish until black people have a new sense of themselves that isn't tied to slavery and feeling inferior. I think the church can be instrumental in that, in terms of repentance, reconciliation and just being more embracing of each other - not just on Sunday, but in life generally.
