Giving kids the chance to see live theatre should not just be free, it should be compulsory.

I want to just be what kids believe in.

There was the 'Cosby Show' in America in the 1980s, which was a doctor in a beautiful Brownstone middle-class house. We just haven't created a role like that in the U.K.; it's always gangs and crime. We need to be brave.

To be on set with Tom Hiddlestone and Hugh Laurie is just fantastic. But during 'Homeland,' I was on set with Claire Danes and Damian Lewis, so I'm used to working with big hitters.

I'd like to live on horseback and just be a cowboy.

My black hero is and always will be Martin Luther King, not just because of the strength of his oratory but because his vision was very much the reality that I'd come to take for granted.
