I do think opportunity breeds bravery. It's such a competitive profession, no one owes you anything, talent in itself is not enough. I went to drama school with so many great actors who are not doing it anymore and it's circumstantial.
Getting to do what I think was my fifth BBC drama with Nikki Amuka-Bird - we've done 'Shoot The Messenger,' 'Five Days,' 'The No. 1 Ladies' Detective Agency,' 'Born Equal' and now 'Small Island' - was another highlight for me. And filming in Jamaica was great, too.
One of the things the BBC does better than anyone is period drama.
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.
