“Poetry is the key to the hieroglyphics of nature.”

“As an actor, whether I'm playing Othello on stage or David Estes on 'Homeland,' that ability to give into your imagination is something that I enjoy.”

“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.”

“I grew up in Birmingham, but my parents are originally from Barbados. My dad, Romeo, was a long-distance lorry driver, and my mother, Mayleen, worked in catering.”

“My parents are very proud of my success but still worry, as I'm in a profession where there is no guarantee of work. They have always supported my decision to go into acting, but there have been tough times work-wise.”

“On the red carpet, one tip is to suck in your cheekbones - apparently it looks better on camera. I don't know, though; I think a nice smile is best.”

“As an ambassador for the aid agency Cafod and the Anthony Nolan Trust, I need to be sure that my public support for those charities is a help for their work, not a hindrance.”

“Back in 2005, the Anthony Nolan Trust could have asked me just to speak out about the lack of ethnic minority donors on the bone marrow register, but that would have meant nothing if I wasn't prepared to join up myself.”

“I try to ensure my daughters are not spoilt. They are very aware of how lucky they are and appreciate it. We have had some lean years, so they know it's not all about luxury, travel, and hotels. They are grounded, and I'm grateful for that.”

“Thought is the wind and knowledge the sail.”

“I remember coming back to the U.K. after spending five months in Charlotte for 'Homeland,' and I just found myself just wandering around London. There's nothing like it - the buildings, the architecture, the sense of history, the sense of culture - there really is nothing like it.”
