You have to have a certain single-mindedness if you want to reach the top of the profession, and I'm not sure if I've got that cold-eyed egomania that perhaps is needed to get to the top. So as long as I can keep paying the mortgage and keep myself interested, I'll be happy.
When my agent told me I had an audition for 'Friar Tuck,' I burst out laughing. It actually brought a bit of sunshine to my day. I was thinking: fat suit. I was thinking: shaving my head. It was so outlandish, such a crazy idea.
There are countless fantastic actors out there who are being denied the opportunity to play Broadway because they're not a name, and I think that's kind of wrong.
I've done so much different stuff, people kinda go, 'Do you live in Islington?' 'Did you used to go to so and so school?' And when I say I'm an actor, they don't believe me!
I remember when I first came to Los Angeles being staggered by the range of roles open to me. These were leading parts in shiny new projects, and what always excited me was knowing there was a possibility that I could actually get these parts. I always had the impression that I had a chance.
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.
I am the youngest of four children - three boys and one girl. I don't think becoming an actor had anything to do with seeking attention, though. My relationship with my siblings when I was growing up was close and playful.
British people are surprised that I'm British! It's extraordinary, I get tweets every day from British people saying, 'I had no idea you were British.'
When I was sent the script for 'Homeland,' I didn't think anything of it. Three months later, my manager rang and said: 'They are interested in you.' I read it and I realised, 'Yes, I do want this.' Then I got an email saying I'd got it.
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.
