I basically enjoy doing films that are about something, that have complex roles that I can sink my teeth into. Basically, I gravitate to things that scare me. They might be things that I don't think I know how to play. I like trying to find within me where this character may exist. Whether is it is a fictional character or not I am not motivated by that. It is more about how challenging it is. It is just so happens that the more high profile things I have done have been historical characters.

At the end of the day, everyone knows what it is to be loved and to aspire to love someone, to want to be loved, the loss of love, or having their love be opposed, whether it is family, friends or politically.

I was sometimes called 'coconut' when I was at school.

When you reflect upon the significance of Dr. King to this nation, it's criminal that he hasn't had a feature film that was centered around him until now. That, in and of itself, was emotional. But when you're doing scenes on the Edmund Pettus Bridge, with people still living in Selma and now in their 60s and 70s who had actually marched, who were there that original Bloody Sunday, that's humbling... that's deeply moving. You're no longer acting at that stage, you're just reacting, because it takes the filmmaking process to another dimension.

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.

For me, I'm always looking for opportunities to work with people who are better than me, who are more experienced than me, people from whom I can learn. And who could I learn more from than someone with an unprecedented movie star career that has spanned over thirty years whose name is Tom Cruise?

I like to think of myself as a physical actor.
