I've often had the fortune to work on projects with a small theme I find very interesting enough to pursue and to be passionate about in the context of the story, then it may turn out there's a universality about my character which still resonates with many people as well.

Practically everybody I've ever worked with, I'd like to work with again. I had a great time with the people that I've worked with, and the directors, and a lot of the casts. There's really nobody where you'd say, "Oh, I got X, Y, and zed again! Gahhh, no!" It really brings a smile to my face, because in 95 percent of the cases, people I've worked with, I'd be thrilled to work with again.

Once you click into a character, to a certain degree, you can do a lot else. You can do other stuff, then come back and click right into the character. It's sort of funny that way, the way the mind works. Once it's there, it's sort of there. For the stage, for example, all through the day, you're not onstage. You're living your life, la-la-la, then the lights go down, then boom! All of a sudden, you're in this thing. There's a kind of reflex muscle trigger that happens, and all of a sudden you're back into the role. It's just getting there in the first place that's tricky.

David Mamet was great to work with. He was everything that I thought he would be as a director. He's incredibly articulate, an easy collaborator. Extraordinarily knowledgeable about film and writing.

I was already devouring literature and I was the ripe old age of 15 when I decided to be an actor. I just thought plays were the most fantastic way of expressing life. I thought I'd discovered Shakespeare - 'hey, there's a new guy in town, don't know if anyone's read him.' I was just excited about the whole thing, from day one.

I think Africa will have a crisper impact on Europe, as it has traditionally, and then that will filter into the American cultural psyche, in the way that India has.

Steve MCQueen created an entire family to tell one man's tale and I am delighted that so many of this family have also been recognised today. I am hugely grateful to the Academy for this great honour, and, of course, to Solomon Northup for sharing his story through his breathtaking book.
