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.

You don't just win an Oscar because you're a great actor. You campaign for that Oscar: you engage with it; you go on the David Letterman show, and you do the interviews, and that's how you get out there.

To be on set with Tom Hiddlestone and Hugh Laurie is just fantastic. But during 'Homeland,' I was on set with Claire Danes and Damian Lewis, so I'm used to working with big hitters.

I've been acting for 27 years, and anonymity has always been a part of what I do. Of course you get recognised every now and again, but 'Homeland' pushed me into a completely different strata, and that took me by surprise.

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.

There is but one stage for the peasant and the actor.
