When you start getting jobs, and see your mates from drama school, you don't really want to talk about it, because you have this innate sense of guilt that it's not fair that others aren't doing exactly what you're doing. I do have that.

When are you ever settled enough to have kids?

I tell my wife all my secrets.

Fame is a weird one. You need to distance yourself from it. People see a value in you that you don't see yourself.

Actor is an odd profession, and sometimes people get jealous, but I haven't really experienced any of that. Everyone's been really happy for me, which is really, really great.

Doctors and nurses do crazy hours and keep an ideal afloat through the love and care that they have for their craft and their patients and the institution of the NHS. We should be very proud of it.

I am also full of admiration for Chelsea Manning [formerly PFC Bradley Manning]. Regardless of which side of the argument you're on, he stood up for something he felt wasn't right. That was an extraordinarily brave thing to do, and I think he was unfairly punished for it. It's a really big deal what he did, and he did it for the betterment of all us, including the soldiers on the ground, as well as the civilians caught up in those conflicts.
