Maybe it's because I was an only child, but I've always wanted kids.

Being on set is quite difficult, because it's so big and you've got to try and relax, which isn't easy when you know you're in a massive film. I was terrified for quite a long time.

I know that might sound perverse because I played Julian Assange but, honestly, I don't think it would be fair for me to judge the man. I realize that makes me a bit of a hypocrite because I was portraying him a certain way, but we were always open to the fact that this was an interpretation, not any kind of exact evidence of who the man was.

I think I'm a very good driver. Apparently, the cause of road rage - as with most anger - is some kind of superiority complex, which, god knows, cars foster.

Sometimes being away, on location, I feel like I'm away for much of my own life. I want to be better at staying connected.

One of the first roles I had on stage was with a brilliant director in a brilliant play with a brilliant cast, but I just couldn't find my way into the heart of the character. I found myself straining a lot. When it started. I felt lost. That was the Eugène Ionesco play Rhinoceros. I don't think I was prepared for that. I don't think I had the full tool kit to do it justice. It's a very difficult play, it's an extraordinarily difficult part, and I never felt I really got it right. Far from it. To a degree, Hamlet was the same.

There are other people who don't mind shouting from the pulpit and being judged for it, and they do a hell of a lot of good - real, on-the-ground, life-changing good. So I think it can sometimes be a balancing act.
