The first time we did cavalry charge I was so breathless with excitement I nearly fell off the horse. I actually saw stars in front of my eyes and thought I was going to faint. The second time I had a bit more control but was still giddy with excitement. And the third time I was an emotional wreck. I had to really try hard not to cry.

I just increasingly enjoy the quiet moments when I can be on my own with my friends and family, or with a book, having a live experience. That's really what I crave, and I always have done.

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.

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 want to be able to play trailer-bound fatties in a Judd Apatow comedy.

Anyone who works in the NHS has superpowers. It's a miracle, it is magic.

I always get self-conscious about what I look like in a film, but less so if I'm a character very far removed from who I am. Then I just worry about the performance, and that's equally an odd experience.
