I know he [Julian Assange] is a man of fierce determination, and now living under the strain of house arrest in the Ecuadorean embassy as a "political exile," as he calls himself.

I understand from those who adore him, he [Julian Assange] has a great sense of humor which rarely gets an airing because he's dealing with such serious issues.

I was very nervous about doing the Entertainment Weekly cover, because I thought, "Okay, this is the first taste, this is the first visual moment." By then I obviously knew a lot of the more iconic moments in his comic history, but still it's me. It's not a drawing, it's not an artist; it's me and I'm kinda frightened, but it seemed to go down.

Sometimes during a conversation with a journalist - where you are answering things you never normally talk about, not even with some of your closest friends - you end up being quite confessional, and you don't think about the amplification of that. No matter how fancy these journalists are, they have editors or political leanings behind their publications, which means that, basically, they're going to shape what you've said into an article they've already written. So you have to be really careful with your words.

That's something I have to work on: to separate what really matters, to conserve energy by not worrying about what other people think. When I walk through that door, it's about home. If I didn't do that, I'd become consumed by one thing only and damage the people who love me. And it would damage the work.

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'll always do 'Sherlock' - it's something I'm not going to give up on.
