I've seen and swam and climbed and lived and driven and filmed. Should it all end tomorrow, I can definitely say there would be no regrets. I am very lucky, and I know it. I really have lived 5,000 times over.

I genuinely don't know Julian Assange well. To authenticate an opinion, I really would have to meet him.

[Doctor Strange ] is slightly more specialised than Spider-Man or Superman or Batman, but he's very loved by people who know him.

Sherlock [Holmes] is on the side of the angels, but don't think he's one of them. He uses similar means, but it seems to be for a better purpose, one would hope.

There's a huge amount of footage of Julian [ Assange] online, but he's usually in presentation or defending mode, talking about his cause, or the revelations which Wikileaks have brought about. There's none of Assange relaxing or in private mode. There's none of the personality I tried to give him behind closed doors [in The Fifth Estate ].

I suppose my bodily proportions are quite flattering. I'm ripped, doing something I wouldn't normally do with my body, or having done to it, involving Watson.

I would love to just have the work do the talking. We're in positions where people ask us questions; they want to know about more than just the work. And it can go into areas where I've completely shot my mouth off, whether it's too much about my private life or being too opinionated about things in the world. I think the better thing to do - I've learned this from people far wiser than me - is to do very good, quiet work behind closed doors.
