I feel like I'm away for much of my own life.

[Sherlock Holmes] has to understand the world. That's very much John's [Watson] influence on him. But like a lot of the friendships and relationships in that world, it's born out of necessity. It makes him better. There's a pragmatism to it. It's not whimsical or sentimental. It's born out of necessity.

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.

Conan Doyle is amazing in the way he has Watson describe Sherlock’s posture, mood swings, his hand gestures, and so forth in the novels.

I had a very sparse comic upbringing - not because I was being whipped into reading Chekhov and Dickens, but I read Asterix on holidays when I was a kid, and Tin Tin was featured, I remember, for a few years.

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'm a Prince of Wales Trust ambassador, so I'm all about giving youth an education, a voice and a chance to not take the wrong road.
