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.

When you're a kid, 'Star Trek' is a slower burn. It's funny, it's entertaining, but it also has a maturity about it - which is its universal appeal, I think.

I think I've had very knee-jerk emotional reactions to things, and sometimes I've said things without thinking. Being overly emotional clouded my judgment.

Marvel always make it fresh so you can give it your personal twist.

Those are more universal things than some of the characters I play, who are slightly sociopathic. I keep reminding people I can do ordinary.

I'm very proud of the work I do, but I genuinely can't involve myself with an audience as early as somebody who's not part of the film can. So there's that side of theater that appeals to me, where you give something and the response to what you've created is a communion between you and the dark that contains however many people. It's thrilling not having a reflection other than through the people you're communicating with. But people ask, "What do you prefer?" and I don't have a preference. I love them both. I really do.

'Sherlock' fans are, by and large, an intelligent breed, so they've gone through my back catalogue and got what I've done, why and how I've done it. There is some obsessive behaviour, but I worry for them rather than me.
