Whenever I tell people I'm a misanthrope they react as though that's a bad thing, the idiots. I live in London, for God's sake. Have you walked down Oxford Street recently? Misanthropy's the only thing that gets you through it. It's not a personality flaw, it's a skill.

You sort of perform your personality, I guess, to everyone on some level.

I'm a worrier. In the UK, if I'm known for anything, it's sort of for being cynical.

I've always had a bad attention span.

What we were also trying to do is vary the tone slightly across the season of Black Mirror, because there are six stories this time around, so you don't want it to just be the devastating, bleak-em-up.

As long as we've still got crazy "what if" ideas, we can continue [Black Mirror]. It's outpacing reality that's probably the challenge.

Online you're encouraged to perform one personality for everyone.
