I'm really not Sherlock Holmes. I look a little bit like him and sound like him.

Being on set is quite difficult, because it's so big and you've got to try and relax, which isn't easy when you know you're in a massive film. I was terrified for quite a long time.

The armoury of having any academic education does not necessarily set you up for being a good or better actor.

I thought, well, why am I giving up on my primary dream to work doubly hard, to do something as an alternative to what it really still want to?

Actor is an odd profession, and sometimes people get jealous, but I haven't really experienced any of that. Everyone's been really happy for me, which is really, really great.

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.

One of the fears of having too much work is not having time to observe. And once you get recognised, there is nowhere for you to look any more. You can't sit on a night bus and watch it all happen.
