I'll always do 'Sherlock' - it's something I'm not going to give up on.

It's difficult because nothing's preordained by plan and you can't control it. That's one of those joys and thrills and nerve-racking realities of being an actor. A lot has to do with luck, no matter what your talent or contribution can be.

My mum and dad had worked incredibly hard to afford me an education.

I feel that TV and film feed off each other well. It's more in the perception of the viewer than it is of the actor.

Honestly, it's very satisfying, and I'm very, very happy about how successful the last few years have been... It's great for the people who supported me early on to see the success I'm enjoying now.

Cumberbatch - it sounds like a fart in a bath, doesn't it? What a fluffy old name. I can never say it on a Monday morning. When I became an actor, Mum wasn't keen on me keeping it.

I've realised now that the reality of children is you have to be in the right place with the right person.
