'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.

The world of 'Sherlock Holmes' and the world that we live in now is big enough to take more than one interpretation.

If people ask, 'Are you Sherlock Holmes?', it's horribly naff, but I say, 'I'm not, I just look a bit like him' - which is how I feel. There are bad attributes of his that I really don't share!

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

I was thrilled with how the first series of 'Sherlock' was received. It was such great fun to film, which makes it so rewarding when something you enjoy is so well received.

I got live tweeted once by someone who was opposite my home in some rented accommodation. He was actually describing on twitter what I was doing. 'I took a shirt off, I went to the window, I put a shirt back on... ' And I've got blinds in my flat!
