For me, there are two different things that make Sherlock Sherlock. One is, you know, within the books: obviously he's a genius with an attention to detail, his ravenous hunger for all aspects of knowledge that might feed into his work. But the major thing that makes him Sherlock is his relationship with Watson - their friendship. For me, that, I guess, is the biggest side, the more interesting side than the genius.

I always know I can die at any moment.

I used a bike in London and that's it. I learnt a lot about biking, and really got into. Now I cycle regularly.

Some people can handle fame, some can't.

When you're shooting 20-odd episodes in a season, the last thing you want is for each script to be the same tone.
