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

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 dont think any actor has the luxury of knowing exactly what scripts are going to turn out well and what ones arent. It would be wonderful to have that particular skill, and maybe people like Tom Cruise have it more than most, but you go into each project hoping that a good, if not great, film will come out the other end.

I'd go anywhere to work, so long as it's worth it.

Some people can handle fame, some can't.

You're trying to bring a character to an audience, and tell stories. That's what we're all trying do.

I always know I can die at any moment.
