I really wouldn't want to live in America. I found New York claustrophobic and dirty. I missed England when I was there, simple things like smells and the British sense of humor.

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 think Danny Boyle's got it in his head that we all still look too young (to do a 'Trainspotting' sequel.) But, I mean, I don't look like anyone I play, anyways, so I don't really know where that comes from. Because, you know, you change yourself for the roles. I'm actually not Scottish, either!

I always know I can die at any moment.

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

I don't want to talk about the specifics of other people's performances compared with my own. I'd never do that.
