When you're playing a character, you don't really want to have an opinion about where you're going to end up. Otherwise, you can't really stay in the moment and in your character.

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've never taken myself too seriously, I'm not into that.

I always know I can die at any moment.

I like to play different types roles, but I'd like to do a comedy next.

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.

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.
