I'm a massive comic book fan. I was buying weekly installments of "The Watchmen", and "From Hell", and "Parallax" and "Johnny Nemo". I was a huge comic book fan as a kid and I still am. Me and my youngest son are both comic book nerds together; make models and stuff.

When you suddenly appear on the scene and you are the new face, everything centers on you. I experienced this in my mid-20s and I found it rather hard.

The only film I ever made for money was something called Music From Another Room, which I really didn`t like.

You can compare Holmes and Watson to great Shakespearean characters, in a way. They've been played by hundreds of actors over the years, and each one is a different interpretation - the source material can take that form of interpretation.

I'm not Tom Cruise. Very few British actors are. If you look at the body of work I've done it's pretty obvious I'm not going to make a 'Mission: Impossible.'

I feel more and more at ease, because I think the older I get, the less pressure there is. People say, 'Well, he's not cutting edge because he's not in his twenties, so he's not expected to be.'

When you got source material, whether it's a play or a book - a great writer often appreciates being adapted and developed. It's like when you go see a production of a great play and they are always different. There is always room for interpretation.
