The world of 'Sherlock Holmes' and the world that we live in now is big enough to take more than one interpretation.

I feel that TV and film feed off each other well. It's more in the perception of the viewer than it is of the actor.

I've been very lucky at what's happened in my career to date, but playing something as far from me as possible is an ambition of mine - anything from a mutated baddy in a comic book action thriller, to a detective.
