Honestly, it's very satisfying, and I'm very, very happy about how successful the last few years have been... It's great for the people who supported me early on to see the success I'm enjoying now.

Even the cerebral characters I play seem to have physical quirks. They're all "physically inhabited," for lack off a better expression. For instance, Sherlock Holmes has very particular physical gestures which are drawn out in such detail.

There was a moment of extraordinary humbleness and humility and pride, as well, with my father when he turned to me - and I think it was after I played Salieri in "Amadeus" at university. And he said, You're better than I ever was or ever could be, you should do this for profession. You'd have a good time.

[on BBC's Sherlock] It's a rare challenge, both for the audience and an actor, to take part in something with this level of intelligence and wit. You have to really enjoy it. It's a form of mental and physical gymnastics.

The generation now below me were born into a world where if you're a kid with raw talent now, you can roll in and land a lead in a Scorsese film. You don't have to have prove yourself by working up the ranks, doing the classics, and getting the canon under your belt in the way the great Sirs and Dames of mom and dad's generation - the [Ben] Kingsleys and [Helen] Mirrens and [Anthony] Hopkinses and people of that ilk.

I think now with fundamentalists, people who treat belief with a total lack of humor or empathy for any other viewpoint than their own - they, to me, are the enemy. And those people are born out of desperate extremes.

[Sherlock Holmes] has moved from being someone who was sociopathic, work-obsessed and slightly amoral, into being someone who has a certain degree of a private life, which is very, very private, with The Woman, or Irene Adler.
