Rehearsals are one of my favourite things in the world.

'Sherlock' is one of the biggest things I will do, ever - we could never have predicted that level of insanity around the series.

There's a difference between the parts that I play and who I am and who people think I am. There's quite a big discrepancy sometimes between those things.

To my mind there are not enough things that show the Nazis as human, as smart people, charismatic people, who are not inhuman naturally. But who are able to be fantastically inhuman when they choose to be.

I think what 'The Hobbit' and Middle-earth deal in are quite universal and timeless themes of honour and love and friendship... so they're things that do resonate with people.

I think when see you a character on the screen who is actually being touched by the world, and the stuff is actually landing on him, it makes you empathize.
