I'd love to meet Julian [Assange], and time permitting, and his will permitting, I'm sure it will happen at some point. Even though he's been very critical of the film [The Fifth Estate], he's been very polite about me and my work, and I feel the same way about him.

I've said for quite a long time I'd like him to have a different haircut. I quite like my hair being short. You know, we've been away two years, let's f*** around with his outfit, let's f*** around with his haircut, let's do something different.

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. If anything, I'd like Gary Oldman's career: he's the perfect example of it. I've love to have a really broad sweep of characters - to be able to do something edgy, surprising and unfashionable.

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

I still find to give an interview to be difficult, as any person who deals with the press will tell you. That's why it's nice, with this one, to talk to a friend. But sometimes with a coffee and a friendly smile, I suddenly start talking without thinking about how it's going to be read.

I want to be able to play trailer-bound fatties in a Judd Apatow comedy.

The more charming person is the person who admits the other person is more charming.
