I really wanted to get out of England.

I keep mementos from everything I've done. I've got my cab driver's license from 'Happiness.' I've got a pair of glasses and a belt buckle from playing John Lennon. I've got a pair of sunglasses from playing Andy Warhol... It's all in a box in the garage.

I wasn't aware of my dad being an actor when I was young. I remember there was an Australian children's entertainer on television called Ralph Harris and when I'd say my father was an actor, kids would say, you know, 'oh, is he Ralph Harris?' And I had to say no and then they would lose interest.

One of the things that I was interested in about Moriarty was - he's so manipulative that he doesn't need to commit violence himself or kill people - he can get everyone to do what he needs to do. And sometimes they don't even know that they are being manipulated by him.

I was 17, and all I wanted to do was to get away from England and the awful, boring boarding schools I'd been going to there. The last one was taught by monks, and I couldn't wait to get out.

If you want to do your version, go off and write it. You bring your knowledge to it, and you can use that to shape it and color it, but it's someone else's version of that character. You're not actually playing the real person.
