I think you always learn something in every character you play onstage, either personally or creatively.

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.

People are fascinated by evil because it's mysterious and it doesn't seem to have a rational behind it.

I've auditioned for normal characters. But I never get cast.

Normally death scenes are good, if you have a significant death scene and it means something it's like the audience has an attachment to you being killed that's a good thing.

You get ideas from other people all the time.

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.
