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

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.

Very few movies I've done I regret being involved in.

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

I think at some point every actor has practiced their acceptance speech while they're having a shower. It's fun.

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 remember thinking, 'I'll audition just once and if it doesn't work out I'll never think about it ever again.'
