Success is never bad in Hollywood. It is what you do with success that will dog you.

Evil is a really tough concept for me. The idea of a villain that is bad for bad's sake seems kind of absurd.

Action to me is something very fun to shoot.

When you sit and watch the film with an audience, the focus groups and the cards and all of that is the less what you're worrying about. When you watch a film with an audience you see what is working and what's not working.

I've looked at all of Hitler's speeches thinking that there's gotta be one where he's 'I'm Hitler!', but there weren't any. His speeches were all about hope and prosperity - he ran on a platform of peace and prosperity. Hitler speeches that makes him sound like a villain are pretty hard to find, he was very detached from what he was doing, he kept himself compartmentalised from it.

You know that certain things that you use in the film are going to be shown to audiences five hundred times before they ever sit down to watch the movie. So you have to kind of modulate what can I do to give marketing enough material but that I can still withhold certain things so that it's fresh and surprising for the audience coming to see the movie.

The biggest challenge is not coming up with the stunt, the biggest challenge is designing a sequence around it that sort of justifies its existence.
