I'm taking a bit of a wait-and-see attitude towards 3D.

It's difficult to keep anything fresh for an audience these days. With technology being what it is people seem to know everything there is to know about a film before you've even made it.

The problem with big films is they snowball very rapidly and you can never pull back. It's a pipeline that needs to be fed.

Well, you always discover a lot in the editing room. Particularly the action, because you have to over-shoot a lot and shoot an enormous amount of material because many of the sequences have to be discovered in the editing and manipulation of it.

I have always been a huge fan of Ridley Scott and certainly when I was a kid. 'Alien,' 'Blade Runner' just blew me away because they created these extraordinary worlds that were just completely immersive. I was also an enormous Stanley Kubrick fan for similar reasons.

The term 'genre' eventually becomes pejorative because you're referring to something that's so codified and ritualised that it ceases to have the power and meaning it had when it first started.

A hero can be anyone. Even a man doing something as simple and reassuring as putting a coat around a young boy's shoulders to let him know that the world hadn't ended.
