Sometimes when you're making a film and something happens during a scene that you've just thought of, it can be missed if the wrong lens is on or if you're shooting in the wrong direction but this [performance capture] doesn't miss a thing. So, you might do something that's genius - very rarely, admittedly - but it doesn't miss it.

I know I've got to pay some tax, but I hate the fact that they collect millions of pounds a day from the congestion charge and I don't see anything or anyone benefitting from it. Where are the new hospitals?

You've always got to have an imagination in the game we're in but it explodes on this. You get to try the costumes on before you start and feel the weight of them, which is great. But then you're opposite some of the greatest actors in the world and away you go. You find your imagination takes over without you really even thinking about it.

I love to be the lead, but you can't always be the lead.

When somebody meets me in the street, they say, 'Hello, how you doing?' And I say the same back. It's just two minutes of your time and it's alright. I don't like people taking liberties when I'm with my family, but mostly people are really polite and that's lovely.

Working with Scorsese was an absolute dream, and one of my favourite ever jobs was 'Beowulf' because it was just pure acting. Your imagination explodes as you try to imagine you're fighting a dragon or whatever.

I had a very real fear of spiders until one bit me. I got bitten by a redback spider in Australia and I've never been frightened of them since. Maybe I've turned into Spider-man.
