I wouldn't change a thing in my life, even if I could. What you go through makes you who you are and that's fine.

Every job I take, within minutes Im thinking, I cant do this. I think its what makes me work. People think I just swagger in and do it. But I doubt myself all the time. Its what pushes me, what makes me work harder. The older I get, the less I take for granted.

The other thing is that when people mention computers - and I'm pretty much the same - they find it hard to comprehend that there's a performance there. They look at it as something that's just been made by a computer but in a way the difference is that when you make a normal film - and I'm simplifying it here - you put on the make-up and you put the scenery in before you start shooting, but with this you still perform in the same way but then you put the make-up on after, along with the costumes and scenery.

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.

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.

As a man, there's a part of me that feels I should still be going out and doing a proper day's work.

Sometimes you also work with people who don't explain or express to you what they're actually looking for from the shot but you haven't got that problem with this because whatever you're going to do, whether it's good or bad, will get picked up. So, in that way I guess it's pure cinema.
