I'm lucky enough to have a kid with me who is actually really intellectually up with what's going on in the world and actually puts his money where his mouth is and goes and does something about it; he goes and talks about it. It livens you up a bit and it brings you into the 21st Century.

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.

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.

But then when you go through the process of making the film and you sit in the cinema two years later and your jaw hits the floor, it's quite sad in a way because you're looking at yourself - facially anyway - and see the way you looked when you were 20.

There is something about silence and being in the middle of nowhere that is really very attractive.

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.
