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.

By being with my kids. I'm like a lion who hunts and comes home to be looked after and sleep. I think girls tend to be drawn towards their dad. I'd love to have a son, but I have three kids who are great - three geezer birds and that's all I need to worry about.

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've never met a politician I haven't wanted to walk away from, and I've yet to hear a politician speak and actually believe the words coming out of his mouth.

I'm away so much I've had to learn to cook, and I find it relaxing after filming. I make stews and liver and bacon, and an Italian mate taught me how to make a mean puttanesca sauce.

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