Elaine and I got married in summer 1979, we went on our honeymoon and came back for the premiere of Scum. All of sudden my face was on billboards in Leicester Square and people were crowding outside the cinema, going mad about the film. It was a complete shock.

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.

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.

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

I think the difference is that Angelina didn't need any CGI enhancement and I did! You can't really think about some things too much, you just get on with it and do it. It's about the way you move and the way you sound.

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.

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