"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."
