Because Naughty Dog relies on their facial team to hand animate the faces of each game character and they do such a remarkable job, I think you can be more realistic with your acting. It gives the story and what's happening to you the feeling that it's a game.

When we did the first 'Uncharted,' we weren't able to capture the audio with the performances. We would go back and do A.D.R. - Automated Dialogue Replacement - in which you would hear yourself and then repeat your line. Even when we were doing that, there was a slight disconnect because you were trying to recreate a performance.

There's something known as the Uncanny Valley where things look a little too real and you're not quite sure what you're looking at. It becomes weird like it did in 'The Polar Express,' where the eyes seem so realistic, and yet you know it's animated.

My first motion capture game was with Sony - 'NBA: The Life.' It was very ahead of its time. Brandon Akiaten, he was the writer and director. He had a real vision of what this game was meant to be; it was a basketball game where I was the Jerry Maguire sports agent type guy. And it was great!
