The Chronicles of Narnia: Prince Caspian director Andrew Adamson, best known by animation fan as the helmer of Shrek and Shrek 2, talks to the New York Daily News about the use of computer animation in the upcoming Narnia sequel, comparing making a live-action movie versus an animated film like the difference between “running a sprint and a marathon – the intensity is the same, but the duration is different. In animation, you get a lot more chances; you can refine things over and over and over again.”
