It isn't every day that you get lessons on how to draw a dinosaur from a professional artist, so get your pencil and paper ready before checking out the latest featurette from Walking with Dinosaurs: The Movie. Character designer David Krentz takes us through the steps of drawing the main dinosaur character Patchi. This drawing tutorial also features insights into Patchi's look, including the reasoning behind punching a hole through this young dinosaur's head. We also see new footage from this 3D adventure directed by Barry Cook and Neil Nightingale, arriving in theaters December 20.
