Savion Glover is the dancer who was motion captured for the lead penguin in Happy Feet. While his credit on the film is small and he isn't being publicized in the advertising, he's still getting media attention. There's a N.Y. Times article here which expresses mild outrage at the smallness of Glover's credit and a Washington Post article here and an L.A. Times article here both talking about Glover's contribution.
The Washington Post article had a quote that caught my eye.
"I knew even the greatest animators in the world would take a lifetime to pull off the nuances of dancing that a gifted dancer is able to pull off," says "Happy Feet" director George Miller, speaking by phone the other day from Sydney, in his native Australia.It's not enough to praise the dancer. Miller has to knock the animators down to build the dancer up. Can you imagine anyone in live action saying that it would take an actor a lifetime to pull off the nuances of motion that a talented animator could pull off?
If animators don't trumpet their skills and accomplishments, nobody else will. If you don't, you deserve whatever happens. Publicity is the coin of the realm. It doesn't do any good to be brilliant if nobody knows you are.
