Seriously, he's really good. He's most famous for having done the Beast in Beauty and the Beast
though he also did Ariel and a bunch of others.
Anywho, I just saw this lecture that he did on animation (back in 2007...I'm late to the party). It's really excellent to watch, since he covers so many important topics of animation: arcs, anticipation, exaggeration, weight, balance, timing...just watch it, and you'll be glad you did.
