Ash Brannon directed "Surf's Up" and co-directed "Toy Story 2," two of my favorite animated films. He took on quite a challenge writing and directing the endearing new international production "Rock Dog," inspired by a Chinese graphic novel about a sheepdog from Tibet who wants to be a musician. I was lucky to get a chance to talk to him about it.
Like the surfing penguin story "Surf's Up," "Rock Dog" is the story...
