Andrew Stanton co-wrote the Toy Story movies, Monsters, Inc, Finding Nemo and WALL-E. He also directed the last two. What I'm saying is, in the playground of animation, Stanton is on the big toy.
Here he's interviewed on Fresh Air.
As if the credits I mentioned up top there weren't enough, Stanton was the voice of Crush in Nemo & also Exec-produced Ratatouille.
