Andrew Stanton co-wrote every Pixar feature of the studio’s first decade before directing Finding Nemo and WALL-E, both of which won Best Animated Feature. He is a writer first and describes story problems in structural terms more readily than visual ones.
WALL-E is his most ambitious work, opening with roughly forty minutes of near-silent character animation on an abandoned Earth. Getting a studio to fund that in a family film is remarkable in itself.
John Carter, his live-action feature, was a commercial failure large enough to become an industry cautionary tale, which has somewhat overshadowed a strong record.
