It is now confirmed that "Up" co-helmer Bob Peterson has been removed as director of Pixar's 2014 feature "The Good Dinosaur". Pixar Animation Studios president Ed Catmull says:
"All directors get really deep in their films. Sometimes you just need a different perspective to get the idea out. Sometimes directors... are so deeply embedded in their ideas it actually takes someone else to finish it up. I would go so far as to argue that a lot of live-action films would be better off with that same process."
A replacement helmer has yet to be named, though members of the famed Pixar brain trust are currently steering the project.
The likes of John Lasseter, Lee Unkrich, Mark Andrews, and Pete Sohn are overseeing different sequences to make sure the film meets its May 30th 2014 targeted release.
