The Good Dinosaur

A new untitled Dinosaur film, or The Untitled Pixar Movie About Dinosaurs as Bob Peterson and John Walker humorously titled it, will be released on November 27, 2013. It will be directed by Bob Peterson and co-directed by Peter Sohn. Enrico Casarosa, director of La Luna, will be head of story.

Plot
"What if the cataclysmic asteroid that forever changed life on Earth actually missed the planet completely and giant dinosaurs never became extinct? This hilarious, heartfelt and original tale is directed by Bob Peterson (co-director/writer, Up; writer, Finding Nemo) and produced by John Walker (The Incredibles, The Iron Giant)."

Development
It is assumed that the Dinosaur project started sometime in 2009. When a promotional video for Up called Up: B-roll 1 was released, many fans noticed 4 stand-out images in the background of sculptor Greg Dykstra's office. The top image is a clay sculpture of an herbivorous dinosaur with a person standing next to it. Below it are two more images of clay sculptures of a boy. The fourth image, not clearly visible, is a drawing of the same or another herbivorous dinosaur.

The film's current release date of November 27, 2013 was first announced in June 2011. Not long after, the plot, director & co-director, producer, and other small details were announced at the D23 Expo on August 20, 2011. Bob Peterson and John Walker humorously titled the film The Untitled Pixar Movie About Dinosaurs and even created a logo for the mock title.
