Coming to theaters on November 25 is The Good Dinosaur, which may be Pixar's most difficult project. Originally slated for release in 2014, the film experienced production problems toward the third act to a point where the whole film had to be scrubbed and the entire voice cast had to be changed after original director Bob Peterson left the project. Peter Sohn (Partly Cloudy) stepped in to finish the film. And here's a first look at the final product.
