Plot details are vague, but we know that it centers on the idea that the asteroid that wiped out the dinosaurs never actually hit earth, and dinos are still walking amongst us today. Neff will be voicing the lead character named Arlo while Lithgoow and McDormand will be playing adult dinosaurs named Poppa and Momma. Hader, Harris and Greer will play their children.
John Lasseter and John Walker are producing.
After most recently releasing “Brave” and “Monsters University”, Pixar is currently in production on the sequel to “Finding Nemo”, “Finding Dory.”
