"The Good Dinosaur" asks the generations-old question: What if the cataclysmic asteroid that forever changed life on Earth actually missed the planet completely and giant dinosaurs never became extinct? The film is a humorous and exciting original story about Arlo, a lively 70-foot-tall teenage Apatosaurus with a big heart. After a traumatic event rattles Arlo's tranquil community, he sets out on a quest to restore peace, gaining an unlikely companion along the way-a young human boy named Spot.
