The Good Dinosaur released a first full-length trailer Tuesday.

The preview reimagines history and presents a world where dinosaurs never went extinct and co-existed with humans. The movie is based on the idea "a single moment can change everything" -- namely, the Earth never being hit by the asteroid that devastated the planet.

Raymond Ochoa voices Arlo, an Apatosaurus who is unintentionally separated from his herd. The character befriends a human cave-boy he names Spot (Jack Bright), and the pair team up to make their way back to Arlo's family.

The Disney-Pixar animated film is directed by longtime Pixar artist Peter Sohn, and opens in theaters November 25. Jeffrey Wright, Frances McDormand, Steve Zahn, Sam Elliott and Anna Paquin also have voice roles.
