We got a sneak peek last month, but the first official full-length trailer for The Good Dinosaur is finally here. The new Pixar movie, which hits theaters on Thanksgiving, begins with a simple premise: what if a giant meteor hadn’t slammed into the Earth and killed all the dinosaurs?

The trailer introduces us to an Apatosaurus named Arlo who strikes up an unlikely friendship with a human boy. And because this is Pixar, you can expect this story to play out against a truly stunning animated backdrop.

The Good Dinosaur‘s all-star voice cast includes Jeffrey Wright, Steve Zahn, Anna Paquin, Sam Elliott and Frances McDormand.

Correction: The original version of this article misstated the cast of The Good Dinosaur.
