'The Good Dinosaur' Trailer Imagines World Where Prehistoric Creatures Survived

The animals roam free, as the preview shows an asteroid missing Earth.

Disney/Pixar released the first extended look at its upcoming animated film The Good Dinosaur, which imagines a world in which the asteroid that's believed to have killed the dinosaurs actually missed Earth.

The trailer sets up the universe with a humorous scene in which the dinosaurs watch passively as the asteroid whizzes by, changing the course of history. The Good Dinosaur centers on a lost dinosaur that meets an orphaned boy.

At Cannes, Pixar's chief creative officer John Lasseter said of the film: "This is a boy and a dog story, but the roles are reversed.”

He added that the film is “striving for a very unique tone, unlike any animated film [ever] made." After showing the Cannes audience some animated nature scenes that looked like they were real, Lasseter said: "It’s not going to be your average backdrop for a film."

The teaser trailer for the Peter Sohn-directed film doesn't feature any of the star-studded voice cast on board including Neil Patrick Harris, Bill Hader, John Lithgow, Frances McDormand and Judy Greer. The film, which originally was slated to open last year before original director Bob Peterson exited the project, now will hit U.S. theaters on Nov. 25.

The Good Dinosaur is Disney/Pixar's second film due out this year; it follows Inside Out, which hits theaters on June 19.
