The world of The Good Dinosaur is one in which the mass extinction that killed the dinosaurs never happened, and now humans and dinosaurs coexist.
That's self-evident this trailer and the brief teaser Pixar has put out for the upcoming film so far. What's less apparent, thanks to some clever cuts, is that in this boy-and-his-dog story, the boy is a dinosaur and the dog is a boy.
But who cares how this trailer disguises the fact that Arlo the dinosaur talks and his pet human Spot doesn't? The film still looks beautiful.
