The first trailer for The Good Dinosaur gave us a small tease of what’s to come from Pixar’s latest, revealing only a tiny portion of the plot and lacking any dialogue. Though it did give us a look at the gorgeous North American-inspired landscape the animators created just for the film.

Now Disney has released a full theatrical trailer for the film, which reveals a more detailed plot, and the relationship between Arlo, the dino-sized protagonist of the film, and his friend, Spot, a tiny fearless human boy. Check the trailer and a newly released image out below.

Pixar’s The Good Dinosaur has had its share of production problems in the past. The first sign of trouble was when Bob Peterson was a no-show at D23 Expo in 2013. Due to some issues with the story, Peterson was taken off the project, and replaced by Peter Sohn (Pixar animated short Partly Cloudy). At the time, the film had already cast its voice talent, which consisted of Lucas Neff (Raising Hope), John Lithgow, Frances McDormand, Neil Patrick Harris, Judy Greer, and Bill Hader.

But we are now learning that The Good Dinosaur is getting a major voice cast overhaul, and everyone except McDormand has been replaced. Some of the incoming talent includes, Anna Paquin, Sam Elliott, Jeffery Wright, Steve Zahn, and more. Check out the new cast below.
