Sure, there’s another dinosaur movie thundering into theaters this weekend. But in other dino-mite news, Disney-Pixar’s The Good Dinosaur has revealed the voices who are behind its prehistoric heroes. The film asks the Sliding Doors-like question: What if an asteroid never hit earth and wiped out the dinosaur? In this movie Arlo, an Apatosaurus (look it up, kids!), is separated from his family and meets a boy — whom he he names Spot — along the way.

“We were lucky to work with a number of incredible pros along the way and our story ultimately led us to this amazing and talented group,” said the film’s director, Peter Sohn, in a statement. “We’re all taking this journey with Arlo, and it’s been a privilege to see these performers bring our characters to life.”

On board is Raymond Ochoa (The Night Shift) who provides the voice of Arlo; Jack Bright (Monsters University) as Spot; Jeffrey Wright as Arlo’s father; Steve Zahn (a pterodactyl named Thunderclap); AJ Buckley (a T-Rex called Nash); Anna Paquin (a T-Rex named Ramsey); Sam Elliott (yet another T-Rex named Butch), Frances McDormand as Arlo’s mother and Marcus Scribner as Arlo’s brother.

It’s a bit of a shake-up from what was originally slated in 2013—back then Bill Hader, Neil Patrick Harris and Judy Greer were all attached and Bob Peterson, who came up with the story, was on board to direct. But now it’s full dinosaur ahead and we’ll see the film on Nov. 25.
