An untitled original Pixar film about a "suburban fantasy world" was first announced at the 2017 D23 Expo. It will be directed by Dan Scanlon and produced by Kori Rae; both of whom previously worked on Monsters University.
Set in a humanless world of elves, trolls, sprites, and “pretty much anything that would be on the side of a van in the ‘70s,” the movie follows two teenage brothers whose father died when they were young; now, they’re “on a quest through this mundane, modern fantasy world to somehow find a way to spend one last magical day with their father.”
Dan Scanlon also described more details about the “modern suburban fantasy world” the film inhabits. It’s a world where magic existed long ago, but because of difficulty and complication, people simply lost interest and instead created machines to do both the magic and the mundane. “The world is basically a mix of the fantastic and the everyday,” Scanlon explained as concept art showed slices of recognizable suburbia, albeit with goblins and creatures. “There are mushroom houses that line the streets with satellite dishes sticking out the top of them and a minivan parked in front of each one. There are no humans… but there are unicorns everyone. They’re basically rodents, possums eating all the trash out of your bins.”
