Pixar’s next original film doesn’t even have a title yet, but it’s already making D23 audiences cry.

During the fan convention’s animation panel on Friday, John Lasseter introduced director Dan Scanlon to unveil details about a new original film on Pixar’s upcoming slate, filling in one of the cryptic untitled slots on the studio’s release schedule.

Lasseter described the film as “an adventure set in a suburban fantasy world,” and Scanlon, who helmed Monsters University, debuted concept art showing a large winged creature flying over a small town at sunset.

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.”

The movie is inspired by Scanlon’s search for answers about his own father, who passed away when he was a year old; Scanlon played a clip of a home movie recording bearing the only known preservation of his father’s voice, which he first heard as a teenager. His resultant journey trying to learn more about his parent serves as the blueprint for this film.

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.”
