Last year, 20th Century Fox released its animated Dia de los Muertos-themed film, The Book of Life, and now Pixar is prepping its own animated film rooted in the Mexican holiday tradition. As revealed at last night’s animation panel at D23, the movie is officially titled Coco, and Pixar has offered up the first plot details as well as the official poster.

Toy Story 3 director Lee Unkrich has been developing Coco, an original Pixar film based on the Mexican Day of the Dead, or Dia de los Muertos. Unkrich has been working on the film since 2012, but it looks like Pixar is finally getting the ball rolling on the long-developing project.

Disney and Pixar released statements from Unkrich and producer Darla K. Anderson to help explain the vision for the project:

“As artists and filmmakers, we couldn’t help but be drawn to the striking visuals of Dia de los Muertos,” said Unkrich and Anderson. “But it was the celebration’s core themes of family, remembrance and connection across generations that resonated within and truly inspired us. Dia de los Muertos is as singular as the Mexican culture, while at the same time completely universal in its message.

“In our story,” they continued, “the celebration of Dia de los Muertos serves as the perfect backdrop for our main character to ask where he comes from, what his place is within his family, and how families stay woven together across time through the simple act of remembrance.”

The plot is described as “the celebration of a lifetime, where the discovery of a generations-old mystery leads to a most extraordinary and surprising family reunion.”

In addition, Pixar revealed the first poster, which teases a fall 2017 release:

The studio hasn’t had too many original projects in recent years — this year brings two with the recently released Inside Out and the upcoming The Good Dinosaur, but after that we’ll be getting a handful of sequels to existing Pixar properties, like Toy Story 4, the long-awaited Incredibles sequel, and Finding Dory.
