The story follows the two sea monsters, their adventures with their human buddy, and their love for Vespas. According to the official synopsis, Luca is a coming-of-age story much like a large body of Pixar's work, including Up, Brave, Coco, and Onward.
In addition to Tremblay, Grazer, and Berman, Luca also features the voice talents of Saverio Raimondo as town bully Ercolé Visconti, Maya Rudolph as Luca's mom Daniela, Marco Barricelli as Giulia's dad Massimo, Jim Gaffigan as Luca's dad Lorenzo, Sandy Martin as Luca's grandma, and Giacomo Gianniotti as a local fisherman.
However, the voices are only half the story. The movie also draws inspiration from authentic towns on the Italian coastline.
In conversation with Condé Nast Traveler, production designer Daniela Strijleva revealed that the fictional town of Pontorosso was created using the best parts of every one of the five real towns in Cinque Terre.
