The Luca cast helps to deliver yet another charming and winning movie from the filmmakers at Pixar. Luca's cast is led by Jacob Tremblay as the titular character: a sea monster who discovers he can transform into a human boy when he leaves the water. Alongside his new best friend Alberto (Jack Dylan Grazer), Luca explores the nearby Italian town of Portorosso and tries to keep his true nature hidden from the local humans. The Luca cast of characters includes a mix of established cast members with younger talents stilli n the early stages of their career, playing a range of entertaining antagonists that make Luca one of the best Pixar movies of the last decade.

Directed by Enrico Casarosa, Luca streamed on Disney+, continuing a new era for Pixar releases hitting streaming instead of the big screen. Despite the unusual release, Luca became a hit with audiences and critics with this original feature film. Luca's coming-of-age story is a small-scale and infectiously joyful adventure that embraces the childhood innocence of Luca and his friends, and the beautiful surroundings of the Italian Riviera. However, Luca wouldn't have nearly the same level of charm if it wasn't for its stellar and immaculately well-selected cast. Here's a guide to the characters of Luca, and what their voice actors look like in real life.

Jacob Tremblay as Luca Paguro

Luca Jacob Tremblay

Luca Paguro is a 13-year-old boy who also happens to be a sea monster. He has lived in the ocean for his entire life, herding goatfish with his parents in their underwater farm. But his curiosity about the surface world leads him to stray away from his home, and when he meets another sea monster called Alberto, the two of them go on an adventure to the world above the waves. Jacob Tremblay found his breakout role in the Oscar-winning drama Room alongside Brie Larson. Since then, he has appeared in Doctor Sleep and Good Boys. Tremblay will next be seen in the remake of The Toxic Avenger and with voice Flounder in the live-action Disney remake of The Little Mermaid.

Jack Dylan Grazer as Alberto Scorfano

Luca Jack Dylan Grazer

Protagonists Luca Paguro and Alberto Scorfano meet by chance while Luca is exploring, and quickly become best friends. Alberto is a year older than Luca and more experienced at sneaking away to the surface. Always on the lookout for adventure and excitement, Alberto considers himself to be an expert on the human world and human behavior - though some of his knowledge is a little off. Jack Dylan Grazer is known for playing Eddie Kaspbrak in the IT movies and Freddy Freeman in Shazam! and its sequel Shazam! Fury of the Gods. He will next be seen in the television adaptation of The Spiderwick Chronicles.

Emma Berman as Giulia Marcovaldo

Luca Emma Berman Giulia

Though she might not be a sea monster, Giulia is another misfit who struggles to make friends with the human kids of Portorosso, especially since she only lives there in the summer. She finds two kindred spirits in Luca and Alberto, who don't mind that she's loud and bold and speaks her mind. With their help, she hopes to win a local race, the Portorosso Cup. Luca is the feature film debut for Emma Berman, who has previously appeared in a number of stage shows and in the voice cast of the Netflix children's series Go! Go! Cory Carson.

Saverio Raimondo as Ercole Visconti

Luca Saverio Raimondo

Ercole Visconti is Portorossi's resident bully: a spoiled, narcissistic, Vespa-riding jerk. With the help of his two sycophantic sidekicks, Ciccio and Guido, he annoys the townsfolk and makes a target of outsiders like Giulia, Luca, and Alberto. Ercole is also the reigning champion of the Portorosso Cup, the race that Giulia is determined to win. Though he is probaly the least intimidating Pixar villain to date, he is a hilarious addition to the movie. Saverio Raimondo is an Italian stand-up comedian known for his Netflix comedy special Il Satiro Parlante.

Maya Rudolph as Daniela Paguro

Luca Maya Rudolph

Daniela Paguro is Luca's mom, an extremely protective goatfish farmer who doesn't want her son going anywhere near the surface. Her disciplining of Luca comes from a place of love, even if it's not always expressed in the most loving way. Maya Rudolph is a comedic actress known for her roles in The Good Place, Bridesmaids, and Big Mouth, as well as being a regular Saturday Night Live cast member. Rudolph will lend her famous voice to some notable future projects including Teenage Mutant Ninja Turtles: Mutant Mayhem and John Krasinski's Imaginary Friends.

Marco Barricelli as Massimo Marcovaldo

Luca Marco Barricelli

Massimo Marcovaldo is Giulia's dad, and while his size, mustache, and sparing use of words make him come across as very intimidating, he has a kind heart and deeply loves his daughter. He is a fisherman and deftly skilled with a knife, so Luca and Alberto are understandably afraid of him finding out their secret. Massimo is accompanied by a pet cat, Machiavelli, who also has a mustache. Massimo Marcovaldo is an Italian stage actor who also appeared in the NBC series The Book of Daniel and voiced characters in video games Clandestiny and Manhunt 2.

Jim Gaffigan as Lorenzo Paguro

Luca Jim Gaffigan

The other heavily mustachioed dad in Luca is Luca's own father, Lorenzo. Though he shares his wife's concern for finding Luca, Lorenzo is more bumbling and easily distracted. In particular, Lorenzo is obsessed with his hobby of raising pedigree crabs, but has good intentions and loves his family. Gaffigan is a stand-up comedian and actor who is also the star of comedy series The Jim Gaffigan Show and voices Van Helsing in the Hotel Transylvania movies. He appears in another Disney+ project joining the cast of Peter Pan & Wendy as Captain Hook's henchman Smee.

Sacha Baron Cohen as Uncle Ugo

Sacha Baron Cohen Luca

Ugo is Luca's uncle, an odd-looking deep sea creature who lives in the trenches of the ocean. When Luca's parents find out that their son has been to the surface, they panic and send Ugo to reign him in, but the scary-looking sea creature only drives Luca further away. Sacha Baron Cohen is known for playing the titular character in the Borat movies and recently appeared in Aaron Sorkin's film The Trial of the Chicago 7. He will reportedly join the MCU as Mephisto, first set to appear in the Ironheart Disney+ series.

Everything We Know About Luca 2

what to expect from Luca 2

Given the success of Luca, it's entirely possible that Pixar could move forward with a sequel at some point. Luca 2 hasn't been announced, but Casarosa has said that he feels optimistic about the possibility of a sequel, or even a series on Disney+. The streaming service already offers an original Luca short, Ciao Alberto, which offers the same humorous and heartfelt vibe of the original movie and clearly illustrates how a sequel could continue to explore the characters' lives.

Luca 2's cast would probably be mostly the same, and its story could flesh out Luca's experience at school, bring Alberto to Genova for a visit, or bring Luca and Giulia back to Portorosso for a subsequent summer. It's unlikely that Luca 2 would arrive earlier than 2024-2026 given the first film's timeline, and this gap could open the possibility of telling Alberto, Luca, and Giulia's stories once they get a bit older. Whatever the case, a sequel to Luca would likely be well-received.
