Continuing its streak of live-action remakes, Disney is dipping its tail back into the Little Mermaid well, with a blockbuster retelling of the classic animated adventure. 

While largely being the same story as the 1989 original, The Little Mermaid remake will feature a whole new cast of familiar and never-before-seen characters and will even feature some small narrative changes to be "respectful" of the societal norms of 2023

But who can fans expect to appear in Rob Marshall's aquatic adventure? Here's a list of every actor and character set to appear in The Little Mermaid.

The Little Mermaid - Every Main Actor & Character They Play

Halle Bailey - Ariel

Starring as the titular little mermaid is American singer-songwriter, Halle Bailey. Bailey plays Ariel, the daughter of King Triton with an infatuation with the world above and the most beautiful singing voice in all the sea. After making a deal with the villainous sea witch, Ursula, Ariel is given the chance to live amongst the human world, but loses her voice and must fall in love or else she will be turned back into a mermaid. 

Bailey is best known for her Grammy-winning work as one-half of the R&B duo, as all as acting work in the hit ABC comedy Grown-ish. She is also set to star in the upcoming remake of the 1986 Oscar nominee, The Color Purple

Jonah Hauer-King - Eric

Opposite Halle Bailey's Ariel is Jonah Hauer-King's Prince Eric. Hauer-King plays a prince who falls madly in love with Bailey's Atlantean after she's come up on land to be amongst the people. While The Little Mermaid remake has been touted as "more modern" than the animated original, Prince Eric purportedly has a "very similar trajectory" to the source material.

Little Mermaid marks Hauer-King's big blockbuster break in Hollywood, after making appearances in films like A Dog's Way Home and the BBC television adaptation of Little Women

Daveed Diggs - Sebastian

Playing one of the most beloved characters in the annals of Disney history is Daveed Diggs as Sebastian the Crab. The singing and dancing crustacean serves as a close confidant of Javier Bardem's King Triton tasked with taking care of Ariel and keeping the ambitious Mermaid out of trouble. 

Diggs is best known for his work in the original cast of the smash-hit Broadway musical Hamilton and has made quite the career for himself since, starring in TNT's Snowpiercer series, Pixar's Soul, and the critically-beloved Blindspotting

Awkwafina - Scuttle

Another one of Ariel's animal friends is the eccentric seagull, played by comedian Awkwafina. Scuttle is a self-proclaimed human expert, living off the coast of Prince Eric's kingdom consults Ariel about the human world, offering (usually incorrect) expertise on what goes on above the surface. 

The Little Mermaid marks the third Disney project Awkwafina has been a part of in the last couple of years, starring in Marvel Studios' Shang-Chi and the Legend of the Ten Rings and Disney Animation's Raya and the Last Dragon

Jacob Tremblay - Flounder

Of course, no Little Mermaid project would be complete without Ariel's scaly best friend, Flounder. This time around, Flounder is played by 16-year-old Jacob Tremblay. Tremblay's frantic fish is a bit of a worrywart, who frequently partakes in Ariel's adventures, despite his cowardly nature. 

Still being a teenager, Tremblay has quite the resume. The Canadian actor appeared alongside Brie Larson in her Oscar-winning performance in the 2015 drama Room, as well as starring roles in Wonder, Good Boys, and Pixar's Luca

Noma Dumezweni - Queen Selina

McCarthy's tentacle-clad antagonist has been heralded as one of the best characters in the live-action remake, as she "helps" merfolk by granting their wishes, leaving them withering as polyps in her sea cave garden. She is the one responsible for stealing Ariel's voice and leaving the film's protagonist wishing she hadn't wished to be "part of your world."
