Unless you’ve been living under the sea, chances are you’ve heard about Disney’s live-action remake of The Little Mermaid that’s now in theaters.

Halle Bailey stars as Ariel, the young mermaid who yearns to experience life out of the water, in an updated version of the classic 1989 animated film. Melissa McCarthy takes on the role of the devious Ursula, a sea monster who offers Ariel the chance to experience life as a human—for a price.

Even before reaching the big screen, the film has seemingly divided fans at every turn—from its casting choices to the potentially off-putting CGI, and even minor lyrical changes in popular songs from the original. However, this weekend will be the first true indicator of whether the film succeeds or, well, flounders.

Either way, it won’t be for lack of star power. Here’s your guide to the cast of actors appearing in, or lending their voices to, The Little Mermaid and where you might have seen them before.

Halle Bailey

Halle Bailey, 23, plays titular mermaid Ariel, the daughter of Atlantica leader King Triton who dreams about being part of the human world. Bailey is one half of the singing duo Chloe x Halle with her sister, Chloe Bailey. As an actor, her most notable role to date has been as Sky Forster on the TV series Grown-ish from 2018 to 2022.

Disney’s casting of Bailey, first announced in 2019, has drawn racist backlash from some fans of the animated original who complained that a Black actor should not portray Ariel, who was a white character in the earlier film. #NotMyAriel even trended on social media. However, Bailey has said she moved past the negative reactions with the help of her family and is proud to play a character she resonated with as a child. “I want the little girl in me and the little girls just like me who are watching to know that they’re special, and that they should be a princess in every single way,” she told Variety.

Actor Jodi Benson, who voiced Ariel in the animated original, has stated she is proud of Bailey and specifically highlighted “her pure spirit [and] her joy” among the reasons Bailey is fit for the part. Benson, 61, makes a cameo appearance as a market vendor in the 2023 film.

Melissa McCarthy plays Ursula, an octopus-like sea witch who offers Ariel the chance to become human with treacherous ulterior motives. The comedian and actor, 52, first gained fame through TV roles as Sookie St. James on Gilmore Girls and title character Molly Flynn on the sitcom Mike & Molly, for which she won a Primetime Emmy Award in 2011. McCarthy has also starred in films such as Bridesmaids (2011), The Heat (2013), Ghostbusters (2016), The Happytime Murders (2018), and Thunder Force (2021).

The animated version of Ursula was inspired by drag queen and actor Divine, and McCarthy told Deadline her performance similarly pays homage. “I just hope to do like every incredible drag queen proud, and Divine proud,” she said. “I wanted to give her everything that, you know, she was due.”

Jessica Alexander from the Netflix series Get Even plays Ursula’s human alter ego on land.

Spanish actor Javier Bardem, 54, plays King Triton, the leader of Atlantica and Ariel’s overprotective father. The actor is best known for his role as assassin Anton Chigurh, the primary antagonist of the 2007 Western No Country for Old Men, which earned him an Academy Award for Best Supporting Actor.

The latter earned him his fourth Academy Award nomination.

During a recent appearance on the Conan O’Brien Needs a Friend podcast, Bardem discussed the intricate stuntwork required to make The Little Mermaid and praised the film’s special effects. “The only thing you can do, you have to do, is to try to learn the lines, say the lines, and forget about the whole noise around you,” Bardem said. “It’s so beautifully done, it’s so realistically done, and at the same time, has so much magic, that I’m not put off by [the CGI]. I go, ‘Wow, I believe that they are under the water.’ It’s something else.”
