The 2023 live-action adaptation of The Little Mermaid generated so much buzz that it's only natural there is speculation about a sequel, but if it ends up coming to fruition, the movie can't remake the animated follow-up. Although it received mixed results at the box office, the 2023 Little Mermaid is still considered to be one of Disney's best live-action remakes, and it saw much success when released on streaming. After Halle Bailey proved she had the singing and acting skills to be the perfect Ariel, it makes sense for her to have another opportunity to shine and for her portrayal to be explored further.
