Already the team have found their Ariel in actress and singer Halle Bailey who, quite frankly, is the perfect choice - that woman has the voice of an angel, as one half of singing sisters Chloe x Halle.
And while no other official casting decisions have been announced, fans already have an idea of who they'd like to take the role of Ariel's father, King Triton - that man is Idris Elba.
The idea was originally put forward by artist BossLogic, who cooked up a poster of what the Luther star would look like as the undersea king.
We're all for it, as are the fans, who took to Twitter to express their excitement of Elba picking up the role.
"The right man for the right job," exclaimed one fan, while another wrote, "Idris Elba could record himself knitting a sweater in silence for 2 hours and I'd watch it."
A few other ideas were thrown around too, including numerous votes for The Rock, as well as one diehard Terry Crews fan who even launched a petition to get the comedian cast as Tritan.
Looks like Crews is already once step ahead, as he shared a photoshopped image of himself as the character in front of the underwater castle, alongside the caption: "Ariel's Dad!!! #ArielsGotTerry #AmericasGotTerry."
In addition to the fan art, BossLogic also put together a mock poster of how Halle might look in the role, placing her in the classic 'Ariel on a rock as a wave splashes behind her' pose (you know the one) with red dreads. And yes, she looks rad.
If you haven't been following Halle's career so far, along with her sister Chloe, she is a self-made musician and singer, having moved to Atlanta to LA with her family to live out her dream.
"We knew that being out here was definitely better for the music scene," she told Time magazine.
In the same interview, her sister Chloe said: "From 10 and eight we just wrote our own songs, and that's how we learned."
From there, the pair were picked up by music industry titan Beyonce and signed on to her label Parkwood Entertainment.
This isn't Halle's first brush with Disney, as the duo's song 'Warrior' was featured on the soundtrack for Ava DuVernay's 2018 flick A Wrinkle in Time
And this isn't her first time at the rodeo when it comes to acting either, as she stars alongside her sister in Black-ish spin-off Grown-ish.
Her casting in the live-action Little Mermaid remake will only go to boost her career further and we're all for it.
As for Elba, we'll have to wait and see if he's booked to play her on-screen pops (or if Crews is the one who takes the trident).Featured Image Credit: @BossLogic
