This isn't a Disney production.
I like Miranda, but his songwriting does NOT hold a candle to what Howard Ashman did with The Little Mermaid and the rest of the Disney Renaissance films.
I'm definitely more interested in the Disney version. Let's see which version gets made first.
It seems like after hearing the pitch for the new film, Disney really wants to get this live-action Mermaid out ASAP. Alan Menken wasn't attached to the BATB remake until they cast the film, but now he's attached to this remake right as it's being developed.
This will be probably one of their "Untitled Fairy Tale" films slated for 2019: March 29, November 8, or December 20. I would say Disney is eyeing the first two, especially November. If they time it right, they ought to release it on the 20th anniversary of the animated film's release.
With all the Little Mermaid references in Wonder Woman, Disney should get moving on this film.
Apparently Lindsay Lohan wants to star in this.

She expressed interest as recently as this year. But isn't Ariel meant to be 16? Lindsay Lohan looks like she's in her 40s.
