Some things are better left untouched under the sea.

Chloë Grace Moretz, star of the new live-action “Little Mermaid” film, dished on preparing for her role and revealed a key detail that left the fandom in a tiff.

In an interview with Entertainment Tonight, Moretz said that her character will trade Ariel’s red locks for something a lot different.

“I want red hair! We’re going with the Hans Christian Anderson novel, so I’ll actually have blond hair,” said Moretz, adding that the remake will be a “modern revisionist tale” that will be “progressive for young women.”

As pointed out by BuzzFeed, the Anderson novel never actually mentions the hair color of the mermaid, only describing her locks as “long,” “thick” and “waving.”

Fans are already a bit upset that Disney isn’t making the film — Working Title and Universal are behind the new movie. Maybe the lack of red hair is that reason that Sofia Coppola, the initial director for the movie, dropped out for rumored creative differences.
