The live-action remake of The Little Mermaid has made some changes from the original animated movie, including the removal of the polyps transformation scenes. Director Rob Marshall explained that the decision was made because the transformation wouldn't have worked well in a live-action film. Marshall felt that having plants turn into people felt like an animation concept and that the scene could come across as comical. Instead, the remake focuses on reintroducing the undersea world with its talking fish, magic, and beautiful locations, and gives King Triton a more dignified conclusion. In the remake's climax, Triton is turned to dust, but there are no scenes of humans turning into polyps or vice versa.
It's a common belief that certain elements that work well in animation may not translate well to live-action. The concern arises when these elements cross the line and become too absurd to be taken seriously. This was the worry with this particular project, as it seemed to be pushing the boundaries of believability.
How The Live-Action Little Mermaid Differs From The Original
The Little Mermaid introduces significant changes to the classic film, including the revelation that Ursula, the villain, is the banished sister of King Triton and seeks both vengeance and her brother's crown. By offering new motivations, this change makes Ursula a more comprehensible and three-dimensional character. The live-action adaptation also features new songs from Lin-Manuel Miranda and a more active role for Ariel in the fight against Ursula, which helps to keep her in the spotlight of her own movie. These changes work together to create a greater whole and distinguish it from the original without diminishing its legacy.
