Most people remember the 2003 live-action Peter Pan for Jeremy Sumpter’s effortless charm or that incredible flying sequence over London. It was a lush, big-budget romantic epic that felt way more grounded than the Disney cartoon we all grew up with. But honestly? If you ask anyone who watched it as a kid what stayed with them, they won’t talk about the sword fights or the Darling nursery. They’ll talk about the mermaids. Specifically, how terrifyingly "off" they felt.
The 2003 Peter Pan mermaids weren't just background set dressing. They were a total departure from the shell-bra-wearing, giggling sirens we were used to seeing. Director P.J. Hogan decided to lean into the darker, more predatory roots of J.M. Barrie’s original text. It worked. Maybe it worked a little too well.
The uncanny valley of the Black Lagoon
There is a specific shot in the movie where Wendy leans over the edge of the Jolly Roger or peers into the depths of the lagoon, and these creatures just... drift. They don't look like humans with fish tails. They look like prehistoric predators that happen to have human faces.
Hogan used a mix of practical effects and early 2000s CGI that, surprisingly, holds up because it embraces the "uncanny valley." Their skin has this translucent, almost gelatinous sheen to it. When they hiss, you see rows of sharp, needle-like teeth. It’s a far cry from Ariel. These are creatures that would genuinely drown you for fun, which is exactly how Barrie described them in the book. He wrote that they were "wild and suspicious" and that their laughter was "hateful."
The 2003 film is one of the few adaptations to actually capture that malice. You’ve got these pale, wide-eyed girls with webbed fingers and cold, calculating expressions. They don't want to be Wendy's friend. They want to pull her under.
Why the CGI actually works today
Usually, CGI from 2003 looks like a PlayStation 2 cutscene. But because the 2003 Peter Pan mermaids were designed to look alien and wet, the digital sheen actually enhances the effect. Water is hard to animate. However, the team at Industrial Light & Magic (ILM) leaned into the distorted nature of underwater light.
By layering the digital tails over the actors' movements, they created a swimming style that feels heavy and powerful. It’s not graceful like a ballet; it’s efficient like a shark. When you watch them dart through the lagoon, there’s a sense of physical weight that most modern superhero movies lack.

The sound design helps too. They don't speak English. They make these guttural, clicking noises and high-pitched screeches. It strips away the humanity. It reminds the audience—and Wendy—that Neverland is a dangerous place where the rules of the nursery don't apply.
P.J. Hogan’s darker vision for Neverland
The director didn't want a candy-coated world. He wanted a world that felt like a child's dream—and dreams are often jagged around the edges. Hogan famously pushed for the mermaids to be "frighteningly beautiful."
One of the most memorable moments is when Peter interacts with them. He’s the only one they respect, yet even with him, there’s a tension. He treats them like dangerous pets. For Wendy, they represent the jealousy and the raw, untamed nature of adulthood and sexuality that she isn't ready for. The movie uses the mermaids to highlight Wendy’s insecurity. When they look at her, they aren't curious; they're judgmental.
Interestingly, the actresses chosen for these roles weren't just extras. They had to undergo intense makeup sessions to get that "drowned" look. The pale palette—pinks, greens, and ghostly whites—was a deliberate choice to contrast with the vibrant jungle of the island. It makes the lagoon feel like a graveyard.
The "Wendy vs. The Mermaids" scene
Think back to the scene where Wendy tries to get information. One of the mermaids pops up, looking almost ethereal, before suddenly baring those teeth and lunging. It’s a jump scare that actually earns its place. It shifts the tone of the movie from a fantasy adventure to a survival horror for a brief second.
This scene is pivotal because it breaks the illusion of Neverland as a safe haven. If the mermaids—who are supposed to be the most beautiful things in the world—are this vicious, then Captain Hook is the least of Wendy's worries. It reinforces the idea that Peter lives in a world of monsters.

Comparing 2003 to other versions
If you look at the 1953 Disney version, the mermaids are basically mean girls in a pool. They splash Wendy and giggle. In the 1991 movie Hook, they are briefly seen as shimmering, helpful beings that save Peter from drowning. They’re mystical and kind.
But the 2003 Peter Pan mermaids represent a return to the Edwardian Gothic roots of the story. They represent the "dark" side of the moon. This version of the film remains the most faithful to the spirit of the book’s danger. In the novel, the mermaids are so dangerous that the lost boys stay away from the lagoon at night. The 2003 film is the only one that makes you understand why.
- Disney (1953): Jealous, bratty, human-like.
- Hook (1991): Ethereal, helpful, glowing.
- Pan (2015): Over-the-top CGI, less personality, very "fantasy-heavy."
- Peter Pan (2003): Predatory, uncanny, teeth-forward, loyal to the book.
The practical makeup used in 2003 gave the skin a texture that CGI just can't replicate. It looked like fish scales blended with human pores. It was gross. It was perfect.
The legacy of the lagoon
Why do we still care about these minor characters twenty-some years later? Because they represent a time when big-budget family movies were allowed to be weird. They weren't focus-grouped into being "marketable" or "toy-friendly." No kid wanted a doll of the 2003 mermaid because they were genuinely scared of them.
That fear creates a lasting memory. It’s the same reason people remember the Gmork from The NeverEnding Story or the skeksis from The Dark Crystal. When a creator takes a risk and makes the "pretty" things scary, it sticks in the subconscious.
The 2003 Peter Pan mermaids serve as a masterclass in creature design. They prove that you don't need a massive amount of screen time to leave a mark on a generation of viewers. You just need a clear vision and a willingness to make the audience a little uncomfortable.

Watching it again through an adult lens
If you go back and watch the film today, you'll notice things you missed as a kid. You'll see how the lighting changes when they're on screen. The water goes from a bright turquoise to a murky, deep indigo. It’s a visual cue that we’ve entered a different realm.
The way they circle the ship is also haunting. They don't just swim; they stalk. It adds a layer of dread to the Jolly Roger scenes. You realize the pirates aren't just stuck on a ship—they're surrounded by things that would love to see them fall overboard.
It’s also worth noting the performances. The actresses used their eyes to convey a lack of empathy. There’s no warmth there. It’s cold-blooded. It makes Peter’s ability to communicate with them feel even more impressive and, honestly, a little bit more disturbing. It shows how far he has drifted from being a "normal" boy.
Practical takeaways for fans and creators
If you’re a filmmaker or a writer, there’s a lot to learn from how these creatures were handled.
First, don't be afraid of the uncanny. Sometimes, making something look almost human but not quite is more effective than a full-blown monster. Second, sound design is 50% of the character. The clicks and hisses did more to establish the mermaids' threat than their teeth ever could. Finally, stay true to the source material. J.M. Barrie’s mermaids were never meant to be nice. By leaning into that, Hogan created something timeless.
To revisit this specific brand of nostalgia, your best bet is to find the Blu-ray or a high-definition stream that hasn't been overly compressed. You need to see the detail in the skin and the subtle movements in the background of the lagoon scenes to really appreciate the craft.
Look for the "Making of" featurettes if you can find them. Seeing the prosthetic work and the lighting rigs used to simulate underwater environments explains why these mermaids look so much better than the ones in modern blockbusters with ten times the budget. They had a soul—even if that soul was a bit murderous.
The next time you're scrolling through streaming services, give the 2003 Peter Pan another look. Skip to the lagoon. Watch the way the water moves. It’s a reminder that sometimes, the best part of a story is the one that hides just beneath the surface, waiting to bite.
