It happened by accident. One minute, a small, blue faun named Mune is just minding his own business in a world where the sun and moon are literally towed across the sky by giant, ancient temple-beasts. The next, he’s holding the leash of the moon. He didn't ask for it. He definitely wasn't trained for it. But that’s the chaotic, sparkling heart of Mune: The Guardian of the Moon, a French animated film that somehow feels like a fever dream directed by a celestial poet.
Most people haven't seen it. That’s the tragedy.
Released originally in 2014 (France) and 2015 (internationally), the movie struggled with a botched US release and a limited marketing budget that buried it under the weight of Pixar and DreamWorks giants. But if you actually sit down and watch it, you realize it’s one of the most inventive pieces of world-building in the last twenty years. It doesn't follow the "talking animal" trope or the "pop-culture reference every five minutes" formula. It’s pure, unadulterated mythology.
The World Where Gravity is Just a Suggestion
The premise of Mune: The Guardian of the Moon is delightfully weird. In this universe, the sun and the moon aren't giant balls of gas or rock floating in a vacuum. They are physical objects tethered to "Temples"—gargantuan walking creatures that roam the planet. The Sun Temple is a massive, stony beast that radiates heat, while the Moon Temple is a spindly, graceful creature that treads softly through the night.
Everything is balance.
Sohone, a cocky, amber-colored hero made of stone and fire, is chosen to be the Guardian of the Sun. He’s the obvious choice. He’s strong. He’s loud. He looks the part. But when the time comes to pick the Guardian of the Moon, the lunar ewe—a mystical creature that chooses the successor—bypasses the elite candidates and picks Mune.
Mune is a forest sprite. He’s spindly. He’s blue. He has ears that twitch at the slightest sound. Honestly, he’s terrified.
This sets off a chain reaction of disasters. Because Mune doesn't know what he's doing, he accidentally lets the moon go adrift. Seizing the opportunity, Necross—a fallen former Guardian who turned into a lava-dripping demon living in the underworld—sends his minions to steal the sun. It’s a classic "hero's journey" setup, but the execution is anything but standard.

Why the Animation Style Matters More Than You Think
Benoît Philippon and Alexandre Heboyan, the directors, did something gutsy here. They didn't just stick to high-end 3D CGI.
Whenever the characters enter the dream world or certain mythological sequences occur, the movie shifts styles. We see gorgeous 2D animation that looks like it was hand-painted on old parchment. It’s jarring in the best way possible. It reminds you that you're watching a fable, not just a product meant to sell lunchboxes.
The character designs themselves are a masterclass in silhouette. You’ve got Glim, a girl made of wax who melts if she gets too hot and freezes solid if she gets too cold. She’s the brains of the operation, and her physical fragility adds a layer of genuine stakes to the adventure. If she stays in the sun too long, she literally loses her shape.
Then there’s the underworld. It isn't just "scary fire place." It’s a jagged, industrial, soot-stained nightmare that contrasts sharply with the soft, glowing bioluminescence of the moon-forest. The texture work on Sohone’s skin—cracked, cooling magma—shows a level of detail that usually requires a Disney-sized budget.
The Messy Reality of the Release
Let's talk about why you might have missed this.
Mune: The Guardian of the Moon was produced by On Animation Studios. In France, it was a hit. It won the Young People's Jury Award at the TIFF Kids International Film Festival. It was nominated for Annecy. It had all the momentum in the world.
Then it came to America.

The distribution was, frankly, a mess. It didn't get a major theatrical push. It landed on Netflix and various VOD platforms years after its peak buzz. Even the voice acting had two different versions—the original French cast (which is excellent) and an English dub featuring Patton Oswalt and Christian Slater. While the English dub is solid, the translation lost some of the poetic weight of the original script.
It’s a "cult classic" in the truest sense. It lives on Tumblr art blogs and niche animation Discord servers where people obsess over the lighting engine used for the moon’s glow.
What Most People Get Wrong About Mune
There’s a common misconception that this is a "kids' movie" in the sense that it’s shallow. People see the bright colors and assume it's just fluff.
Actually, the movie deals with some pretty heavy themes:
- Imposter Syndrome: Mune spends half the movie convinced the universe made a mistake. He’s not just "learning to be a hero"; he’s dealing with the crushing weight of a responsibility he never wanted.
- Corruption of Power: The villain, Necross, isn't just evil for the sake of it. He’s what happens when a Guardian becomes obsessed with possession rather than protection.
- Interdependence: The movie hammers home that the sun cannot exist without the moon. It’s not a competition.
If you look closely at the scene where Mune enters the world of dreams to find the lost moon, it’s remarkably sophisticated. It plays with the idea that our fears are just shadows we haven't learned to tame yet. It’s a psychological depth you don't usually find in a movie where the main character has giant blue ears.
A Technical Look at the World-Building
The physics of Mune: The Guardian of the Moon are fascinating if you’re a nerd for world-building. The world doesn't rotate. The Temples are the only reason time moves. If a Temple stops walking, that part of the world is stuck in eternal day or eternal night.
Think about the ecological impact of that. The flora and fauna have evolved specifically around these walking giants. The "Leeyoons" (little glowing creatures) act as a sort of bridge between the celestial energy and the ground. It’s a holistic system.

The film uses a lot of soft lighting and "bloom" effects to sell the idea of lunar magic. It’s a deliberate stylistic choice that makes the movie feel "soft." Compare this to the sharp, high-contrast look of something like The Incredibles. Mune wants you to feel like you’re looking through a telescope at a galaxy far, far away.
How to Experience it Properly
If you're going to watch it—and you should—try to find the highest resolution possible. The 4K versions bring out the "glitter" in the moon dust that gets lost in standard definition.
Also, pay attention to the score by Bruno Coulais. He’s the same guy who did the music for Coraline and Song of the Sea. He uses these ethereal, haunting melodies that make the forest feel alive. It’s not a "soundtrack"; it’s a soundscape. It’s minimal when it needs to be and overwhelming when the Sun Temple starts its march.
Actionable Steps for Animation Fans
If the story of Mune resonates with you, don't stop there. The world of "International Feature Animation" is where the most creative risks are being taken right now.
- Watch the French version with subtitles. Even if you don't speak the language, the cadence of the original actors fits the character designs of Mune and Glim more naturally than the Americanized dub.
- Check out the "Art of Mune" books. They are rare now, but the concept art shows how much the creators leaned into surrealism before the 3D models were even built.
- Explore On Animation Studios' other work. They were also involved in The Little Prince (2015), which carries a similar emotional DNA and visual whimsey.
- Support independent distributors. GKIDS is usually the one bringing these gems to the US. If you see their logo on a movie, it’s almost guaranteed to be better than the generic CGI slop being pumped out by major studios.
Mune: The Guardian of the Moon reminds us that animation is a medium, not a genre. It’s a way to tell stories that would be impossible in live-action. It’s a story about a little blue guy who lost the moon, but it’s really about the terrifying, beautiful moment when we realize we’re responsible for the world around us.
Go find a copy. Dim the lights. Let the moon-forest take over. It’s worth the trip.
