Arco review: If you love animation, you need to see this gorgeous climate change fable
I fell in love with Arco from its very first frames.
In these opening moments, a flock of birds soars towards a cluster of towers jutting into the clouds, each holding up platforms covered in greenery and wind turbines. The image is utopian, yet there’s a slightly foreboding to it. What led humanity to move to the sky? What lies below the clouds? The answer, unsurprisingly, is ecological disaster of our own making.
That tension between beauty and hard truths fuels the entirety of Arco, as French director Ugo Bienvenu pairs a charming tale of friendship with a sobering look at the realities of climate change. It’s a glorious sci-fi journey, one told through the most remarkable animation you’ll see this year.
What’s Arco about?
The people who live on the platforms from Arco‘s opening scene are able to time travel. They fly to the past with the help of colorful cloaks and light-refracting crystals, bringing rainstorms and rainbows as they go.
Kids under the age of 12 are not allowed to use this technology, which doesn’t sit right with 10-year-old Arco (voiced by Juliano Valdi in the English-language dub). So what does this aspiring adventurer do? He steals his sister’s cloak and jets off to 2075, only to find himself stuck there. Thankfully, he has a newfound friend in Iris (voiced by Romy Fay), who is determined to help him get back to his own time.
Arco is another formidable animated film about climate change.

While Arco’s future is an idyllic one, fueled by renewable energy and a deep connection to nature, Iris’ version is far more troubling — and hits closer to home.
Iris lives in a suburb that would seem right at home in our current moment, apart from a few changes. Her robot caretaker Mikki (voiced by Natalie Portman and Mark Ruffalo), as well as her town’s hordes of robot laborers, speaks to significant technological advancements. So, too, do the holograms her workaholic parents (also voiced by Portman and Ruffalo) use to communicate while they’re away at work.
But the most telling difference between our present and Iris’ future is that of the protective bubbles that pop up around people’s houses during ever-frequent destructive weather events. The threat of severe storms looms over the town, while kids talk casually about their families preparing for disaster in the face of encroaching wildfires. Clearly, this is a society that lives with the impacts of climate change, yet makes no large-scale attempts to mitigate its effects for future generations. (Sound familiar?)
Arco knows that climate change — and humans’ acceleration of it — is what led his ancestors to make their way above the clouds. Through his eyes, everyday elements of Iris’ world become accelerants of oncoming ecological collapse, such as the town’s cars, or the excess of grocery stores, as opposed to his family’s homegrown approach.
Bienvenu is never too heavy-handed in his messaging around climate change. Still, each of these world-building details combine to build a growing background sense of dread, one that only makes Iris and Arco’s friendship all the sweeter by comparison. They offer up hope in a rapidly deteriorating world.
Arco‘s treatment of climate change recalls two of 2024’s most outstanding films, Flow and The Wild Robot. Like Arco, each present worlds impacted by ecological calamities. However, these are not grand, sweeping stories of saving the world, but rather stories of the innocents — like Flow and The Wild Robot‘s animals, or Arco‘s young Iris and Arco — who have no choice but to endure these storms. In addition to Flow and The Wild Robot, Arco is further proof of animation’s ability to communicate the realities of climate change to younger and older audiences alike.
Arco is a downright stunner.
And what animation is on display in Arco! A comic book artist himself, Bienvenu translates his 2D illustrative style to the big screen. The effect is glorious, reminiscent of the fantastical works of Jean Giraud (aka Mœbius) and the films of Studio Ghibli.
In addition to the rainbows and solarpunk sky towers of Arco’s future, Bienvenu finds wonder in the 2075 timeline. The forests of Iris’ town are lush wonderlands, while her school provides unexpected opportunities for escapism. Each classroom can transform into a variety of environments, from galaxies to underwater landscapes, offering Bienvenu and his team opportunities to flex their animation muscles and take Iris and Arco’s adventure to new heights.
Another highlight of the animation is the mysterious trio of men (voiced by Will Ferrell, Andy Samberg, and Flea) who are tracking Arco down. They each rock colorful suits, bowl cuts, and rainbow glasses, and their bumbling attempts to find Arco are among the funniest and most visually distinct moments of the film.
In a mainstream animation landscape dominated by 3D-animated films, Arco‘s visuals are a testament to the enduring power of 2D work, as well as French filmmakers’ commitment to the medium. If you love animation, run, don’t walk — or better yet, fly by rainbow — to catch it.
