‘Long Long Night’ review: Heartfelt South Korean animation conveys a hard-hitting yet hopeful environmental message

Dir: Youm Kyu-bock. South Korea. 2026. 99mins

A lone White Boulder Rhinoceros raised by a herd of elephants in Africa finds a surprising kindship with a solitary penguin in Youm Kyu-bock’s hard-hitting animation; a sadly realistic but somehow still hopeful story about resilience, friendship and unconditional acceptance. More in line with Gints Zilbalodis’s occasionally harrowing Oscar winner Flow than the likes of Madagascar, this quasi-picaresque ramble delicately balances a sense of wonder and awe at the world with deeply felt loss, as both rhino and penguin reckon with tragedy that’s only alleviated by the presence the other.

An all-ages environmental paean that doesn’t rely on snarky pop culture references 

With his debut feature, which has a homeground bow in Busan competition following a Toronto premiere, author/filmmaker Youm has managed to forge an all-ages environmental paean that doesn’t rely on snarky pop culture references to keep its audience engaged, instead opting for the universal emotions of hope, sorrow and indeed, joy. And while GoogGoog Studio founder Youm and his animation lead Park Chung-shik may not carry the weight of the Pixar brand, Long Long Night easily rivals the work of its better-known peers for the accessibility of its storytelling — the film is based on Ru Ri’s Munhakdongne Children’s Literature Award winning short story — and its recognisable emotion.

As an animated film that could be easily dubbed, it could just as easily find the same niche audience films such as Flow, Travis Knight’s Kubo and the Two Strings and Michael Dudok de Wit’s The Red Turtle did for creative distributors. The visuals demand a big screen, but the film could also find a welcoming home with streamers in the future.

In addition to sorrow and joy, Youm’s vividly animated saga is also about genocide, poaching, the thorny legitimacy of zoos as we know them and our impact on the environment. It all starts with an elderly white boulder rhino, Norden (voiced by Park Ki-wook), lounging on an African grassland somewhere (the film is not concerned with precise geography) who, explains the film’s narrator (Miss A pop star Suzy), is so old he can’t remember his beginnings. The narrator does, however, and Long Long Night dives into Norden’s origins with a herd of elephants in a sanctuary.

After growing into adulthood and finding a mate with whom he has a child, Norden’s life spins out of control and into one misery after another: his family is murdered for their horns; he gets tossed into a zoo as the last of his kind; loses fellow rhino and sole friend, Angavu (So Jung-hwan); and finally escapes the zoo when civil war breaks out and all the animals are left to their own devices. He sets out across the wilderness with a penguin, Chiku (Um Sang-hyun), who is trying to get to his natural habitat at the ocean. Chiku is also alone and, having survived his partner, is the lone caregiver for an unhatched egg they were nurturing. When it hatches, precocious little penguin (Kim Gyu-na) bonds with Norden and grows up to be the story’s narrator.

Despite piling trauma upon trauma, Youm somehow keeps Long Long Night from tipping over into misery porn and creating something too grim for young children – this remains firmly family fare. Much of that is due to the lush, enveloping 3D animation, whose visuals trade in the kind of detail that really makes the film – and Norden’s life story – memorable, almost tactile: water drops, Norden’s wrinkles and eyelashes, jiggly penguin fat, patchy jackals, warm golden hour light and desert dunes effortlessly conjure the fragile landscape. Most crucially, Long Long Night is almost photorealistic (though at times it does have that suddenly omnipresent, too slick AI-ish finish) but never sacrifices emotional expression.

Youm flirts with the elegiac in some sequences that quite heartbreakingly demonstrate the damage wrought on the natural environment and the life teeming inside. Yet there is a strong sense that life will go on, even as we eliminate species at an alarming rate, and healing can be found in the unlikeliest of places. Long Long Night would come across as an ecological screed were it not for some kid-friendly levity from Chiku’s partner Wimbo, a few amusing tantrums by the narrator (never named) and a tone of genuine kindness. Instead it’s a quiet plea for us all to do better.
