Already, the Korean movies releasing in December 2025 is raising massive excitement, and this final month of the year is promising with some of the biggest releases in store, spearheaded by several of the most popular names in the industry. This time, December feels a little different, with Hong Kyung continuing his incredible year after charming audiences with his heartfelt voice acting in Lost in Starlight and showing off his playful, comedic side in Good News. Joining in to add more anticipation is Mun Ka-young, who has been reigning on the small screen in recent years but is finally returning to the big screen for the first time since 2016.
It gets even more exciting with The Great Flood, which finally makes its release on Netflix after so many postponements and rescheduling, setting off waves of anticipation among global audiences. Along with that, audiences will also get to see powerful adaptations of stories that have captured hearts across the world. With this mix of highly-awaited comebacks, international releases, and favourite remakes, December 2025 already looks like a memorable month for Korean cinema.
All Korean Movies Releasing in December 2025
Concrete Market (콘크리트 마켓)
Concrete Market, coming December 3, 2025, materialises the post-apocalyptic Korea of Hong Gi-won, while Hong Kyung, Lee Jae-in, Jeong Man-sik, and Yoo Soo-bin make up the ensemble cast. That sets a story which happens after a catastrophic earthquake, inside the only remaining apartment building, in which a disorganised bartering hub called “Hwanggung Market” comes into being.
In such a situation, when Tae-jin works under the frightening Park Sang-yong, a power shift starts to happen. Mysterious Hee-ro tempts him with the question of whether he wants to control the market himself. In that respect, along with the merciless right-hand man Park Cheol-min, the movie turns this isolated apartment into a heated battlefield for survival. And the thriller cements its place as one of the strongest additions to Korean Movie releases in December 2025.
The People Upstairs (윗집 사람들)
Also releasing on December 3, 2025, The People Upstairs marks the comeback of Ha Jung-woo both as a director and a lead actor. Adapted from Cesc Gay’s earlier film and play, this Korean adaptation deals with two couples whose lives get intertwined because of a complaint about noise coming from the other couple’s apartment. Gong Hyo-jin and Kim Dong-wook act as Jeong-ah and Hyun-soo, the quiet downstairs couple, while Ha Jung-woo and Lee Hanee play the lively upstairs couple, Mr Kim and Soo-kyung. What was supposed to be a night for dinner to resolve tension unravels into secrets, confessions, and unexpected humour, making it one of the most relatable and refreshing titles in December 2025 Korean movies.
Even if This Love Disappears from the World Tonight (오늘 밤, 세계에서 이 사랑이 사라진다 해도)
From director Kim Hye-young, this heartbreaking adaptation of the novel of the same name by Ichijo Misaki hits theatres on December 24, 2025. The movie follows the story of Kim Jae-won, played by Choo Young-woo, a high school boy with hereditary heart failure who has lived his life without much hope. One day, his life intertwines with that of Han Seo-yun, played by Shin Shi-ah, an anterograde amnesia girl whose memories reset every time she wakes up.
The romance between the two gradually develops into a fragile yet beautiful journey, with moments often so fleeting and realities touching the heart. This will be one of the most emotionally profound K-movies to be released this December 2025, a Korean remake of the successful Japanese film adaptation released in 2022.

The Great Flood (대홍수)
Netflix’s The Great Flood finally hits screens worldwide on December 19, 2025, after multiple delays. Helmed by Kim Byung-woo, the film drops viewers into a dystopian world engulfed by water. Kim Da-mi plays An-na, an AI researcher stuck inside a high-rise apartment as the floodwaters rise in their relentless march, while Park Hae-soo stars as Hee-jo, for some reason, a human resources security agent dead set on saving her. As the structure goes under and the minutes tick by, hidden motives and emotional stakes are revealed. Having premiered at the Busan International Film Festival, this long-awaited title anchors the global side of Korean movie releases in December 2025.
Choir of God (신의악단)
Written by Kim Hwang-sung and directed by Kim Hyeong-hyeop, Choir of God stars Park Si-hoo as Park Gyo-sun and Jung Jin-woon as Captain Kim, closing the year on December 31, 2025. Situated in North Korea, the film traces a government attempt to circumvent international sanctions by collaborating with a Hungarian NGO in constructing churches in Pyongyang.
What starts as a strategic move spirals into chaos when the so-called “Victory Orchestra” formed for a revival meeting turns out to be a secret group of underground believers. As their hymns reveal their true identities, the narrative blends moments of tension, humour, and heartfelt conviction in one unique close to the Korean movies lineup for December 2025.
Once We Were Us (만약에 우리)
Alongside Koo Kyo-hwan, Once We Were Us will mark Mun Ka-young’s highly anticipated big-screen comeback, under the direction of Kim Do-young, releasing on December 31, 2025. A Korean remake of the Chinese hit Us, and Them tells the story of two young souls in 2008: Eun-ho and Jeong-won coincidentally meet each other on a bus heading home.
As they navigate the challenges of Seoul’s fast-lane life together, a friendship blossoms from shared dreams and unspoken affection. Life rips them apart, only to let fate throw them together once more over a decade later on a flight back to Korea. Forcing themselves to reopen the trunk of memories and emotions they had laid to rest, this film is about nostalgia and highly evocative finales.
