South Korea’s latest science‑fiction disaster film, “The Great Flood,” premiered in domestic theaters on October 3, 2024, and was screened at the Busan International Film Festival earlier that month. The production, directed by Lee Seung‑ho and produced by K‑Film Production, stars acclaimed actress Kim Da‑mi in the lead role alongside co‑star Kwon Eun‑seong. Despite the high expectations surrounding the project, the film has generated a range of reviews, with critics acknowledging Kim Da‑mi’s strong performance while noting that the overall execution falls short of its ambitious premise.

Background and Production

Lee Seung‑ho, known for his work in the 2019 thriller “Midnight Echo,” returned to the director’s chair with a script that blends environmental disaster with speculative technology. The screenplay, written by Park Ji‑hoon, was completed in 2023 after a series of workshops that focused on realistic depictions of flooding scenarios. Production spanned eight months, with principal photography taking place in Seoul, Jeju Island, and a specially constructed set in Paju that replicated an urban landscape submerged under rising waters.

Special visual effects were handled by VFX Studio Horizon, a company that has previously contributed to the visual sequences in the Korean blockbuster “Space Rescue.” According to the production team, the film’s water effects were achieved through a combination of CGI and practical water rigs, with a budget reported at approximately 18 billion Korean won. The team emphasized that the technical team’s goal was to create a sense of immediacy and plausibility, although the final product has been described by some reviewers as uneven in its visual consistency.

Plot Synopsis

“The Great Flood” follows the story of Ji‑woo, a 28‑year‑old environmental scientist portrayed by Kim Da‑mi, who discovers an anomaly in the ocean’s salinity levels that predicts an unprecedented flood event. As the climate crisis accelerates, Ji‑woo collaborates with a group of scientists and engineers to develop a containment strategy that could prevent catastrophic loss of life. The narrative centers on the moral and logistical dilemmas faced by the team as they race against time, all while confronting the personal toll of the looming disaster.

The film balances high‑stakes action sequences with intimate character moments, illustrating the strain that the impending flood places on both public infrastructure and individual relationships. The story culminates in a climactic attempt to deploy a global sea‑level control system, which ultimately fails, leaving the audience to contemplate the limits of human intervention in the face of nature’s power.

Cast and Performances

Kim Da‑mi assumes the role of Ji‑woo, a scientist whose dedication to her research is matched only by her concern for the safety of her family. The review in the Korean Film Review praised Da‑mi’s nuanced portrayal, noting that her ability to convey both professional resolve and vulnerability anchors the film’s emotional core. Kwon Eun‑seong plays the role of Park Soo‑hyun, a seasoned engineer who provides pragmatic support to Ji‑woo’s plans. Supporting actors include Lee Jae‑woo as the skeptical government official and Park Min‑ji as Ji‑woo’s sister, whose personal storyline intersects with the main plot by providing an on‑the‑ground perspective of the flood’s impact on ordinary citizens.

Release and Distribution

“The Great Flood” was distributed by CJ Entertainment, which handled its nationwide theatrical release. The film opened on approximately 600 screens across South Korea, reaching audiences in major cities such as Seoul, Busan, and Daegu. In addition to its domestic theatrical run, the film was made available on the streaming platform Watcha within two weeks of its release, allowing international viewers to access the film with subtitles in multiple languages.

Critical Reception

Upon its release, the film received a mix of positive and negative reviews. Critics praised the film’s ambitious attempt to tackle climate change through a disaster‑drama lens, as well as the strong performances delivered by the lead actors. However, many reviewers pointed out pacing issues, noting that the narrative’s transition from scientific exposition to action sequences felt uneven. The visual effects, while generally impressive, were described by some as inconsistent, with certain scenes lacking the seamless integration that would have elevated the film’s realism.

In a detailed review published on October 12, the Korean Film Review summarized that “Kim Da‑mi’s strong performance cannot fully save this sci‑fi disaster thriller.” The review highlighted that the film’s core message about environmental responsibility remains relevant, but its execution, from script development to post‑production, detracted from the overall impact. Other outlets echoed similar sentiments, emphasizing that the film’s potential was undermined by a lack of coherent storytelling and technical polish.

Box Office Performance

According to the Korean Film Council, “The Great Flood” earned approximately 4.2 billion Korean won during its first month of release. While the figure places it behind the top three domestic releases of the same period, the film’s earnings reflect a moderate audience turnout. Analysts suggest that the mixed critical reception and the film’s niche genre may have contributed to its box office performance. The film’s streaming viewership data, however, indicates a growing international audience, with Watcha reporting over 1 million streams within the first two weeks of availability.

Implications and Future Prospects

As the global conversation around climate change intensifies, “The Great Flood” is part of a broader wave of media that seeks to raise awareness through compelling storytelling. While the film’s execution was found wanting by some reviewers, its thematic focus on environmental crisis may resonate with audiences worldwide. The production company has expressed interest in developing a series that expands on the film’s narrative universe, potentially offering a platform to explore the aftermath of the flood in greater depth.

In the coming months, “The Great Flood” will continue to be available on streaming services and may be considered for international film festivals that focus on environmental and science‑fiction themes. The film’s performance and reception could influence the trajectory of future South Korean disaster thrillers, prompting producers to reassess the balance between technical ambition and narrative cohesion.
