## **The Great Flood Release Date — A Three-Year Journey**

The Great Flood release date was confirmed as December 19, 2025, with the release of the official teaser trailer. [Wikipedia](https://en.wikipedia.org/wiki/Girl_from_Nowhere:_The_Reset) Filming began on July 1, 2022, and lasted for several months, concluding on January 5, 2023 — meaning the film was released just shy of three years after filming concluded.

That’s an unusually long post-production timeline, which has only added to the anticipation surrounding this movie. The scale of the disaster sequences and the complexity of the production clearly demanded extraordinary care, and based on the trailer, every moment of that wait was worth it.

## **What Is The Great Flood About?**

A great flood has hit planet Earth. People, including An Na and Hee Jo, struggle to survive in their apartment building, which is sinking into the water. An Na is an AI development researcher and Hee Jo belongs to a human resource security team, who is trying to save An Na from the disaster. But why is Hee Jo trying to save An Na and who is behind it?

The premise does something smart — it takes the visceral spectacle of a classic disaster movie and layers it with a genuine mystery. Why specifically is An Na being targeted for rescue? What is the connection between her AI research and whoever is pulling the strings? The intersection of apocalyptic survival thriller and corporate conspiracy makes The Great Flood far more compelling than your average disaster film.

## **The Star-Studded Cast**

Kim Da Mi has been cast in the role of An Na. The South Korean actress has already starred in lead roles in two extremely popular K-Dramas on Netflix — Our Beloved Summer and Itaewon Class. [Wikipedia](https://en.wikipedia.org/wiki/Girl_from_Nowhere:_The_Reset)

Park Hae Soo is one of the most instantly recognizable faces on Netflix thanks to his role as Cho Sang Woo or “No. 218” in Squid Game, and as Berlin in the Korean adaptation of Money Heist. [Wikipedia](https://en.wikipedia.org/wiki/Girl_from_Nowhere:_The_Reset)

Together, they form one of the most exciting Korean film pairings of 2025 — a global Netflix star meets a critically acclaimed leading actress, inside a flooded apartment building with the entire world collapsing around them.
