Twenty years after The Host was released, Bong Joon-ho has reflected on the inspirations and production challenges behind the monster movie. The film is returning to theaters on November 20, 2026, with a 4K restoration that the director says was designed to recreate the look of a high-quality 35mm print, without digitally altering the film’s content.
Bong also clarified a story he told in a 2006 interview, when he said he had spotted an unusual creature in Seoul’s Han River as a teenager. He now describes the sighting as a possible delusion shaped by the pressure of high school. Two real elements fed his imagination: he lived near the river and regularly saw it, and he was fascinated by the Loch Ness monster. He wondered what it would be like if a similar creature appeared in the Han River.
The film’s premise drew on both a real environmental incident and a fictional monster movie. Bong says the scene in which formaldehyde is dumped into a drain was inspired by the McFarland Incident in Korea in 2000, which prompted protests from environmental groups. He also cited the 1980s film Alligator, in which a baby alligator released into the sewers grows into a giant creature. Those ideas helped shape The Host’s political satire.
Although Bong enjoyed Godzilla movies when he was younger, he says they did not directly influence The Host. He wanted a more realistic creature, small enough to hide between buses rather than destroy buildings. At the time, he was more drawn to the monsters in Ridley Scott’s Alien and John Carpenter’s The Thing.
The production’s limited visual-effects budget also shaped the film’s climactic confrontation. Because the sequence was filmed on a real riverbank, the actors had to react to a monster that was not physically present. Bong recalls feeling embarrassed as passersby watched the cast perform against an empty space. He says the scene used only seven shots showing the creature in full, so he had to sustain the sense of danger when it was offscreen.
Bong says that constraint ultimately pushed him to be more creative. He is now developing several film ideas, including two that could be classified as horror, though he says his upcoming animated feature, Ally, is not a horror film. It does, however, include numerous creatures and one character he describes as a funny, monster-like figure.
