The film was in part inspired by an incident in 2000 in which a Korean mortician working for the U.S. military in
Seoul dumped a large amount of
formaldehyde down the drain. In addition to its environmental concerns, this has added some antagonism against the United States.
[8] The American military situated in South Korea is portrayed as uncaring about the effects their activities have on the locals. The chemical agent used by the American military to combat the monster in the end, named "Agent Yellow" in a thinly-veiled reference to
Agent Orange, was also used to satirical effect.
[4] The director, Bong Joon-ho, commented on the issue: "It's a stretch to simplify
The Host as an anti-American film, but there is certainly a metaphor and political commentary about the U.S."
[9] Because of its themes that can be seen as critical of the United States, the film was lauded by
North Korean authorities,
[10] a rarity for a South Korean blockbuster film.
The film features a satiric portrayal of the South Korean government which is portrayed as bureaucratic, inept, and essentially uncaring. Korean youth protesters are featured satirically in the film, with a mixed portrayal, partially heroic, and partially self-righteous and oblivious. According to Bong Joon-ho, the Park Nam-il character is a deliberate anachronism, a reference to South Korea's troubled political history, which involved violent protest. "When you look in terms of this character, it's sort of like the feeling of time going backwards. [...] You could say that he is the image of the college protester back ten years ago; it doesn't exist in the present day."
