Parasite

The script is based on a play Bong wrote in 2013. He later adapted it into a 15-page film draft, which was split into three different drafts by Han. Bong said he was inspired by the Korean film The Housemaid (1960) and the 1930s Christine and Léa Papin incident. Filming ran from May to September 2018 and included cinematographer Hong Kyung-pyo, editor Yang Jin-mo, and composer Jung Jae-il. Parasite premiered on 21 May 2019 at the Cannes Film Festival, where it became the first Korean film to win the Palme d'Or. It was praised for its direction, screenplay, performances, editing, and production design. It was released in South Korea by CJ Entertainment on 30 May, grossing $258 million worldwide on an $11.4 million budget.

Among its numerous accolades, Parasite won the Academy Award for Best Picture at the 92nd Academy Awards, becoming the first non-English-language film to do so. It won an additional three Oscars, for Best Director, Best Original Screenplay, and Best International Feature Film. It is the first South Korean film to receive any Academy Award recognition, and one of only four films overall to win both the Palme d'Or and the Academy Award for Best Picture, the first such achievement in over 60 years. It won the Golden Globe Award for Best Motion Picture – Non-English Language and the BAFTA Award for Best Film Not in the English Language, and became the first non-English-language film to win the Actor Award for Outstanding Performance by a Cast in a Motion Picture.

Since its release, Parasite has been regarded as Bong's magnum opus and was ranked in the 2022 Sight and Sound poll as the 90th best film of all time. In 2025, The New York Times ranked it as the best movie of the 21st century so far in a list based on a vote by readers, actors, and directors. As of February 2025, an HBO limited television series based on the film is in early development.
