Parasite (Korean: 기생충; RR: Gisaengchung) is a 2019 South Korean black comedy thriller film directed by Bong Joon Ho, who co-wrote the screenplay with Han Jin-won. It stars Song Kang-ho, Lee Sun-kyun, Cho Yeo-jeong, Choi Woo-shik, Park So-dam, Jang Hye-jin, Park Myung-hoon, and Lee Jung-eun. The film follows a poor family who infiltrate the home and life of a wealthy family.
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.
