Bong Joon-ho directed which 2019 South Korean black comedy thriller, the first foreign-language film to win the Academy Award for Best Picture, depicting a poor family's infiltration of a wealthy household?

The acclaimed 2019 South Korean black comedy thriller you're thinking of is "Parasite (Review)," directed by the visionary Bong Joon-ho. This gripping film masterfully tells the story of the impoverished Kim family, who ingeniously orchestrate a plan to gradually infiltrate the household of the wealthy Park family, posing as unrelated, highly qualified domestic staff. What begins as a clever scheme unfolds into a darkly humorous and ultimately tragic exploration of class dynamics.

"Parasite" made cinematic history at the 92nd Academy Awards, becoming the first non-English-language film to ever win the coveted Best Picture Oscar. Its groundbreaking success didn't stop there; the film also earned Academy Awards for Best Director, Best Original Screenplay, and Best International Feature Film. This triumph followed its earlier win of the prestigious Palme d'Or at the Cannes Film Festival, marking it as a rare film to achieve both honors.

Beyond its accolades, "Parasite" resonates deeply due to its sharp commentary on societal issues. The film is a powerful and unsettling examination of class conflict and wealth disparity, highlighting the stark differences and tensions between the rich and the poor in contemporary society. Director Bong Joon-ho himself noted the double meaning of the title, suggesting that both families, in their own ways, could be considered "parasites" within the social structure, depending on one's perspective.
