Parasite

Bong Joon-ho's four-time Oscar winner follows a poor family infiltrating a wealthy household, using architecture as visual metaphor for class divide. Production designer Lee Ha-jun built the Park mansion as a specially constructed set — the ground floor and garden on an outdoor lot, the basement on a soundstage — while the semi-basement neighborhood was built inside a water tank for the devastating flood sequence. Hong Kyung-pyo's cinematography uses sunlight itself to distinguish rich from poor, with warm natural light flooding the mansion while only a sliver reaches the basement.
