The premise brings the families into an unequal relationship within a shared space. The film’s shifts in tone are part of how that relationship develops.

The 2020 Academy wins were Best Picture, directing, original screenplay and international feature. They followed the 2019 Palme d’Or, giving the film major recognition in both festival and Academy settings.

The relationship between the two households depends on who can enter a space, what work is done there and what must remain unseen. Watch entrances, stairs and changes of level as practical features before treating them as symbols. The geography gives the suspense clear rules: a character may need to be close enough to do a job but far enough away not to be noticed.

The credited production designer is Lee Ha Jun, with cinematography by Hong Kyung Pyo and editing by Yang Jinmo. Their work lets the same domestic environment support comedy, embarrassment and danger. A useful question during a scene is what each person knows about the room and its other occupants. Differences in knowledge can change the tone even before the physical setting changes.

Criterion’s edition includes both the colour film and a black-and-white version. These are presentation choices for the same story, not evidence of a different original release year. For a first viewing, choose your subtitle or dubbing language and avoid an extended plot summary: the official premise supplies enough context. Afterwards, return to the arrangement of the households and the film’s shifts in tone rather than treating one surprise as the whole explanation.
