How Sleep was received

2023 · Jason Yu · Sleep on Sightlines

The arc

Premiered in Critics' Week at Cannes 2023 and became a word-of-mouth hit at home in Korea; it's now watched with extra poignancy as one of Lee Sun-kyun's final films before his death in December 2023.

What’s debated

The ending is the whole conversation: is what's happening supernatural or psychological, and fans split hard over which reading the film actually endorses.

Its footprint

Bong Joon-ho's rave — calling it the most unique horror film and smartest debut he'd seen in a decade — became the film's calling card, stamped on posters and every review.

Where it stands

A Letterboxd-era K-horror favorite and one of the most admired genre debuts of the 2020s.

Did you know? Director Jason Yu was Bong Joon-ho's assistant director on Okja, and Bong repaid the apprenticeship by publicly declaring Sleep the smartest debut film he'd seen in ten years.

Named by the director

• Bong Joon-ho — Yu has repeatedly cited his mentorship under Bong on Okja as formative to how he directed Sleep.
