South Korean director Yeon Sang-ho's psychological thriller "Paradise Lost" opens in North American theaters on Friday after premiering at the Toronto International Film Festival. The film stars Kim Hyun-joo as Ryu So-young, a mother who relies on an AI recreation of her abducted son Sun-woo, forever 10 years old, seen through augmented reality glasses.

Why it matters

The release continues Yeon's exploration of artificial intelligence, following his 2023 Netflix film "JUNG_E" and his 2026 zombie thriller "Colony", which premiered at the Cannes Film Festival. The film raises questions about grief and memory as AI tools become more capable of recreating the people we have lost.

The film's ninth-year timeline and 100-person blind preview survey anchor its release, while its commercial results remain unknown until theaters open. Its box office performance is not yet available, and the preview's findings have not been publicly detailed.

The players

Yeon Sang-ho

South Korean director and screenwriter known for exploring artificial intelligence themes across his films, including the 2023 Netflix film "JUNG_E".

Kim Hyun-joo

South Korean actress who plays Ryu So-young, the mother at the center of the psychological thriller.

The details

Yeon Sang-ho, who never formally studied screenwriting, drew the story from a roughly three-page tale written by his mother, a homemaker who worked as a cleaner. The film's title refers to John Milton's epic poem about humanity's expulsion from paradise, and the lead role of the real Sun-woo, who returns as a grown stranger, is played by Bae Hyeon-seong.

Timeline

  1. 2023: Netflix released "JUNG_E", an AI-themed Yeon film.

  2. 2026: "Colony" premiered at the Cannes Film Festival.

  3. Friday: "Paradise Lost" opens in North American theaters.

Legacy Thread

"Paradise Lost" extends the artificial intelligence theme Yeon Sang-ho explored in his 2023 Netflix film "JUNG_E", shifting it from a broader sci-fi frame toward a personal story about grief. It follows the AI-themed direction that also runs through his 2026 zombie thriller "Colony".

Viewers can see "Paradise Lost" in North American theaters starting Friday. The film's availability beyond theatrical release has not been announced.

The takeaway

The film pairs a futuristic premise with a deeply human question: whether a recreated presence can truly ease the absence of someone lost. Readers interested in the theme can weigh how AI tools might reshape grief.
