Cannes Premiere and Premise
The 2026 Cannes competition opened with Hirokazu Kore-eda’s *Sheep in the Box*. The film follows Otone (Haruka Ayase) and Kensuke Komoto (Daigo Yamamoto), a couple who lost their seven-year-old son Kakeru in a train accident two years earlier. A company called REbirth offers them a rented humanoid child whose appearance and memories are reconstructed from photographs and home videos. The robot is activated by a button on its neck, powers down at night, and is required to stay within thirty metres of the family. As the synthetic Kakeru integrates into daily routines, the parents confront divergent feelings of comfort and alienation.
Background & Context
Kore-eda, the 2018 Palme d’Or winner, said his concept originated after meeting a Chinese entrepreneur developing AI that simulates deceased individuals. He noted that such “resurrected dead” can “carry on conversations, not just reliving the past, but continuing to build new relationships and accumulate shared experiences.” The premise echoes earlier AI-themed cinema such as *A.I. Artificial Intelligence* and *Her*, but Kore-eda frames it within his long-standing focus on unconventional families, as seen in *Shoplifters* and *Like Father, Like Son*.
Key Figures & Groups
- Director: Hirokazu Kore-eda – veteran Japanese auteur, multiple Cannes laureate.
- Lead actors: Haruka Ayase (Otone), Daigo Yamamoto (Kensuke), Rimu Kuwaki (both the deceased Kakeru and the robot).
- Company in-film: REbirth – a fictional startup that manufactures memory-infused humanoids.
- Critics: The Hollywood Reporter, IndieWire, Deadline, Screen Daily, Vulture, Micropsiacine.
Data & Statistics
- Japan reportedly operates up to 3,000 AI humanoid child units, according to local reporting.
- *Sheep in the Box* is one of 22 films competing for Cannes’s Palme d’Or, with the awards ceremony scheduled for May 23.
Why It Matters / Impact
The film raises a concrete ethical dilemma: “Is it really acceptable for the living to manipulate the existence of the dead however they please?” (Kore-eda). By dramatizing a commercial service that commodifies grief, the story forces viewers to consider how generative AI might reshape mourning, family structures, and the legal definition of personhood.
Official Statements & Responses
Kore-eda emphasized that the service depicted “would definitely have people who want to use it,” while questioning its moral implications. Actress Haruka Ayase described Otone’s arc as a transition from “time has stopped” to a gradual healing through interaction with the robot, noting that the AI “makes us question what true relationships are.”
Criticism & Opposition
Critical reception is mixed. The Hollywood Reporter labeled the drama “thematically woolly,” and IndieWire called it “emotionally stunted.” Deadline found it “strange but thoughtful,” whereas Screen Daily assigned a low 1.4/4 score, citing an overload of AI themes. Vulture praised its “tender and sun-dappled” tone, while Micropsiacine criticized it as “cold, repetitive” and under-utilized.
Conflicting Reports & Gaps
Reviews diverge sharply on the film’s emotional resonance, ranging from “drippy” to “thoughtful.” No source provides audience reaction data or verification of the 3,000 Japanese humanoids beyond anecdotal reporting, leaving the real-world feasibility of REbirth’s model unclear.
