Kore-eda's "Sheep in the Box" Brings AI and Grief to the Big Screen

Palme d'Or winner Hirokazu Kore-eda's latest film, the sci-fi drama "Sheep in the Box," made its US debut on July 23, 2026. The story follows a parent whose seven-year-old son dies in an accident and who then receives a robotic double of the child from an AI company. The Verge

In an interview conducted through an interpreter at Neon's offices days before the US debut, Kore-eda described the research behind the script. He consulted a robotics expert during the writing process and was told that "we would sooner have clones of humans than we would humanoid robots," because robots overheat. The detail is notable for anyone following humanoid robotics: heat dissipation remains a major obstacle for bipedal robots, and the film's premise of a convincing child-sized robotic stand-in is, by the expert's own assessment, further from feasibility than biological cloning.

Kore-eda also disclosed that he ran the "Sheep in the Box" script through ChatGPT, though the interview did not elaborate on what he used the tool for or how it shaped the final draft. The disclosure places Kore-eda among a growing group of creatives experimenting with large language models — AI systems trained on vast amounts of text — during the writing process, whether for structural feedback, dialogue iteration, or scene-level alternatives.

Grief is familiar territory for the director. Kore-eda noted that his first film, "Maborosi," dealt with the subject and that he read Elisabeth Kübler-Ross's books on grief work while making it. "Sheep in the Box" extends that preoccupation into speculative territory, asking what happens when AI tools are offered as instruments of mourning. The Verge
The film's premise is not purely speculative. Kore-eda cited two real-world precedents during the interview. In Japan, a famous deceased singer was re-created through AI and used to perform a new song. In Korea, a deceased young girl was re-created through AI to help her parents process their grief. Both cases involve rebuilding a person's likeness or voice from training data, deployed after death for emotional or commercial purposes. The technology behind these re-creations — voice cloning and generative facial animation — has matured rapidly, and the ethical and psychological questions Kore-eda dramatizes are ones that families, platforms, and regulators are already confronting. The Verge
The broader context here is that the entertainment industry's engagement with AI has moved well beyond behind-the-scenes tooling. Synthetic media — audio, video, or images generated by AI — is now a creative material, a posthumous services product, and a regulatory flashpoint simultaneously. When a filmmaker of Kore-eda's stature builds a feature around AI-mediated grief, uses ChatGPT in the writing process, and grounds the fiction in documented real-world cases of AI re-creation of the dead, the film functions as both artwork and cultural diagnostic.
Worth flagging is the gap between the film's technological premise and current engineering reality. The robotics expert's observation about overheating is not a minor caveat. Full-body humanoid robots capable of sustained, convincing interaction with a grieving parent are not on the near-term horizon, and the heat problem is one of several hard physical constraints — alongside power density, actuator fidelity, and the computing speed needed for real-time responses at the device itself — that separate today's humanoid platforms from anything that could plausibly pass as a child. The film's AI company supplying a robotic double is, at present, closer to science fiction than to an engineering roadmap.
What the film captures more plausibly is the human side of the equation. The emotional readiness of bereaved parents to accept a synthetic surrogate, and the commercial incentive for companies to offer one, are both already in evidence. Voice cloning and digital re-creation services exist today. The question "Sheep in the Box" appears to pose is not whether the technology will arrive but whether the arrival matters in the way its proponents suggest, or whether grief resists technological mediation in ways that no amount of model sophistication can resolve.
For technology professionals, the film is a useful cultural data point. It reflects how AI capabilities are being understood and narrated by artists outside the industry, and it foregrounds the social use cases — posthumous re-creation, grief companionship, surrogate identity — that will shape public expectations of AI systems regardless of what the technical state of the art actually permits.
