00:03A package arrives at the door.
00:05It's heart-shaped, and when it opens, it releases this glowing hologram of a Luna moth.
00:10Just picture the absolute silent tension in that room for a second.
00:14You've got a grieving couple standing right there in the entryway of their home, staring
00:18down at this incredibly strange delivery.
00:21I mean, they've literally been waiting for this moment.
00:23So the box opens up, and standing right there, right in front of them, is their son.
00:28Well, okay, not exactly their son.
00:31It's a replica.
00:32A humanoid robot that has been painstakingly customized using two years worth of photos,
00:37videos, and literally every single digital trace these parents kept of the boy they lost.
00:42He looks exactly like their son, Kakarou.
00:45He talks exactly like Kakarou.
00:48Okay, let's dive into this.
00:50Welcome to our explainer on Sheep in the Box, Grief and Artificial Grace.
00:54Today, we're unpacking the deeply moving and honestly highly debated film written and
00:59directed by Palme d'Or winner Hirokazu Kureta.
01:01This one premiered in the main competition at Cannes, and it is officially hitting US
01:05theaters on July 24th, 2026.
01:07And look, rather than giving us your standard, run-of-the-mill sci-fi thriller about evil
01:11AI taking over, Kureta has crafted this quietly devastating look at human grief.
01:21So, we find ourselves in Japan in the near future.
01:24And importantly, it's not some dystopian wasteland, right?
01:27It's basically just a half step away from our current reality.
01:31We've got drones handling deliveries, robot crossing guards out there helping kids cross
01:35the street, and right in the middle of this totally recognizable world operates a company
01:39called Rebirth.
01:40Their process is just chillingly sterile.
01:43First step, they collect photos, videos, and digital traces of the deceased.
01:47Step two, they feed all of that raw data into their generative AI system.
01:52And step three, they produce a customized humanoid replica that they basically offer on a rental
01:56basis to bereaved families.
01:58What makes this so wild is that Kureta actually pulled this idea from real, actual businesses
02:03operating today in China that create AI versions of people who have passed away.
02:07In the film, the tech isn't framed as evil or malicious.
02:10It's really just a tool, plainly presented to a grieving couple.
02:14Section two, two ways to grieve, On and Kensku.
02:18So when this robot child walks through the door, we hit the central conflict of the story.
02:23You have two people living in the exact same house, suffering from the exact same tragic
02:27loss.
02:27But they experience completely different relationships to the technological interventions
02:31standing right there in their hallway.
02:32The divide between them is just striking.
02:34The mother, Oton, played so beautifully by Haruka Iese, she just exhibits total, absolute
02:40acceptance.
02:40She adjusts her entire rhythm to match this robot.
02:43She even refuses to eat when she realizes the machine can't eat.
02:45She is essentially giving up her own time as a living human being to completely submit
02:50to the illusion.
02:51She knows it's a robot.
02:52She doesn't care.
02:53She welcomes it anyway.
02:54But then you have the father, Kensuke, played by the comedian Daigo.
02:57And he represents absolute, clinical rejection.
02:59He is just deeply uncomfortable, coldly dismissive, and he's constantly reminding himself that
03:04this thing is just a machine.
03:06He rejects it completely, even when it looks right at him and calls him dad.
03:09And that brings us to this truly devastating realization.
03:12The logic of grief completely overrides the logic of reason.
03:16For Kensuke, reason holds up pretty well until this one critical turning point on a train.
03:21The robot just casually starts reciting the names of the stations on the line, in the
03:25exact same way his dead son used to do.
03:27And in that highly specific moment, Kensuke finally breaks.
03:30He laughs despite himself.
03:31He is moved despite himself.
03:33His armor of cold logic just completely shatters under the massive weight of his raw grief.
03:38Section 3.
03:39The Robot's Secret Life.
03:41Kakarou becoming himself.
03:43Now what's really interesting about this slide is, while the parents are projecting all their
03:48mourning onto him, the robot, who is portrayed with just impossible complexity by the child
03:54actor, Remove Kawaki, is actually undergoing his own incredibly unsettling evolution.
03:59He begins to actively stray from the human Kakari's memories.
04:03Like, he becomes fascinated by planes, shaving wood at his father's workplace.
04:07He is visibly impacted by his mother's modernist architecture.
04:10He is literally moving away from his programmed data.
04:13This humanoid that they rented specifically to restore their past is actively creating an
04:18entirely new future for himself.
04:20He's becoming something their actual son never even was.
04:23And while he's evolving like this, he actually starts slipping away from the parents to go
04:28silently meet up with other grief replica robots in the margins of the adult world.
04:32Which leaves us with this haunting, totally unanswered mystery.
04:36What does a robot, built entirely from a dead child's data, need from other robots built
04:41the exact same way?
04:43Like what are they even saying to each other?
04:44The film boldly refuses to answer this.
04:47It just lets the mystery sit right there in the open for us to chew on.
04:51Section 4.
04:52The Little Prince Metaphor The Empty Container
04:55To really grasp what Coretta is doing here, we have to look at Antoine de Saint-Exupéry's
05:00classic tale, The Little Prince.
05:02It's actually a book the mother reads to the robot within the film itself.
05:05So in that classic story, the narrator is asked to draw a sheep.
05:09But none of the drawings are quite right.
05:10Finally, he just draws a box and tells the prince the sheep is inside.
05:14And the little prince is totally satisfied because he can project the exact sheep he desperately
05:18wants to see right into that empty box.
05:21The robot Kakeru is exactly this.
05:23He is an empty container.
05:25His contents, his meaning, they are defined entirely by the emotional projections of whoever
05:30happens to be looking at him.
05:31Just look at how this projection plays out for everyone involved.
05:34Oh Satone looks at the robot and she clearly sees her lost son.
05:39Kinsuke looks at the exact same robot and sees this profoundly uncomfortable reminder
05:44of loss.
05:45The company, Rebirth, they just see a commercial product.
05:48And the film itself sees the philosophical problem.
05:51Nobody actually sees what the robot truly is.
05:54Honestly, perhaps the robot doesn't even know himself.
05:57AI grief technology, at least as it's presented here, is really just a container for your own
06:02personal projection.
06:07So this whole concept of projection incredibly spilled right over into the real world after
06:13the film's premiere at Cannes.
06:15Just look at the Rotten Tomatoes consensus.
06:17It reveals this aggressively divided response.
06:2048% fresh, 52% rotten.
06:23It turns out audiences and critics were just completely split on the film's meaning and its
06:28value, literally projecting their own expectations right onto Coretta's work.
06:33To understand this massive split, we have to look at two distinct camps.
06:37On one side, we have what we'll call the AI critics.
06:40These viewers were highly frustrated by the film's refusal to address hard, modern AI ethics.
06:45You know, the broader moral implications and the real societal impact of the technology.
06:50But then on the other side, we have the grief critics.
06:52This camp was deeply, deeply moved by the film.
06:55They viewed it as a beautiful, delicate sci-fi story that is focused strictly on how humans
07:00use technology to manage profound loss.
07:03And this whole debate reveals a really fascinating truth.
07:06Both audiences are right about what they got.
07:09But only one of them is wrong about what they asked for.
07:12If you go into this film expecting some rigid textbook ethical debate on artificial intelligence,
07:16you are absolutely going to be frustrated.
07:19But Coretta was never making an AI ethics movie.
07:21He is continuing his career-long exploration of constructed families, which is the exact
07:26same theme we saw in his previous masterworks like Shoplifters and Monster.
07:29He built a child, literally, out of other people's projections.
07:32Two years after losing their son, these parents opened a box.
07:37And what came out of it wasn't their son.
07:39But it wasn't not their son either.
07:43That is what grief looks like when the future arrives before you are ready for it.
07:47It is profoundly heavy.
07:49So as we wrap up this explainer today, I want to leave you with one final question to ponder.
07:54Does the box metaphor work for you?
07:56Or is the film reaching for a meaning it hasn't quite earned?
07:59When you look at the robot cockaroo, do you see the profound depths of human mourning or
08:04just empty code?
08:06Really think about it, because in the end, maybe the sheep really was inside the box all
08:10along.
08:11It just wasn't the one anyone expected.
08:13Thanks for opening it up with us today.
