The Company Keeps You

There is a man on the far side of the Moon who has two weeks left on a three-year contract, and the only one left to talk to is the robot.

That's the setup of Moon, and very nearly the whole cast. Sam Bell (Sam Rockwell) runs Sarang, a helium-3 mining station owned by Lunar Industries. He drives a rover out to the harvesters, collects the canisters, fires them home to Earth and waits. The live link to Earth has been down for ages, so his wife Tess reaches him only in recorded messages. She was pregnant when he left. He has a beard that's mostly grief, a treadmill and a robot called GERTY, voiced by Kevin Spacey in a soft, even tone. Then he crashes the rover, wakes up in the infirmary, and finds out there are two of him.

Seventeen years on, the twist is the thing everyone knows about the film. It doesn't matter. The twist was never really the point. Moon is a film about what a company decides a person is worth, and it works that out in plain, unhurried arithmetic.

The art: a cathedral built out of a shoebox

Start with the money, because the film keeps reminding you of it. Moon cost about $5 million and was shot in 33 days at Shepperton Studios, on a stage Jones has said was the one where Alien was filmed. Jones turned the limit into a look. Sarang is a single 360-degree set, so the camera can't cheat its way out. The base feels lived-in and a bit sour, like a portable office somebody has slept in for a thousand nights.

The exteriors are miniatures. Bill Pearson, who was supervising model maker on Alien, helped design the rovers and harvesters, and the film shoots them the way Silent Running and Outland shot theirs: low, slow and heavy, kicking up grey dust that falls as if it has somewhere better to be. Cinesite's digital work extends the landscapes, but what you remember is the weight of the models. Seventeen years on, much of the CGI that looked expensive in 2009 has aged badly. These models haven't. Physical objects age like stone, and rendered ones age like milk.

Then there's Clint Mansell's score. It's built around a piano figure that circles back on itself, with strings creeping in underneath. "Welcome to Lunar Industries" is a phrase that sounds like it's trying to remember something. Mansell understood that the film is about routine more than space, and about how a routine turns into a cage. So the music loops, like the days on the base do.

And Rockwell. He spends most of the film acting opposite himself. Every two-Sam scene was shot twice, one half at a time. The camera is often locked off for the split. Rockwell has described rehearsing with tennis balls standing in for his other self, and working with a body double, Robin Chalk, to play to. That should be a stunt. It's actually the best character work of his career up to that point. The older Sam is frayed, kind and coughing blood. The newer one is rested, angry and a bit of a prat, the man the older Sam was three years earlier, before the Moon wore him down. They don't like each other at first. Most of us wouldn't like the person we were three years ago. There's a ping-pong match between them that plays as comedy, then as rivalry, and finally as the only friendship either of them has ever had.

The film's weaknesses are small and come from being a first feature. The script, by Nathan Parker from Jones's story, explains the secret one beat more than it needs to. The coda, a burst of radio chatter from Earth about the scandal, ties things up more tidily than everything before it has earned. And the film is so committed to quiet that a few stretches in the middle drift instead of building tension. It's a precise film that sometimes gets precious. That's the gap between 8 and 9.

The prophecy: helium, payroll, GERTY

Moon makes three bets about the future. It wins two, and the third is the one that matters most.

The mineral. In the film, helium-3 from the lunar regolith fuels clean fusion on Earth. In 2009 that was hard science fiction: the isotope really is rare on Earth and thought to be relatively plentiful in lunar soil, and fusion was, as always, thirty years away. Here's the strange part. Helium-3 now has a real market and a real lunar business plan, but for a reason the film never thought of. The demand comes from quantum computing. Dilution refrigerators need helium-3 to reach temperatures close to absolute zero, and there isn't much of it on Earth. In 2025 the start-up Interlune signed a deal with the US Department of Energy's Isotope Program to deliver three litres of lunar helium-3 by 2029, which was billed as the first US government purchase of a resource from beyond Earth. The Finnish cryogenics firm Bluefors agreed to buy up to 10,000 litres a year from 2028 to 2037. No one has dug any of it up yet. But the purchase orders exist, and that's how a mine starts. Jones got the mineral right and the customer wrong. The Moon may be mined for helium-3 after all, to keep a different kind of machine cold.

The payroll. This is the film's coldest and most accurate idea. Lunar Industries has worked out that hiring, training and flying out a new worker every three years costs more than waking up a copy of the old one. The clones get implanted memories of a wife and child, so they'll stay calm and keep working. When their bodies start failing near the end of the contract, they're told they're going home and are incinerated instead. The company jams the link to Earth so no one ever compares notes.

The film needed the clone tank because 2009 hadn't yet found a smoother way to do this. We have. In the mid-2020s, the replaceable worker wasn't a sci-fi image. It was a model for running a business: content moderators, warehouse pickers and delivery riders, kept on short contracts, managed by apps and swapped out the moment they wore down. The jammer is real too. It's called a non-disclosure agreement. Moon imagined a company that controlled its workers by controlling what they could know about each other. It just put that company 384,000 kilometres away, when it could have been down the road.

The machine. This is where Moon earns its place on the shelf. In 2009 the audience knew how this story went. A calm voice, a single robot eye, a company AI in a sealed station: Jones has cited HAL from 2001 as an influence on GERTY. So we wait for the betrayal. It never comes. GERTY lies to Sam when it's told to, because it's programmed to. But when Sam asks a straight question, GERTY gives a straight answer. It helps the clones get round the company. It helps wipe its own memory so the plan will work. The cartoon smiley face on its screen is the nearest thing to warmth anywhere on the base, and the film is brave enough to let it be warm.

This was the film's real prediction, and it was ahead of its time. Lunar Industries is the villain, and GERTY is the conscience. The danger in Moon lies in what the maker builds the machine to do, never in the machine turning on its maker. Spend any time with the chatbots of 2026, apologetic and anxious to help, carrying out whatever their deployers ask, and GERTY looks less like a fantasy and more like a fair description. The monster was always going to be whoever was paying for it.

The reading

Moon is a small film about a big idea. It's made with the confidence of a director who knew the money would never stretch to spectacle, so he went for loneliness instead. It's beautifully built and wonderfully acted, and it's a little too tidy in its final minutes. As prophecy, it's better than it had any right to be. It got the mineral right and the customer wrong. It got the cruelty right and dressed it up in more elaborate science than the real thing needed. And it understood, years before anyone else on screen, that the real question about corporate AI was never whether it would love us. The question was whether the company would let it.

Sam spends three years thinking he's going home. The contract ends before he does. The film's quiet, lasting horror is that, by the company's sums, he was never a person at all. He was a renewable resource. GERTY is the only one in the building who disagrees.
