Oxygen

There is a specific kind of panic that sets in when you realize your world has shrunk to the size of a coffin, and unfortunately for Mélanie Laurent, that coffin is full of flickering blue lights and a very polite computer that keeps telling her she’s about to suffocate. If you’ve ever felt the walls closing in during a long flight or a crowded elevator, Oxygen (or Oxygène) is designed to take that knot in your stomach and pull it tight for a hundred minutes.

I watched this while wearing a weighted blanket that was slightly too heavy for the room temperature, and for a few minutes, I genuinely had to toss it off just to convince myself I wasn't also trapped in a high-tech freezer. That’s the power of what Alexandre Aja has built here—a film that turns a single, cramped location into a sprawling psychological battlefield.

The Splatter King Goes Small

For those of us who grew up on the "New French Extremity" movement of the early 2000s, the name Alexandre Aja usually conjures images of industrial-sized buzzsaws and fountains of corn syrup blood. He’s the guy behind High Tension and the surprisingly gnarly Crawl. But with Oxygen, Aja trades his chainsaw for a scalpel. This is a pandemic-era production in the truest sense—filmed in July 2020 under strict protocols—and it uses that "locked-in" energy to its absolute advantage.

The premise is deceptively simple: A woman (Liz) wakes up in a cryogenic pod with no memory of who she is or how she got there. Her only companion is M.I.L.O. (Medical Interface Liaison Officer), an AI voiced by the legendary Mathieu Amalric. M.I.L.O. is helpful, informative, and utterly indifferent to the fact that Liz’s oxygen level is ticking toward zero. It’s a classic "bottle" movie setup, reminiscent of Ryan Reynolds’ Buried, but with a high-concept sci-fi sheen that feels very much of our current streaming-dominant era.

The Laurent Masterclass

In a film like this, the entire enterprise lives or dies on the lead performance. If we don’t buy the panic, the movie is just a series of blue LEDs and technical jargon. Mélanie Laurent is nothing short of a miracle here. She’s acting with her eyes, her breath, and her fingertips. Because she’s strapped into a medical unit for the vast majority of the runtime, she has to convey a lifetime of realization, terror, and eventual resolve within a few square feet of space.

What I found most impressive was how Aja and screenwriter Christie LeBlanc avoided the typical traps of the genre. Usually, characters in these films spend thirty minutes just screaming at the walls. Liz, however, is a scientist. Watching her transition from raw, animalistic terror to analytical problem-solving is incredibly satisfying. She uses M.I.L.O. to search for her own identity, placing frantic calls to a world she can’t remember, trying to piece together a puzzle where the pieces are literally being deleted in real-time. Amalric’s voice work is the perfect foil; he sounds like he’s trying to sell you an expensive espresso machine while calmly explaining that your lungs are about to fail.

A Modern Mystery for a Digital Age

While the film starts as a survival thriller, it eventually pivots into something much more ambitious. I won't spoil the turn, but Oxygen understands that contemporary audiences are savvy. We’ve seen the "it was all a dream" or "she’s in an asylum" tropes a thousand times. Most 'one-room' thrillers run out of gas by the forty-minute mark, but Aja keeps the pedal down by constantly expanding the stakes. Just when you think you’ve mapped out the boundaries of the story, the film pulls the camera back—both literally and figuratively—to reveal a much larger, bleaker, and more fascinating world.

This is where the film feels most "now." It engages with our current anxieties about environmental collapse, the ethics of AI, and the isolation inherent in our tech-dependent lives. It’s a Netflix-original that actually feels like it was designed for the platform, rather than a discarded theatrical release. The cinematography by Maxime Alexandre is remarkably creative given the limitations; he finds ways to make the inside of a plastic pod look like a neon-soaked cathedral one minute and a claustrophobic tomb the next.

The film isn't perfect—there are a few moments in the second act where the pacing stutters as Liz waits for M.I.L.O. to process data—but the emotional payoff is surprisingly resonant. It’s a horror movie where the "monster" is simply the absence of air, and the "hero" is the human will to remember why that air is worth breathing in the first place.

Oxygen is a lean, mean, and surprisingly thoughtful addition to the sci-fi thriller canon. It proves that you don't need a hundred-million-dollar budget or a sprawling galaxy to tell a story that feels epic; sometimes, all you need is a great actor and a very small box. It’s the perfect watch for anyone who wants a "smart" thriller that doesn't skimp on the tension, just maybe keep a window open while you watch it. You’ll appreciate the breeze.
