A woman opens her eyes inside a sealed capsule with no idea how she got there, and the air inside is already running low — that single fact drives every minute of Oxygen.
What is Oxygen about?
Trapped in a cramped medical pod with her memory wiped clean, the woman at the center of Oxygen has almost nothing to work with except a failing life-support display and a voice assistant that answers her questions only so far. Every attempt to piece together who she is and why she's confined competes directly against a shrinking supply of breathable air, so the film turns a search for identity into a race against a countdown that never lets up. Director Alexandre Aja keeps the frame tight around her for most of the runtime, using the pod's narrow walls to make the mystery feel as physically confining as the oxygen problem itself.
About the cast
Mélanie Laurent carries the film largely on her own as the woman in the capsule, with Mathieu Amalric, Malik Zidi, Marc Saez, Vincent Maraval, Brahim Chioua, Noémie Devide, and Grégory Levasseur rounding out the cast around her. Given the pod's single-location setup, most of these roles surface through recordings, calls, and fragments rather than shared scenes on screen.
Context & significance
Oxygen is a French production released in 2021, blending Drama, Fantasy, Sci-Fi, and Thriller elements into a single-setting survival story rather than sticking to one genre lane. That mix lets it pivot between a grounded medical emergency and stranger, more speculative territory as the woman's fragmented memory resurfaces. At around 100 minutes, the film keeps a tight, contained shape that suits its one-location premise, letting tension build through pacing and sound design rather than a widening cast of locations.
