The Astronaut

The most terrifying thing about space isn't the vast, freezing nothingness or the way your blood might boil if your suit tears; it’s the silence that follows you home. In The Astronaut, Kate Mara spends a lot of time sitting in that silence, and I found myself leaning into the screen, waiting for the other shoe—or perhaps an extra-terrestrial limb—to drop. It’s a lean, 90-minute exercise in containment that feels like a spiritual cousin to those high-concept Twilight Zone episodes that relied more on a sweaty brow than a massive CGI budget.

I watched this while nursing a cup of peppermint tea that had gone tragically lukewarm, and honestly, the tepid temperature of my beverage weirdly matched the cold, clinical aesthetic of Sam Walker’s high-security recovery house. There’s something undeniably "streaming era" about the production—it’s polished, tightly controlled, and clearly designed to thrive on a smaller screen where intimacy translates to intensity.

The Loneliness of the Long-Distance Flyer

Sam Walker (Kate Mara) is the sole survivor of a mission gone wrong, and upon her return, she’s whisked away to a "rehabilitation" facility that looks more like a high-end IKEA showroom with bulletproof glass. Kate Mara has always been an actress who carries a certain internalised vibration; she’s excellent at playing characters who are vibrating with a secret trauma. Here, she’s tasked with carrying the bulk of the film's emotional weight as Sam begins to suspect that the "medical testing" overseen by General William Harris (Laurence Fishburne) is actually a cover for something much more predatory.

Laurence Fishburne could read a grocery list and make it sound like a national security briefing. He brings a much-needed gravity to the proceedings, playing Harris with a paternalistic edge that never quite masks the threat beneath. It’s the kind of performance that reminds you why we still need veteran character actors to anchor these mid-budget thrillers; he provides the "prestige" glue that holds the more fantastical elements together. When he and Kate Mara share the frame, the movie moves from a standard "is she crazy?" thriller into a genuinely engaging power struggle.

Practical Shadows vs. Psychological Shivers

Director Jess Varley, making her solo feature debut here, clearly understands that in horror, what we don't see is usually more expensive and more effective than what we do. The film plays with the architecture of Sam’s confinement—the way shadows stretch across a modern kitchen or the distorted reflections in a sterile pool. There’s a specific sequence involving a sensory deprivation tank that I found particularly effective, playing on that primal fear of being trapped in the dark with something you can’t quite name.

The "creature" elements, when they do appear, lean into a more grounded, textured approach. It’s refreshing to see a 2025 release that doesn't over-rely on weightless digital monsters, opting instead for a sense of physical presence that feels like it could actually be occupying the same room as the actors. Gabriel Luna pops up as Mark, Sam's husband, providing the emotional tether to "normal" life, but the film is at its best when it leaves Sam isolated. The sound design is the real MVP here, using ambient drones and sudden, sharp mechanical noises to keep the audience as jumpy as the protagonist.

A Modern Mid-Budget Curiosity

In an era where we are constantly bombarded by three-hour franchise epics, a 90-minute thriller that stays in its lane feels like a minor miracle. It’s a film that knows exactly what it is: a moody, atmospheric "What If?" scenario that doesn't feel the need to build a cinematic universe. Apparently, the production was a family affair behind the scenes, with Cameron Fuller (son of producer Brad Fuller) producing, which might explain why it feels like a throwback to the tight, commercial thrillers of the early 2000s—think Panic Room with a cosmic twist.

The inclusion of Macy Gray as Val is one of those "only in an indie-adjacent sci-fi" casting choices that I absolutely love. It’s weird, it’s unexpected, and it adds a layer of texture to the world-building that makes the facility feel like a real place rather than just a set. While the film doesn't necessarily reinvent the "alien stowaway" trope, it handles it with enough craft and performance-driven tension to justify the ride. It’s basically '10 Cloverfield Lane' if the bunker was a government safehouse and the monster had a NASA clearance badge.

The Astronaut succeeds because it respects the audience’s time and the lead actress's ability to hold a close-up. It’s a solid, well-crafted thriller that understands how to use a limited budget to create a maximum sense of unease. While it might not have the historical weight of the sci-fi classics it references, it’s a perfect example of how contemporary cinema can still deliver a satisfying, self-contained story without the bloat of modern IP filmmaking. If you’re looking for a sharp, slightly paranoid way to spend an hour and a half, Sam Walker’s return to Earth is a trip worth taking.
