At No. 1 on Amazon Prime’s film chart as of May 4, 2026, The Astronaut landed straight to streaming on April 30 without a theatrical run. Kate Mara plays Sam, an astronaut suffering hallucinations after a crash, with Laurence Fishburne as her father, while user scores sit at 4.6/10 and comparisons swirl with 2026’s Project Hail Mary starring Ryan Gosling.
Amazon Prime’s latest sci-fi talking point skipped theaters yet raced to the top of the film charts. Kate Mara plays Sam, an astronaut shattered by a crash landing and stalked by hallucinations while holed up with her father, General Harris, portrayed by Laurence Fishburne. Forget the sunnier vibes of Ryan Gosling’s 2026 space saga with the similar name; this one leans into dread and memory’s unreliable edges. Viewers have propelled it to number one even as early user scores remain lukewarm, with streaming underway since April 30, 2026.
A new sci-fi thriller takes the top spot
There are weeks when you open Prime Video and the choice feels obvious. That is the case now with The Astronaut, a tense sci-fi thriller that has climbed straight to number 1 on Amazon Prime Video’s movie chart in the US. It never touched theaters, yet the momentum is real. Viewers are chasing a space mystery that keeps its secrets close.
Not another Ryan Gosling blockbuster
The title may ring a bell if you recently watched Project Hail Mary (2026) with Ryan Gosling, but the overlap stops at “astronaut.” Where Gosling’s crowd-pleaser soared on discovery and uplift, The Astronaut narrows the frame. It turns the screws quietly, trading spectacle for dread, and lingers on choices made in isolation, far from any cheering mission control.
The story behind Sam’s haunting descent
Kate Mara plays Sam, an astronaut who survives a violent return to Earth. Recovery should bring relief, yet her days blur with intrusive visions and stray fragments of memory. As she shelters with her father, General Harris, played by Laurence Fishburne, the film burrows into family trust and unreliable recall. Each answer Sam finds bends the previous truth, sometimes painfully so.
How does it rank among Prime Video’s top films?
As of May 4, 2026, The Astronaut sits at number 1 on Prime Video’s trending movies in the US. That ascent is striking for a straight-to-streaming release, and it comes amid divided reactions. According to Moviepilot (a European tracking site), early user scores average 4.6/10, suggesting a love-it-or-leave-it vibe. Curiosity, however, is winning for now, boosted by word of mouth and late-night watches.
What’s next for sci-fi on streaming?
Indeed, The Astronaut’s rise underscores how viewers embrace offbeat sci-fi when it lands at home first. Streamers keep filling that lane, stacking releases with big names and moodier risks through 2026. If you crave grounded tension over cosmic heroism, this film fits snugly between your weekend genre staples. And it is already waiting where most of us press play first: Prime Video.
