A modestly budgeted sci-fi called Osiris has quietly muscled its way into Prime Video’s weekly top 10. Originally bound for theaters and barely glimpsed on US screens last summer, it’s finding a second life online. Backed by a survival premise that strands a special forces unit inside an alien craft and pits them against relentless hunters, the film leans on tight corridors and old-school menace. Linda Hamilton of Terminator fame stands out among a cast led by Max Martini and Brianna Hildebrand, while director William Kaufman channels shades of Predator and Stargate on a $6 million canvas that even teases a sequel.

A sci-fi surprise: Osiris finds its home online

When a film designed for theaters takes a detour to streaming, the outcome can be unexpected. Osiris, a science fiction feature with big ideas and a modest scope, landed on Amazon Prime Video in early 2026 and quickly climbed into the platform’s weekly top 10. Originally aimed at multiplex screens, it instead found momentum by tapping a broad online audience hungry for compact, high-concept thrills.

A mission gone wrong: the gripping premise

Osiris follows a special forces unit dispatched on a high-risk operation that spirals when the team is abducted by an alien spacecraft. Forced into a deadly game against extraterrestrial hunters, they fight to outwit an enemy that stalks them at every turn. The setup nods to Predator and Stargate, but the film leans on pace and pressure rather than spectacle. Working with just 6 million dollars, the script funnels tension into terse confrontations and survival-driven choices.

A once and future soldier

The cast is a clear asset. Linda Hamilton, forever linked to Terminator, inhabits a steely former Russian soldier who anchors the human stakes. Opposite her, Max Martini commands the squad with bruised authority, while Brianna Hildebrand injects sharp, youthful resolve. At the helm, William Kaufman directs and co-writes with Paul Reichelt, shaping a contained thriller that favors character pressure over pyrotechnics.

Breaking barriers, not budgets

What distinguishes Osiris is focus. Confinement to claustrophobic spaces becomes both visual signature and pragmatic constraint. Some critics flagged the limited polish of the effects, yet others welcomed its throwback pulse to 90s-style sci-fi where ingenuity and momentum carry the load. An open-ended finale leaves the door ajar for continuation, without undercutting the stakes of this chapter.

From a few theaters to global streams

After a small run in select U.S. theaters during summer 2025, the movie barely registered. Its shift to Amazon Prime Video in early 2026 changed the trajectory, delivering a global audience and a second life among sci-fi fans drawn to retro-tinged adventures. For viewers missing muscular interstellar thrillers, Osiris scratches that nostalgic itch while quietly setting up what might come next.
