Where to Stream Project Hail Mary: Prime Video Date and What to Know

Project Hail Mary is now streaming on Prime Video after its theatrical run, and it is also on MGM+. Here is where to watch Ryan Gosling's sci-fi hit and what it is about.

Published

One of the year’s biggest sci-fi movies is finally easy to watch at home: Project Hail Mary is streaming on Prime Video, following its March theatrical release. Here is exactly where to stream it, and a spoiler-free primer if you are coming to it fresh.

The quick answer

  • Streaming now on: Prime Video (added July 3, 2026) and MGM+ (added June 18, 2026)
  • Theatrical release was: March 20, 2026 (Amazon MGM Studios); some theaters are still showing it
  • Starring: Ryan Gosling, based on Andy Weir’s bestselling novel
  • Runtime commitment: a single feature film, no series homework

Where to stream it

  • Prime Video: included with Prime as of July 3, 2026, about 105 days after theaters. If you have Amazon Prime, you already have it at no extra cost.
  • MGM+: the film hit this smaller subscription service first, on June 18, 2026. If you happen to subscribe, it is there too.

You do not need both; Prime Video is the mainstream route. As always, availability can vary by country, so check the film’s page in your local storefront.

Still prefer a big screen?

The film was a major theatrical release (over 4,000 screens in North America at its peak), and some locations, including IMAX screens, have continued showing it. Check Fandango for any remaining showtimes near you.

What it is about (spoiler-free)

Based on Andy Weir’s novel (the author of The Martian), the story follows a lone astronaut who wakes up on a spacecraft far from Earth with no memory of why he is there, and must piece together a mission that turns out to involve the survival of humanity. Like The Martian, it leans on problem-solving, humor, and genuine science over doom. Ryan Gosling stars and the film was directed by Phil Lord and Christopher Miller.

The Prime Video arrival opened the film to a vastly larger audience than its theatrical run, and it has been climbing streaming charts since. If it has been popping up in your recommendations, this is why.

Bottom line

Prime subscriber? Just search “Project Hail Mary” in Prime Video and press play. No Prime? MGM+ has it, or catch a remaining big-screen showing while they last.
