Project Hail Mary streaming now runs through one company: Amazon. The film began streaming on Prime Video on July 3, 2026. It first stopped on the MGM+ channel on June 18, 2026. Amazon then opened the doors for its main subscriber base. The movie adapts the Andy Weir novel, with Phil Lord and Christopher Miller directing.
The streaming debut closed out a huge theatrical run. Variety reported a global gross of 680 million dollars. The film also opened to 80.5 million dollars at home, the biggest launch in the studio's history. Ryan Gosling stars as Ryland Grace, a teacher who wakes alone on a spaceship. He has no memory of how he got there. For related coverage, see X (2022 film) Review: Ti West's Slasher Cuts Both Ways.
The theatrical window came first
Amazon MGM put the film in theaters on March 20, 2026. The official Prime Video page still lists that date on its release card. The movie then held screens through spring. Strong reviews and steady word of mouth kept it in play before any home viewing began.
Lord and Miller worked from a script by Drew Goddard. Sandra Hüller plays the scientist behind the desperate mission. The alien Rocky, performed by James Ortiz, drew praise of his own. That cast gave the film broad appeal and long legs at the box office.
How Amazon structured the rollout
The home plan followed a clear order. The title landed on MGM+ first, on June 18, 2026. That channel serves as the studio's own premium shelf. Two weeks later, on July 3, it joined the main Prime Video catalog. Variety logged both dates in its streaming coverage.
The July arrival turned the film into the flagship draw of the summer slate. The whole chain, from ticket to stream, sits inside one roof. That is the pattern for the studio's biggest titles. No rival service held a window at any point in the run.
One caveat belongs in every window talk. Catalogs shift by territory and by date. The Prime Video shelf in one country may not match the shelf in another. Viewers abroad should check their local Amazon storefront first.
The film behind the numbers
Weir's novel spent years on bestseller lists before this adaptation reached screens. The story plays as a rescue mission with a comic streak. Gosling carries long stretches alone, talking to a rock that talks back. Critics liked the mix, and audiences came back for repeat rides.
The box office told the rest of the tale. An 80.5 million dollar opening gave the film instant scale. It then held its ground week after week. By the time streaming began, the movie stood among the year's top earners worldwide.
The window at a glance
Here is the whole run on one line. Theaters opened on March 20, 2026. The MGM+ channel followed on June 18. Prime Video came last, on July 3. Each step kept the film inside Amazon's walls from first ticket to final stream.
The gaps tell their own story. A full spring run in theaters came first. A short premium-channel stop came second. The wide catalog release closed the plan. Subscribers who waited for the last step got the cheapest path of all, and the theater count stayed strong in the meantime.
The novel's path set this one up. Weir's book arrived in 2021 and became an instant hit with space fans. The film kept that base and added a global one. By streaming day, the title had crossed from hit to event.
Is it worth a Prime subscription this month?
For science fiction fans, the math is easy. The film streams inside the base catalog, not behind a channel upsell. One month covers the movie and the rest of the Weir shelf for a double feature. New subscribers get the full theatrical version at no added fee.
Casual viewers get a clean deal too. The MGM+ cut stays on its own channel with extra features. The main version needs no add-on at all. Renters can still find the film on the usual storefronts for a small fee.
Conclusion
Project Hail Mary streaming lives on Prime Video. It has been there since July 3, 2026, after a June 18 debut on MGM+. The theatrical run began on March 20 and brought 680 million dollars worldwide. For subscribers, the film is the anchor of the summer catalog. The dates rest on the studio's own page and trade reporting. Territory shifts remain the only moving part worth watching.
