Amazon MGM Studios’ Project Hail Mary moved from theaters to streaming with a June 18, 2026 debut on MGM+, giving U.S. viewers a subscription option after its theatrical and on-demand runs. The hail mary movie, based on Andy Weir’s best-selling novel and starring Ryan Gosling, later expanded to Prime Video, making the amazon project hail mary streaming rollout a two-step release across Amazon’s entertainment ecosystem.
When did Project Hail Mary start streaming?
Project Hail Mary began streaming on MGM+ on Thursday, June 18, 2026, after Amazon MGM Studios announced the date on June 10. That placement gave MGM+ the first subscription-streaming window before the film’s broader availability on Prime Video. For U.S. viewers, it meant the first place to stream the movie as part of a subscription was MGM+, not the standard Prime Video library.
The timing followed a theatrical-first strategy. Reports described the MGM+ debut as arriving after roughly a 90-day theatrical window, a familiar pattern for major studio films that move from cinemas to premium digital rental or purchase, then to subscription streaming.
Why the MGM+ window matters
The release drew attention because Amazon owns both Prime Video and MGM+, leading some viewers to expect the film to land directly on Prime Video. Instead, the company used MGM+ as the first streaming home for one of its highest-profile sci-fi releases of the year. That approach can help drive attention to MGM+ while still keeping the title within Amazon’s broader streaming portfolio.
Amazon later promoted the movie’s Prime Video availability, saying Project Hail Mary was streaming on Prime Video worldwide and identifying it as one of the year’s top box-office performers. Amazon’s own update reported more than $680 million globally, including over $343 million in the United States and Canada, following its March 20 domestic debut.
Key details for U.S. viewers:
- First subscription-streaming stop: MGM+, beginning June 18, 2026.
- Later streaming expansion: Prime Video availability followed, according to Amazon’s viewing guide.
- Story source: The film adapts Andy Weir’s novel about a high-stakes mission to save Earth.
- Lead cast: Ryan Gosling headlines the movie, bringing wider mainstream attention to the sci-fi adaptation.
