Project Hail Mary Hits Streaming on MGM+ — Ryan Gosling's $650M Sci-Fi Epic Is Finally Available at Home

If you somehow missed Project Hail Mary in theaters, or just really want to rewatch Ryan Gosling try to save humanity while floating alone in space — good news. The biggest sci-fi blockbuster of 2026 finally hits streaming on June 18, 2026, and it's landing on MGM+ (not Amazon Prime Video, which might confuse some of you).

Why Everyone Is Talking About This Movie

Directed by the filmmaking duo Phil Lord and Christopher Miller — the same creative minds behind The LEGO Movie and 21 Jump Street — Project Hail Mary is based on the bestselling novel by Andy Weir (author of The Martian). Gosling plays Ryland Grace, a middle school science teacher who wakes up alone on a spacecraft with no memory of how he got there, only to discover he's humanity's last hope.

The film has been an absolute juggernaut. Since its theatrical premiere on March 20, it's grossed over $655 million worldwide, making it the second-highest-grossing film of 2026 so far. Critics are equally impressed — the BBC gave it 4 out of 5 stars, calling it a "mind-stretching sci-fi" that manages to be "zippily entertaining" despite its two-and-a-half-hour runtime.

The Stellar Cast and Hidden Details

Gosling isn't alone in this space odyssey. Sandra Hüller — fresh off her Cannes-winning turn in Fatherland — plays a key role, and fans have been buzzing about a surprise voice cameo from Meryl Streep. There's also a clever Harry Styles connection: his song "Sign of the Times" is woven into the film's emotional core, reportedly thanks to Hüller's suggestion during production.

The movie also marks a rare win for theatrical releases in the streaming era — it proved that audiences will still show up in droves for original, intelligent blockbusters that aren't based on existing franchises. Alongside Obsession and Wuthering Heights (directed by Emerald Fennell and starring Margot Robbie), Project Hail Mary is being called one of only three 2026 releases with "future classic" written all over it.

Where and When to Watch

Here's the deal: Project Hail Mary streams on MGM+ starting June 18, 2026 — not Amazon Prime Video, despite both being under the Amazon MGM Studios umbrella. It's also available for digital rental via PVOD right now if you can't wait.

Whether you're a longtime Andy Weir fan or just someone who wants to see Ryan Gosling do what he does best — be quietly heroic in space — this is the weekend's must-watch. Grab your snacks, turn off your phone (ironic, given the movie's themes about screen time addiction), and let Gosling take you on the ride of a lifetime.
