Ryan Gosling has been one of the most in-demand actors on the planet for the better part of the past two decades, and soon he’ll be humanity’s best chance at survival in Project Hail Mary, the upcoming book-to-screen adaptation of Andy Weir’s popular novel. One of the most anticipated sci-fi movies in quite some time, Phil Lord and Christopher Miller’s space-age adventure on the 2026 movie schedule sounds like an epic, emotional, and exhilarating journey to save the world.

If this is the first you’re hearing about what has the potential to be one of all-time great sci-fi films by the time it’s all said and done, don’t worry, because we’re about to break down everything we know about Project Hail Mary

What Is The Project Hail Mary Release Date

As great as it would be to see the Project Hail Mary release date on the 2025 movie schedule, the truth is we have to wait a little while longer, as the upcoming Ryan Gosling film won’t open in theaters until March 20, 2026.

Similar to the adaptation of Andy Weir’s The Martian, which primarily focused on Matt Damon’s Mark Watney spending time alone on Mars working on all types of experiments to stay alive long enough to be rescued after being left for dead by his crew, Project Hail Mary will see Ryan Gosling’s character alone deep in outer space after being sent on a mission to another star in hopes of saving Earth. Here’s the official synopsis from Amazon MGM Studios:

Science teacher Ryland Grace (Ryan Gosling) wakes up on a spaceship light-years from home with no recollection of who he is or how he got there. As his memory returns, he begins to uncover his mission: solve the riddle of the mysterious substance causing the sun to die out. He must call on his scientific knowledge and unorthodox ideas to save everything on Earth from extinction… but an unexpected friendship means he may not have to do it alone.

By the sounds of it, we’re in for a powerful, thrilling, and daring mission to save humanity…

The Project Hail Mary Trailer

While we still have months to wait for the Project Hail Mary movie to hit theaters, Amazon MGM Studios has given us a pretty substantial glimpse of what to expect from the movie. First, there was the teaser dropped over the summer that offered a small look into the upcoming sci-fi epic, which did a great job of setting the tone. But the real heavy-hitter came a few months later with a full trailer that might answer some major questions.

As seen in the video above, this new trailer follows Ryan Gosling’s Ryland Grace as he sets off on the mission to save humanity before it’s too late, as well as his time back on Earth before he became Earth’s last hope. There are still things we don’t know after watching the three-minute preview, but that makes it so much fun.

When the movie hits the big screen, it will feature a cast led by Ryan Gosling, who has been attached to star in the film as an actor as well as serving as one of its producers since March 2020, according to Variety. But the Barbie and The Fall Guy star won’t be alone in this space adventure. Let’s meet the rest of the Project Hail Mary cast.

Ryan Gosling will be taking on the role of Ryland Grace, a man tasked with traveling to deep space in hopes of saving humanity. This won’t be Gosling’s first space adventure, as he previously played Neil Armstrong in 2018’s First Man.

Sandra Huller, who received a lot of praise (and an Oscar nomination) for her performance in Anatomy of a Fall, also plays a key role in Project Hail Mary. In the upcoming sci-fi flick, Huller plays the administrator who is in charge of the mission sending Ryland deep into space.

Milana Vayntrub

Milana Vayntrub, who some may recognize as Lily in various AT&T ad campaigns over the past decade, joined the cast in June 2024, according to Deadline. In a June 2025 Instagram post, the actress said she was a “tiny part of this future classic of a movie.”

Also set to appear in Project Hail Mary are Liz Kingsman, Orion Lee, Ken Leung, Lionel Boyce, and James Ortiz, the latter of whom provided the puppetry work for Rocky, per IGN.

Andy Weir’s Project Hail Mary Was Published In May 2021 And Later Became A New York Times Best Seller

Some books exist for years or even several decades before they are adapted for the screen, but that isn’t the case with Project Hail Mary, as Andy Weir’s fourth novel was released less than five years ago. The sci-fi novel about an astronaut hurtling through space with the weight of humanity on his shoulders and a difficult task ahead of him was first published back in May 2021 and became a massive hit shortly thereafter.

Much like the film rights for Michael Crichton’s Jurassic Park, which Universal Studios acquired before the book was even published, Project Hail Mary’s rights were purchased by MGM a little more than a year before the sci-fi novel hit bookshelves. In March 2020, Deadline reported that the studio, which was acquired by Amazon one year later, paid a seven-figure amount to turn the then-unpublished novel into a movie, which really shows how excited they were to make this thing a reality.

Project Hail Mary spent a total of nine weeks on the New York Times Best Sellers list. It was later named GoodReads Best Science Fiction novel of 2021, in addition to numerous other accolades. If you watched the trailer and think the story looks good, there’s still plenty of time to read Andy Weir’s novel before the movie comes out.

Spotify Premium Subscribers Can Listen To The Project Hail Mary Audiobook At No Extra Charge

If you’re someone who wants to check out Project Hail Mary ahead of the adaptation, as well as a person who enjoys listening to audiobooks, you’re in luck. Everyone with a Spotify Premium subscription can listen to the audiobook version of Weir’s novel at no extra charge, though there is a slight caveat.

A premium account grants you 15 hours of free listening time for audiobooks each month, but Project Hail Mary is a little longer than 16 hours in length. If you time it right, you can start listening around the end of one month and then finish after the timer restarts. There’s also an option to add more listening time for a nominal fee.

Phil Lord And Chris Miller Are Co-Directing

Project Hail Mary won’t just have big talent in front of the camera when Ryan Gosling leads the cast, as one of the most successful filmmaking duos of the 21st century will be sitting behind the camera for this one. Phil Lord and Chris Miller are the directors behind the adaptation of Andy Weir’s novel.

Over the years, Lord and Miller have directed movies ranging from Cloudy with a Chance of Meatballs (another book adaptation) to 21 Jump Street (and its sequel, 22 Jump Street) to The Lego Movie. They’ve also had a hand in crafting some of the best Spider-Man movies, including the Spider-Verse films.

Drew Goddard Has Said Fans Of The Martian Will Like What He And Lord & Miller Are ‘Cooking Up’

Just like the acclaimed space movie The Martian, which was adapted to the screen by Drew Goddard, the Project Hail Mary screenplay was penned by the prolific screenwriter and filmmaker. When speaking with Variety in early 2025, Goddard revealed that fans of the 2015 Ridley Scott Golden Globe-winning sci-fi adventure film will like what’s to come, saying:

If you like ‘The Martian,’ I suspect you’re really going to like what we’re cooking up with ‘Hail Mary.’ Chris and Phil and I have known each other for decades now, and I love their work. And then obviously, Ryan Gosling is one of the staggering talents of our time.

Though he didn’t share any details about what the creative team has in store, the tease that The Martian fans should be excited for Project Hail Mary is some very good news.

Adding to the talent working behind the scenes of Project Hail Mary is Greig Fraser, the Academy Award-winning cinematographer from Dune, who serves as the director of photography, according to The Wrap.

On top of working with Denis Villeneuve on his acclaimed epic and its 2024 sequel, Fraser’s credits include movies like The Creator, The Batman, Rogue One, Zero Dark Thirty, Foxcatcher, and Lion. He’s also set to shoot Matt Reeves’ The Batman: Part II in the near future.

What Will Project Hail Mary Be Rated?

Amazon MGM Studios hasn’t said anything about the Project Hail Mary rating at this time, so for now, we can only speculate. Truth be told, a PG-13 rating seems like the best bet based on everything we’ve seen from the film. The 2015 adaptation of Andy Weir’s The Martian was rated PG-13 upon its release, and based on the tone and subject matter of the book, it seems just as likely that Project Hail Mary will aim for that as well.

With around six months between now and the Project Hail Mary release, now would be a perfect time to go back and revisit the last time one of Andy Weir’s novels hit the big screen. At the time of this writing, you can check out The Martian (for the first time or on a revisit) with a Netflix subscription. But if you want to own the movie, either digitally or on physical media, you can pick up a copy over at Amazon, where you can also buy all of Weir’s various sci-fi novels.

Expect to hear more about Project Hail Mary in the months leading up to its March 2026 debut. But that won’t be the only space adventure for Ryan Gosling in the next couple of years, as he is set to lead Shawn Levy’s Star Wars: Starfighter, one of the most anticipated upcoming Star Wars movies.

Philip grew up in Louisiana (not New Orleans) before moving to St. Louis after graduating from Louisiana State University-Shreveport. When he's not writing about movies or television, Philip can be found being chased by his three kids, telling his dogs to stop barking at the mailman, or chatting about professional wrestling to his wife. Writing gigs with school newspapers, multiple daily newspapers, and other varied job experiences led him to this point where he actually gets to write about movies, shows, wrestling, and documentaries (which is a huge win in his eyes). If the stars properly align, he will talk about For Love Of The Game being the best baseball movie of all time.
