If I told you that the most devastatingly beautiful friendship of the decade would be between a spider-rock alien and a sleep deprived schoolteacher, you’d probably not believe me. And then you’d read Project Hail Mary and cry your heart out. And then, you’d watch Project Hail Mary and cry your heart out again. Because that’s exactly what happened to me. When a friend recommended that I read the book back in 2022, and sobbed about the friendship between Rocky and Grace, I thought she was exaggerating. No one can top my Ann Perkins and Leslie Knope. At least that’s what I thought before I picked up the book 2 months ago.
Project Hail Mary is a sci-fi story about Grace, a schoolteacher who gets sent to space (I know, I know, bear with me) when humanity is on the verge of extinction because of the tiny little dots called astrophage. Whether you are a sci-fi fan or someone who thinks “hard science fiction” is equivalent to sitting for a thermodynamics exam, this story is for you.
Here’s everything you need to know about Project Hail Mary, the 2021 novel that stole hearts, and the 2026 film that has officially broken box office records and hearts in equal measure.
The book: A love letter to curiosity
Published in May 2021, Project Hail Mary follows Ryland Grace, a dorky middle-school teacher who wakes up alone on a spaceship 12 light years away from Earth. With no memory of who he is, what he’s supposed to do, or why his crewmates are all dead. As his memories gradually return, he figures out the terrifying reason for his foray into space travel. The Sun is dying. And it’s up to him to figure out the reason why before humanity freezes to extinction, along with most all other life on Earth.
The culprit are the micro-organisms known as astrophage, termed aptly for their star-eating habits. Stocked with his scientific training, a fully stocked lab full of… scientific things, and a relentless optimism, Grace must strive to save every living thing on planet Earth.
If you’re thinking the book will contain a lot of scientific wording and language and jargon… well you’re completely right, I won’t lie to you. But let me assure you, the way Andy Weir writes about the stuff is just fun. He has a gift for making complex science feel like the most exciting puzzle in the world. Grace narrates with a giddy enthusiasm of someone who loves learning and teaching, and his running internal monologue (“Wait. That’s how astrophage reproduces?!”) pulls you in whether or not you failed high school chemistry or not.
But the real turning point of the book comes about roughly halfway through, when Grace realises he’s not alone in the Tau Ceti solar system. We get introduced to the adorable, lovable hunk of rock, who Grace aptly names Rocky, and the rest is history.
Rocky and Grace cannot share air, cannot touch, and come from civilizations that have never before made contact. And yet they build a beautiful friendship through improvised sign language, the uniting power of mathematics, and the respect they both have for each other and each other’s cultures. Grace keeping watch over Rocky while he sleeps, and vice versa, because that is how Eridians feel safe enough to sleep will never make me not teary-eyed.
It won the Goodreads Choice Award for Best Science Fiction in 2021, was a finalist for the Hugo Award and it even wound up on both Barack Obama’s and Bill Gates’s reading lists. It’s a book made for the people, with its heartbreaking and emotional premise and an author who just genuinely loves science and dumbing it down for people like me.
THE THEMES: MORE THAN JUST THE SPACE STUFF
Don’t let the astrophysics intimidate you. At its core Project Hail Mary is a story about:
Science as a love language. The way Grace and Rocky communicate is through shared experiments and data. Their first conversations are literally math problems. And somehow, Weir makes this the most romantic (in the classical sense) courtship you’ve ever read. Knowledge is how they reach each other.
Friendship across difference. I’d wager Rocky and Grace are the most different people can be from each other, at least biologically. One is literally made of rocks, for heavens’ sake, with metal wires for a nervous system. But as different as they may be, their friendship just works. They lead with curiosity and empathy instead of letting fear dictate their actions. It’s a quiet, radical argument for empathy as the most powerful survival tool in the universe.
Sacrifice and what we owe each other. Without completely spoiling the book, the novel builds up to a moment of immense sacrifice that reframes everything you thought the book was about. What do you owe the strangers you’ll never meet? What do you owe the friend you love? There’re no easy answers for such existential questions. That’s what good fiction does, though. It makes you think; It makes you ask these questions.
PROJECT HAIL MARY – The Movie: Ryan Gosling In Space
The film adaptation has been in the works since 2020, when Ryan Gosling signed on to star in and produce the project before the novel had even been published. After years of anticipation, it finally hit theaters on March 20, 2026. And the response has been, to put it mildly, overwhelming.
Directed by Phil Lord and Christopher Miller, the film stars Gosling as Ryland Grace, our space-faring school teacher, and Sandra Hüller as Eva Stratt (my favourite character of all time). James Ortiz provides the voice and masterful puppeteering performance of Rocky.
It opened to $80.6 million in its debut weekend, which marked the biggest opening in Amazon MGM studios’ history. Since then, it has earned $517 million in global box office earnings (and counting), and an audience that keeps going back to watch it twice.
The movie has been lauded as Gosling’s best performance to date, with him being the only speaking character onscreen for more than half the runtime. To be able to carry the film only on the strength of his wit, physical comedy and vulnerability that makes Grace so memorable, is no easy task. To be able to accomplish it so well… Ryan Gosling deserves all the stars.
One scene in particular has stayed with me, even weeks after watching the movie for the first time.
The astrophage spacewalk. When Grace has to venture outside the Hail Mary while drifting through the Petrova line, he’s suddenly surrounded by swirling red points of light. The astrophage itself. Billions upon billions of micro-organisms floating in space, creating a scene so beautiful, it haunts my thoughts even now. It may not sound like much on paper, but the effect is genuinely breathtaking. Here’s the nerdy-wonderful detail: the filmmakers created it by placing tiny LEDs on chicken wire, pouring water in front of the lens to refract the light, and shooting it with a camera that had its infrared filter removed. The result looks like nothing else in recent cinema. Vast and delicate and somehow alive. It’s the most beautiful thing in a very beautiful film.
Should You Read the Book Before Watching the Movie?
Yes. A thousand times yes. Couldn’t recommend this enough. The movie is the most stunningly gorgeous piece of media in recent times, yes, but the book provides you with something the movie, by its nature, cannot. Time. The slow accumulation of Rocky and Grace’s friendship, the granular joy of watching Grace figure out each scientific puzzle, the particular ache of certain chapters. These live in the novel in a way that even a 156-minute film can’t fully replicate.
That said, the movie is genuinely wonderful, and if you’ve already seen it, the book will still reward you with depth and detail that will make you love the story even more.
Either way, Rocky is waiting. And he’s worth it.
(There’s a starman… waiting in the sky… )
