I had been waiting years for this film. I read "Project Hail Mary" by Andy Weir the moment it came out, back in 2021, and closed it with a feeling that few novels manage to give you: that of having witnessed something you did not know you needed until it was already inside you. The novel is extraordinary. And adaptations of extraordinary novels have a habit of breaking your heart.
Project Hail Mary did not break my heart. Quite the opposite.
The film, directed by Phil Lord and Christopher Miller, with Ryan Gosling as Ryland Grace, opened in Spain on 27 March 2026. I caught a preview screening and walked out doing something I almost never do: searching for the trailer to forward to someone with a simple "you have to see this". If you know the book, you already know why. And if you do not, this article tries to explain what makes this film so special.
First, the premise: what this actually is
Ryland Grace wakes up alone on a spaceship. He does not remember his name. He does not remember why he is there. Two corpses lie beside him. Through flashbacks that slowly restore his memory, the viewer pieces together the situation alongside him: the sun is dimming, devoured by microorganisms called astrophages. Humanity has years, not decades. And Grace is the last shot we have.
The film is written by Drew Goddard, the same screenwriter who adapted The Martian in 2015. That the very man who understood Mark Watney so well should return to bring Ryland Grace to the screen is no accident: it is the smartest decision the studio could have made.
What surprised me most: its faithfulness to the book
Screen adaptations of science fiction novels share a structural problem: science bores the executives. The first thing to vanish from the script is the technical explanations, the problem-solving processes, that whole chain of logic that is precisely what makes these stories special. The Martian (2015) showed it: a good film, but the science took a back seat to the spectacle.
Not here. Lord and Miller have understood that the science is not the obstacle to the story: it is the story. Watching Grace calculate, get it wrong, recalculate and build solutions out of whatever is on hand aboard a spaceship light-years from any help is as adrenaline-fuelled as any car chase. The viewer learns things while biting their nails. That is what Weir does on the page, and it is exactly what the film manages to carry onto the screen.
Ryan Gosling like you have never seen him
For years Gosling has been playing characters who hide something beneath a calm surface: the silent driver in Drive, Ken in Barbie, the replicant in Blade Runner 2049. Ryland Grace is different. He is a guy who thinks out loud, who chats to the ship, who celebrates his victories like a child and weeps over his failures without shame. He is the most expressive character Gosling has played in a long time, and you can tell he enjoyed every minute of it.
There is one scene in particular, the first time Grace realises who he is talking to, that without exaggeration is among the best things I have seen in a cinema in years. Just Gosling, a single reaction, and not a word of dialogue. Cinema as it should be.
And then there is Rocky
The character of Rocky, the alien Grace meets on his journey, was the biggest risk of the adaptation. In the book it works because Weir patiently builds up the logic of its communication, its biology, its way of seeing the world. On screen, at the pace the medium demands, that construction could easily collapse.
It does not collapse. James Ortiz provides the voice (with a stunning piece of sound design to reproduce the way Rocky speaks) and the visual effects team has created a creature design that is at once alien and entirely consistent with what the book describes. By the halfway mark you forget it is CGI. It is simply Rocky. And that is all you ever needed.
Phil Lord and Chris Miller out of their comfort zone
The directors of The LEGO Movie and Spider-Man: Into the Spider-Verse are masters of controlled chaos, of humour that does not interrupt the emotion but amplifies it. Project Hail Mary is the most ambitious film they have ever made, in scale and in tone, and at certain moments you can feel the tension between their playful instinct and the demands of the story.
But when it works —and it works for most of its 141 minutes— the combination is exactly what the material called for: science fiction that takes its science seriously yet never forgets that humour is a survival mechanism, not a concession to the audience.
Sandra Hüller, in her first major Hollywood role, gives us an Eva Stratt of pure, cold authority over a layer of humanity buried very deep. A restrained performance in a role that, in another actress hands, could have come out flat. Not here.
Is it really that faithful to the book?
There are changes. There always are, and those who know the book will spot them. Some of the flashback rhythms are compressed. The odd scientific explanation is simplified so as not to lose the teenage viewer who turns up having read nothing. There are a couple of narrative choices in the third act that the book resolves differently.
But the spirit is intact. The novel central question —what do we do when logic and science are all we have left— is in every single frame. And the ending, which was the adaptation biggest minefield, is handled with an honesty I did not expect from a production of this size.
Weir was present at the world premiere in London on 9 March. The author smiling in the premiere photos proves nothing, but it is hardly a bad sign either.
The numbers speak too
With 140.9 million dollars in its opening weekend worldwide —80.5 in the United States, a figure that beat every forecast— Project Hail Mary is the best Hollywood opening so far in 2026. On Rotten Tomatoes it tops 90% critical approval. On IMDb users rate it 8.6. SensaCine gives it 4.5 out of 5.
These numbers matter because they confirm something commercial cinema sometimes forgets: audiences want intelligent science fiction. Not just spectacle. They want characters who think, problems to solve, emotions that are earned. Weir knew it when he wrote the book. Lord and Miller have understood it in adapting it.
If the film has whetted your appetite for reading…
Before going back to Weir book —which you should read if you have not— you can explore a story that shares the same DNA: an ordinary guy trapped in an impossible setting, a programmer logic applied to survival, and black humour as his only shield. Except this time the void is the Namib Desert and the hero is you, hunting for signal so you can tweet.
PIZZA, TWITTER y 23 días en el INFIERNO →In conclusion: go and see it on the big screen
Project Hail Mary is one of those films that need the big room. Not because of the visual effects, excellent as they are. But because Grace solitude in space weighs heavier in the dark, the silence between two beings who share no language hits harder when the sound surrounds you, and the ending —that ending— deserves to be lived without a remote control within reach.
It is a rare film that sends you out of the cinema wanting to study physics. This one does. And on top of that it makes you cry over an alien that looks like a rock with legs. Not bad for 141 minutes on a Thursday in March.
One of the best science fiction films of the past decade. No smoke and no mirrors.
