I’ve been thinking about something this week. Andy Weir might actually be one of the hardest modern authors to adapt.
And it’s not because the science is complicated. It’s because of where his tension lives.
Most stories build suspense through conflict between characters. Weir builds suspense through problem-solving. The question usually isn’t will the villain win. It’s will this solution work? That’s a different kind of drama. A very unique kind of tension.
It works beautifully in a novel. It is surprisingly hard to put on screen.
Project Hail Mary is about to hit theaters, early reactions are glowing, and critics seem to absolutely love it. That can be a good sign, especially for movies like this. But critics liking a movie isn’t the question I’m interested in yet. The question I’m interested in is structural.
Why is Andy Weir so difficult to adapt in the first place? Because if we don’t understand the problem he creates for filmmakers, we’re not really going to understand what this movie has to solve.
The Engineering Loop
The best way I’ve found to describe Weir’s storytelling is that it runs on procedural thinking. His books are basically engineering logs disguised as thrillers.
Most stories run on conflict between characters. Weir stories run on a loop. There’s a problem. The character has to calculate a solution. They try the solution. Something breaks. Now there’s a new problem.
The tension lives in whether the math holds under that kind of pressure, and then in whatever the next solution turns out to be.
On the page, that is fantastic. It’s addictive. But notice what it requires: the reader has to participate. You’re solving it alongside the character. You’re tracking oxygen, food, distance, time. Your brain is engaged in the process.
Movies don’t work that way.
Movies can’t show you a calculation happening inside someone’s head, at least not convincingly. They show behavior. They show consequences. So right away you’ve got a translation problem. What replaces the internal calculation? What replaces the reader’s participation?
Because if the movie just explains the science, you’re not building tension. You’re doing expository work. You’re building distance. An explanation isn’t drama.
Where the Trap Is
From a filmmaking standpoint, that’s where the trap sits.
Math is invisible on screen. Iteration chews up pacing. And long explanations kill scene momentum.
So the moment you adapt a story where thinking is the battlefield, you have to invent a cinematic replacement for that thinking. And this is where the real craft problems start showing up.
If you’re the screenwriter or the director adapting Andy Weir, the question isn’t how do I keep the science accurate. The questions are: how do I visualize thinking? How do I compress trial and error without losing tension? How much technical dialogue can an audience actually track in real time before they check out?
Because novels recruit your brain first. Movies recruit your nervous system first. That’s just how the medium works.
And Weir leans heavily on the cerebral. He leans hard into your brain. So unless you translate that cognitive tension into something visible, your adaptation is going to stall.
The Martian Solved It Once
We have seen this translation succeed. The Martian.
I’m not breaking that film down here, that’s a whole other video. I’m using it as proof that the problem can be solved.
What that movie figured out was a translation trick. Instead of making the audience watch calculations, it made the audience watch attempts. Every solution created a new situation. Every fix produced a new crisis. So even if you didn’t understand the chemistry or the engineering, you could still track the stakes. If this works, he survives. If he fails, he doesn’t.
The movie turned problem-solving into visible effort. That’s what kept the tension alive.
But that raises the bigger question. Was The Martian a blueprint, or was it a one-time solution?
In other words, did that movie discover the cinematic language for Andy Weir storytelling, or did it just find one way to make that specific story work? Those are very different things.
If it’s a blueprint, the next adaptation should be able to use a similar engine. If it was a one-off, then every new Andy Weir movie has to reinvent the approach from scratch.
Why Hail Mary Is the Harder Version
And that’s where Project Hail Mary becomes genuinely interesting.
Structurally, that story is an even harder adaptation problem. The cognitive load is much heavier. The storytelling mechanics are more delicate. Which means the filmmakers have to solve the same translation problem again, but under more pressure.
Critics saying the movie works doesn’t tell us how that problem was solved. It just tells us the movie works. Those are two very different conversations.
I’ll admit something here. I actually saw The Martian before I ever read the book. The movie hooked me emotionally first. Only later did I really appreciate how impressive the engineering problem-solving was.
Which should tell you something interesting about how cinema works. The film solved the emotional problem before it solved the intellectual one. That’s the order movies usually have to follow. If the audience doesn’t care first, the cleverness doesn’t matter. Period.
What I’m Actually Watching For
So when I walk into Project Hail Mary, I’m not just watching the science. That’s going to be there, obviously. I’m watching for something more specific.
Did the filmmakers invent a new cinematic way to translate Weir’s procedural storytelling, or did they reuse the grammar that made The Martian work?
And more importantly: does the movie solve the emotional problem before it starts asking me to admire the intellectual one?
Because if the science ever becomes more impressive than it is personal, you’re not inside the story anymore. You’re watching it from a distance. And that’s where these adaptations start to break.
So there you go. Now you know. And if knowing is half the battle, you’re halfway to being a know-it-all yourself.
Andy Weir writes stories where the protagonist’s mind is the battlefield. Cinema isn’t naturally built for that grammar, so every adaptation has to invent a way to turn thinking into tension. The Martian found one way to do it, and I’d argue it did it very successfully. The real question is whether Project Hail Mary found another.
That’s what we’re about to find out.
When you walk into this one, what are you looking for? The science, the spectacle, or whether the movie makes the problem-solving feel human? And if you want a full retrospective breakdown of The Martian now that this channel exists, say so in the comments on the video above.
