First, in the plainest language, before we get to anything else, Project Hail Mary is a fantastic film. It does right by its source material, and it also easily stands on its own for folks who haven’t read the book. It comes out on March 20, and if you’re a regular Ars Technica reader, you will almost certainly enjoy the crap out of it. Go see it as soon as you can, and see it in a theater where the big visuals will have the most impact.
Next, a word about what “spoiler-free” means here: In this short review, I’ll talk about stuff that happens in the movie’s many, many trailers. If you’re an ultra-purist who is both interested in this film and who has also somehow avoided reading the book and also seeing any of the trailers, bail out now.
Otherwise, read on!
It’s a buddy movie
PHM is, first and foremost, a movie about a schoolteacher who becomes friends with an alien and the joy of that relationship. And because the film is based on an Andy Weir novel, there’s also some problem-solving with science.
What problems? A pretty major one dominates: As we learned back in the first trailer, the Earth’s sun is mysteriously dying, and no one knows why. An assay of our nearby stellar neighbors reveals that those stars all appear to be dying as well—all except for one, Tau Ceti, located just under a dozen light-years away. Why is Tau Ceti seemingly being spared by whatever force is causing the other stars to dim? In what quickly becomes a common refrain, no one knows.

The solution, as presented to us by a mysterious government representative named Eva Stratt (Sandra Hüller), is to build an interstellar craft, accelerate it to near the speed of light, and visit Tau Ceti to find out what’s going on. It’s a long-shot mission—a “Hail Mary,” as she puts it.
