The trick of Project Hail Mary isn't the science, though there's plenty of it, correctly and lovingly rendered. It's the structure: a man wakes up in a room designed like a hospital, two coffins holding dead strangers beside him, no memory of his own name, and a slow, methodical unspooling of how he got there. Lord and Miller, better known for cartoon anarchy, direct this like they've been saving up patience for years.
The film keeps cutting back to a classroom on Earth, and it's there, not in the void, that it finds its actual subject.
Ryan Gosling plays Ryland Grace as a man built entirely out of second-guessing himself, which turns out to be the correct instinct for a story this improbable. The cockpit sequences, all switches and readouts and gravity that isn't quite Earth's, have the tactile, overexplained joy of a film that wants you to understand exactly how everything works before it breaks your heart with it.
The flashback structure does a lot of quiet work. Every time the film returns to Grace's classroom, checkered-flag t-shirt and all, holding up a beanbag to make a point about mass, it's recalibrating what the mission is actually for. It's a strange choice for a first-contact movie to keep circling back to a middle school, and it's the reason the ending lands as hard as it does.
It isn't a perfect ascent. The film's opening stretch, all disorientation and exposition, asks for more patience than it's earned yet, and a couple of the science-fair-adjacent problem-solving detours run a beat longer than they need to. But by the time the mission's true shape reveals itself, those early inefficiencies read less like flaws and more like a movie that knew exactly how much rope it needed before the swing.
