As book-to-screen adaptations go, Project Hail Mary already ranks up there with some of the best, in my opinion. Sure, Phil Lord and Christopher Miller's adaptation of Andy Weir's novel had to make some changes and leave a few things out, but overall, as a fan of the book, I loved the movie. I thought it did a good job of covering the necessary elements of the science-heavy story, while also leaving plenty of room for Ryan Gosling's character and his new pal Rocky to bond and figure out how to save their planets. There was one thing the 2026 movie didn't explain -- and to be fair, the book doesn't really either -- but it turns out, Andy Weir does know the answer... and he's not ready to tell us.
Spoilers from Project Hail Mary ahead!
