Adapts Project Hail Mary by Andy Weir. Say how far you watched, and pick the book up exactly there.
at Project Hail Mary.
The film adapts Weir's standalone novel start to finish in one pass, condensing the science and moving faster through the amnesia-driven mystery that the book takes its time unraveling. The last scene is also reframed for the screen, on the filmmakers' own account — worth reading the novel for its own version rather than assuming the movie already told you how it ends.

What the movies changed here
- CutMuch of the book's step-by-step scientific problem-solving — aboard the ship and in the Earth-side flashbacks — is condensed for runtime.
- ChangedGrace pieces together who and where he is much faster on screen; the novel spends longer inside his amnesia and the flashbacks that resolve it.
- ChangedThe final scene is reframed for the film — a question the novel resolves outright is left more open on screen, a choice the filmmakers have spoken about directly.
Lord and Miller's 2026 film is a faithful, single-pass adaptation of Andy Weir's standalone 2021 novel — same story, same structure, same overall shape — condensing its science-heavy problem-solving for runtime. The one deliberate departure is the very last scene, which the filmmakers have said they reframed on purpose.
Rate it from where you are. No account, and nothing here says a word about what happens next.
