Screenwriter Drew Goddard discusses the fate of Eva Stratt.
Like many book-to-film adaptations, Project Hail Mary alters some elements from its source material. Often, these changes involve removing parts of Andy Weir’s novel to streamline the movie. The film, for instance, omits the element of identifying astronauts with a rare coma resistance gene and the plan to cover the Sahara Desert in solar panels for energy. However, Project Hail Mary does introduce a new addition in its ending that deviates from the book.
The film concludes similarly to Weir’s novel, where Ryland Grace (Ryan Gosling) resides on alien Rocky’s planet, Erid, after sending the Hail Mary’s beetle probes back to Earth to help save the sun. Weir’s novel leaves the process of Grace’s research reaching Earth ambiguous, as the focus remains on Grace’s perspective throughout.
In contrast, the movie revisits Earth, depicting frozen oceans due to global cooling from the sun’s dimming and illustrates Stratt’s situation years post-launch of the Hail Mary. Unlike the book, which leaves Stratt’s fate unclear, suggesting she might end up in prison, the film portrays her as alive and ready to embark on the next phase of the mission.
Screenwriter Drew Goddard explained the decision to provide Stratt with an optimistic conclusion, emphasizing the importance of showing her character’s role in the story. “This movie is about a triangle between three characters,” he said. “It’s crucial to give her [Stratt] her moment.” The film offers a hopeful view of humanity’s recovery efforts.
Project Hail Mary is currently playing in theaters.
