Who plays Eva Stratt in Project Hail Mary?

Sandra Hüller plays Eva Stratt in Project Hail Mary. Stratt is the formidable administrator who assembles and directs the international response to the astrophage crisis, making her one of the story’s key Earth-based figures.

Hüller is a German actress whose international profile expanded sharply after starring in Anatomy of a Fall (2023), for which she received major awards attention. Her casting placed a prominent European performer in the role of the multilingual, politically powerful scientist-administrator.

A common mix-up is confusing Eva Stratt with Ryland Grace, the film’s central astronaut, played by Ryan Gosling. Stratt is not the mission’s pilot or the story’s narrator; she is the organizer who helps make the mission possible. The film adapts Andy Weir’s 2021 science-fiction novel and was directed by Phil Lord and Christopher Miller.
