When and where to watch Project Hail Mary
Project Hail Mary is slated to premiere on Prime Video and will begin streaming on July 3, 2026. The official announcement was shared on the film’s social media handle, which posted a clip from the Ryan Gosling starrer.
Project Hail Mary follows Ryland Grace, a former molecular biologist and middle school teacher who wakes up aboard the spacecraft Hail Mary with no memory of how he got there. As his memories gradually return, he learns that he is on a crucial mission to the Tau Ceti system after a mysterious microorganism begins reducing the Sun’s energy output, putting Earth’s future at risk.
Through flashbacks, Grace recalls being recruited by Eva Stratt to join Project Hail Mary, an international effort to study the organism known as astrophage and find a solution. After helping develop the mission and its unique fuel source, Grace unexpectedly becomes the sole surviving crew member on the journey.
While exploring the Tau Ceti system, Grace encounters Rocky, an alien engineer from the planet Erid who is on a similar mission to save his own world. Despite their vastly different biology and methods of communication, the two form an unlikely friendship and combine their knowledge to study an organism capable of controlling the spread of astrophage.
Working together, Grace and Rocky develop a solution that could save both civilizations. However, an unexpected complication during their return journey forces Grace to make a life-changing decision between returning to Earth and ensuring Rocky’s people have a future.
In the end, Grace sends the solution back to Earth before choosing to remain on Erid, where he begins a new chapter of his life by teaching science to the planet’s children while awaiting the possibility of one day returning home.
