What Will Happen in Project Hail Mary?
Warning - The following contains spoilers for the Project Hail Mary novel.
It's safe to assume that Project Hail Mary's general plot will mirror that of the novel, similar to the film adaptation of The Martian (which did make a few changes).
While it's best to go in blind to the story of Project Hail Mary, here's an idea of what happens to Ryland Grace (teacher, scientist, and astronaut).
Project Hail Mary follows Ryland, the sole survivor of a critical mission ("Project Hail Mary") to save humanity and Earth. He wakes up on a spacecraft floating through the cosmos with no memory of his identity or mission.
One of the more gripping elements of Project Hail Mary is that it's all from Ryland's perspective, so flash-back scenes are read the first time while he "remembers" them in real-time.
This back-and-forth storytelling will hopefully be an element of the movie as it shows the audience Ryland's immediate reactions to critical moments of the past, putting the pieces together of why he's there.
Many readers will be excited to see Ryland's unexpected ally visualized for the big screen and to learn whether Project Hail Mary will ultimately be a success or failure.
Project Hail Mary blasts into theaters on March 20, 2026.
