'Project Hail Mary': Release date, plot, cast, and everything we know about Ryan Gosling's mission to save the world

Ryan Gosling upside down floating in zero gravity in Project Hail Mary (2026).

"Project Hail Mary" is the next major Hollywood blockbuster to be adapted from the works of 'The Martian' author Andy Weir, and this time it's Ryan Gosling's turn to "science the s**t" out of another cosmic conundrum. In this big-screen adaptation of his hit 2021 novel, however, the problem at hand is rather bigger than getting a stranded astronaut home from Mars.

A faltering Sun means that Earth is facing the extinction-level event to end them all, and the planet's hope is a school teacher sent on an interstellar mission with extremely low odds of success. Luckily, Dr Ryland Grace is played by Ryan Gosling — a man with plenty of experience in movie heroics — and he'll have an unlikely sidekick in the form of a bizarre five-legged alien named Rocky.
