The much-anticipated sci-fi film Project Hail Mary is out in theaters today. In it, light-eating alien microbes sap the sun’s energy, threatening life on Earth with extinction. To find a solution, an unlikely hero—a middle school teacher played by Ryan Gosling—is sent on a one-way mission to the star Tau Ceti and encounters an otherworldly sidekick nicknamed Rocky along the way.

Ryan Gosling is irresistible in Project Hail Mary.

Gosling plays Ryland Grace, a middle school science teacher who we first see waking up alone on a spaceship, with absolutely no memory of how he ended up light-years from home.
