The streaming launch comes as the studio gears up for an awards campaign, with the film already being tipped as a strong contender in categories such as Best Visual Effects and Adapted Screenplay.

Directed by the acclaimed duo Phil Lord and Christopher Miller, Project Hail Mary is adapted from Andy Weir’s bestselling novel, with a screenplay by Drew Goddard, who also adapted The Martian. Gosling stars as Ryland Grace, an ordinary science teacher who wakes up aboard a spacecraft with no memory of how he got there. As his memories slowly return, he realises he has been sent on humanity’s last mission, to stop a mysterious phenomenon that is causing the Sun to die and save Earth from extinction.
