How 'Project Hail Mary' made Ryan Gosling's zero-G stunts look weightless

Variety reports that Gosling performed on wire rigs, including a rotating harness, because the elaborate spacecraft sets could not be recreated aboard a weightlessness flight. VFX artists removed the wires, adjusted his posture and added drifting objects to make him appear to float. The team also used European Space Agency star data to map the skies; co-supervisor Mag Sarnowska said half of Rocky's shots used puppets and half used CG.
