- Ryan Gosling performed his own zero-G stunts on wire rigs — including a rotating harness — after the team failed to convince production to use a "vomit comet" aircraft, whose cabin couldn't accommodate the film's elaborate spacecraft sets.
- Paul Lambert and Mag Sarnowska mapped the film's star fields using data from the European Space Agency's Gaia mission, charting the path between Earth and Tau Ceti (11.9 light-years away) and choosing to keep skies realistic rather than fill them with colorful nebulae.
- After removing the wires, VFX artists still found Gosling appearing to hang rather than float; they adjusted the position of his arms, legs or torso and added drifting objects to reinforce the weightless illusion.
- DP Greig Fraser shot Earth footage on Kodak 5254 with silver retention for a subdued look and grainier 5203 for space, and returned during postproduction with ILM's Helios virtual-camera system to reposition shots near planet Adrian without losing Gosling's original performance.
- Rocky was performed physically by James Ortiz and a puppeteer team across three practical versions (animatronic and a smaller reference puppet); Framestore scanned the creation so CG Rocky could mimic the puppeteers when cramped sets made live operation impossible — internal reviewers sometimes could not tell the versions apart.
- For Rocky's sonar-style POV, the team printed imagery onto 10mm and 16mm film formats for a more organic texture distinct from the movie's main digital capture.
Why it matters: The VFX on 'Project Hail Mary' leaned heavily on practical anchors — Gosling's wire stunts, Fraser's matched Kodak stocks, and three Rocky puppets — while layering digital tools like Gaia star-field data and ILM's Helios to manage what cameras could not capture. Roughly half of Rocky's shots stayed as physical puppetry, a split that shows how prestige sci-fi now blends analog craft with invisible CG rather than choosing one over the other.
