We finally know the story behind the famous Ryland Grace Polaroid photo!
In a recent thread, Project Hail Mary director Christopher Miller shared new behind-the-scenes photos and revealed that the image used in the movie was actually a Photoshop composite of two phone photos he took during production, later adjusted to look more like a real Polaroid.
Ryan Gosling was holding a blank Polaroid on set. The final image was integrated into the movie by the VFX team.
