Hollywood loves green screens. Actors stand in front of glowing green walls, wave their arms dramatically, and pretend they are floating in space while a computer adds the galaxy later. But the upcoming film Project Hail Mary decided to take a completely different route. Directors Phil Lord and Christopher Miller made a bold choice. They filmed the entire movie without using a single green or blue screen. Yes, in a massive space movie. Chaos. Absolute madness. And somehow, it worked.
Instead of relying on traditional green screen techniques, the filmmakers built real sets, used practical effects, and combined them with advanced visual effects created later by studios like ILM and Framestore. The result aims to make the story feel more grounded, immersive, and believable.
Plot: A Teacher, A Spaceship, And Humanity’s Last Hope
The story comes from Andy Weir’s bestselling novel Project Hail Mary. If that name sounds familiar, it is because Weir also wrote The Martian, the book that turned Matt Damon into space’s most determined potato farmer. In this story, Ryan Gosling plays Ryland Grace, a middle school science teacher who suddenly wakes up alone on a spaceship far from Earth. He has no memory of who he is or why he is there. Not ideal when you are literally floating in deep space.
As his memory slowly returns, Grace realizes the terrifying truth. The sun is dying due to a mysterious cosmic phenomenon, and humanity faces extinction. His mission is to travel across the galaxy and find a solution that could save Earth. Along the way, Grace meets an unexpected companion named Rocky, an alien scientist from another world who is trying to save his own planet from the same cosmic disaster. Their unlikely friendship becomes the emotional core of the story. Think science puzzles, interstellar stakes, and a wholesome alien friendship. Basically, The Martian meets Interstellar with a buddy comedy twist. So how do you make such a movie without green screen?
How They Filmed Project Hail Mary Without Green Screens
Here is where the filmmaking gets really interesting. Instead of placing actors in front of green backgrounds, the production built the interior of the spaceship as a fully practical set. Cameras could move freely through the environment, and actors could interact with real objects instead of imaginary ones. They also built a large physical section of the spacecraft’s exterior for scenes set outside the ship. This allowed actors to physically stand on the hull rather than pretend to float in front of a screen.
When scenes required the emptiness of space, filmmakers shot actors against black or specially lit backgrounds. These setups created natural lighting on faces and suits, something green screens often struggle with. But let’s be clear. The film still contains a massive amount of digital work. It includes more than 2,000 visual effects shots, with ILM handling large-scale space environments and Framestore animating the alien Rocky. The difference is that the digital effects enhance real footage rather than replacing entire scenes.
Looks like Hollywood finally made a huge space movie without green screens. And honestly, that might be the most impressive “Hail Mary” play of all. Project Hail Mary is scheduled to hit theaters on March 20, 2026.
