In an era dominated by digital effects and virtual production, the filmmaking team behind the highly anticipated science fiction adaptation Project Hail Mary has taken a radically different approach. Directors Phil Lord and Christopher Miller have confirmed a groundbreaking technical achievement: the entire film was shot without using a single green or blue screen. This revelation, made during an interview with Comic Book, signals a significant return to large-scale practical filmmaking for a major studio space epic.
The Decision to Build Everything Practically
Adapting Andy Weir’s best-selling novel of the same name, which follows a lone astronaut on a desperate mission to save humanity, Lord and Miller faced the monumental task of visualizing interstellar travel, alien life, and the claustrophobic interior of a starship. Rather than relying on the now-standard practice of filming actors against blank screens to be filled in later with digital environments, the directors committed to constructing physical, tangible sets. “What’s fun about the movie is that there’s no green screen in the movie whatsoever,” Christopher Miller stated emphatically. “There’s not a single green or blue screen was used. The whole ship was built as a set from the inside.”
A Fully Realized Starship Interior
The centerpiece of this practical effort is the Hail Mary spacecraft itself. The production designed and built a complete, functional interior set where star Ryan Gosling, who plays astronaut Ryland Grace, could actually work and interact with his surroundings. Every console, panel, and corridor was a real, physical object. This allowed for a level of actor immersion and photographic authenticity that is difficult to achieve when performers must imagine their environment. Cinematographer Greig Fraser, the Oscar-winning director of photography behind Dune, leveraged this fully built set to employ practical lighting techniques, ensuring that the play of light and shadow within the metallic confines of the ship felt genuine and grounded in a real space.
Extending Practicality to the Exterior and Beyond
The commitment to realism did not stop at the ship’s hull. Miller revealed that the production went a step further, constructing a massive section of the spacecraft’s exterior on a backlot. “We had a huge section of the exterior of the ship that we built outside,” he explained. This enabled the filmmakers to shoot actual exterior scenes with realistic lighting conditions from the sun, rather than simulating everything in post-production. This approach echoes techniques from classic practical-effects-driven sci-fi films, where miniatures and large-scale models were the norm, but updates them with modern materials and scale.
Bringing an Alien to Life on Set
Perhaps the most challenging and innovative aspect of the no-green-screen mandate was the creation of Rocky, the alien entity that becomes central to the story. In the novel, Rocky is a truly alien lifeform with a unique biology and form of communication. Instead of having Gosling perform to a tennis ball on a stick or an empty space for a CGI character to be added later, the production created a physical, on-set model of Rocky.
The Benefits of a Physical Co-Star
This decision had profound implications for the performance and the film’s authenticity. “Rocky was really with us the whole time,” Miller said. “That’s what makes everything feel real and natural.” For Ryan Gosling, this meant he had a tangible presence to react to and interact with during scenes. An actor’s eyeline, physical timing, and emotional response are fundamentally different when they are sharing the space with something real. The physical model served as a precise reference for the visual effects team, who later enhanced it with computer graphics to achieve the final, fully realized alien. This hybrid method—starting with a practical foundation and augmenting it digitally—is often cited as the key to the enduring believability of creatures in films like Jurassic Park.
The Cinematic Philosophy Behind the Choice
The move away from green screens is not merely a technical flex but a deliberate philosophical choice by Lord and Miller. Green screen, while incredibly powerful and flexible, can create a disconnect between the actor and their environment. Lighting can become a complex negotiation between the practical set and the digital world to be added, and performances can suffer from a lack of physical context. By building the sets for real, the directors ensured that every element captured by the camera—from the reflections on a console to the way light spills into a corridor—was organically generated on the day of filming. This results in a cohesive, immersive visual language that audiences subconsciously register as more authentic.
Greig Fraser’s Role in Grounding the Fantasy
The involvement of Greig Fraser was pivotal. Known for his work on Dune and Rogue One, Fraser is a master of creating vast, believable worlds. On Project Hail Mary, his task was to light a real spaceship as if it were in the void of space. Using complex arrays of practical LEDs and traditional lighting units, he could simulate the harsh, direct light of a nearby star or the eerie glow of control panels in the darkness. This in-camera approach gives the visual effects artists a perfect, photorealistic base to work from, rather than having to create all lighting and atmosphere from scratch in a computer.
Industry Context and a Potential Trend Shift
This production model stands in stark contrast to the prevailing trends in blockbuster filmmaking, especially for science fiction and superhero genres, which have increasingly moved toward virtual production using technologies like LED volumes (popularized by The Mandalorian). While those technologies offer their own advantages, Lord and Miller’s approach is a deliberate throwback to a more tactile era. It represents a significant financial and logistical gamble for a studio, as building massive practical sets is often more costly upfront than planning for digital augmentation. However, the potential payoff is a distinctive visual texture and a performance-driven authenticity that can set a film apart in a crowded marketplace.
Screenwriter Drew Goddard’s Foundation
The film’s commitment to tangible reality is supported by its script, penned by Drew Goddard (The Martian, Cabin in the Woods). Goddard has experience with scientifically-grounded storytelling, having written the screenplay for The Martian, another Andy Weir adaptation. His script for Project Hail Mary likely emphasized the problem-solving, procedural, and isolated nature of the story, elements that are enhanced by shooting in a real, confined environment that the actor can physically explore and manipulate.
Audience and Critical Expectations
With the film’s release confirmed for March, audiences and critics will be scrutinizing the results of this ambitious methodology. The promise of a green-screen-free space adventure has certainly raised expectations for a visceral and immersive cinematic experience. The success of this approach could influence directorial choices on future large-scale projects, prompting a renewed appreciation for the art of physical set design and in-camera effects, even as digital tools grow more sophisticated.
The ultimate testament to the success of Project Hail Mary‘s production philosophy will be felt in the theater. When Ryan Gosling’s character floats in zero-gravity within his ship or communicates with the alien Rocky, the audience’s belief in the moment will hinge on the subtle, accumulated realism of a world that was actually built, lit, and performed within. In prioritizing the actor’s environment and the cinematographer’s light, Phil Lord, Christopher Miller, and their team have bet that the oldest tricks in the filmmaking book—building sets and using props—remain the most powerful tools for making the impossible feel palpably, thrillingly real.
