Hollywood's next sci-fi blockbuster, Project Hail Mary, is bringing its interstellar drama to Earth — specifically to the UK. New reports have revealed that the 2026 film shot key scenes across Cambridgeshire, Dorset, Hertfordshire, and Hampshire, turning these scenic counties into alien worlds and high-tech laboratories.

UK Counties Double as Alien Landscapes

According to The Worldwide Guide To Movie Locations, the production scouted multiple English locations to bring Andy Weir's bestselling novel to life. The choice of these diverse regions highlights the film's need for both sprawling natural backdrops and controlled, futuristic interiors.

Cambridgeshire, known for its flat fenlands and historic architecture, likely provides the vast, open spaces that can be digitally transformed into extraterrestrial vistas. Dorset's rugged Jurassic Coast, with its dramatic cliffs and rock formations, offers a prime canvas for alien terrain. Hampshire and Hertfordshire, meanwhile, are home to well-established studio facilities and stately homes that can be adapted for the film's spacecraft and research settings.

Location Breakdown

  • Cambridgeshire: Fenland landscapes and university architecture.
  • Dorset: Coastal cliffs and geological formations.
  • Hertfordshire: Studio space and rural countryside.
  • Hampshire: Historical estates and modern facilities.

From Page to Screen: The Sci-Fi Adaptation

Project Hail Mary, based on the acclaimed novel by Andy Weir (author of The Martian), follows a lone astronaut who wakes up with amnesia on a spaceship and must piece together his mission to save Earth. The story is a blend of hard science, survival, and unexpected camaraderie, making it one of the most anticipated sci-fi releases of 2026.

Filming in the UK has become a staple for major productions, thanks to generous tax incentives and world-class crews. The choice to shoot across four different counties suggests a varied visual palette, with each location serving a distinct narrative purpose. For fans of the book, seeing these real-world spots on screen will add a layer of authenticity to the futuristic tale.

Why These Locations?

The production team likely selected these areas for their versatility. Dorset's coastline can be made to look desolate and otherworldly, while Cambridgeshire's flat horizons evoke a sense of isolation. Hertfordshire and Hampshire offer logistical convenience, with studios and transport links that streamline the complex shoot.

Moreover, using real locations rather than purely green-screen sets helps actors deliver grounded performances, and audiences can feel the tangible weight of the environments. This approach has become a hallmark of modern sci-fi, blending practical effects with CGI to create immersive worlds.

What to Expect from the Film

While specific plot details remain under wraps, the casting and crew have generated significant buzz. The film aims to capture the novel's mix of tension, humor, and scientific wonder. With such a rich source material, the visual storytelling will be crucial to conveying the protagonist's journey.

The use of UK locations also signals a strong commitment to practical filmmaking, which often translates to more impressive action sequences and believable spaceship interiors. Fans can look forward to seeing familiar British landscapes transformed into the far reaches of the galaxy.

As the release date approaches, more details about the production are likely to emerge. For now, location scouts and film enthusiasts can start planning their own tours of these filming sites, from the pebbled beaches of Dorset to the quiet lanes of Hertfordshire.
