Where was Supergirl filmed? That question has been spreading across fan communities ever since the first footage of DC’s highly anticipated 2026 blockbuster arrived. While Milly Alcock’s Supergirl delivers plenty of action, emotion and intergalactic chaos, many viewers have become just as fascinated by the spectacular landscapes and locations seen throughout the film. As with many major superhero productions, several filming details were kept tightly under wraps during production to avoid unwanted disruptions on set. Even so, enough information has emerged to paint a fascinating picture of where Craig Gillespie’s Supergirl brought its cosmic adventure to life.
The heart of production was Warner Bros. Studios Leavesden in Hertfordshire, England, a location that has quietly become one of the most important homes of blockbuster filmmaking. Huge portions of Supergirl were created inside its enormous soundstages, where entire worlds could be built from the ground up.
Production teams reportedly transformed sections of the studio into elements of Argo City and Kryptonian-inspired environments, complete with grand architecture, towering structures and intricate details that would be nearly impossible to create on location.
It is the sort of place where a simple warehouse door can hide an alien civilisation behind it. One minute you're standing in Hertfordshire, the next you're apparently millions of light-years from Earth.

The production also extended across other parts of Leavesden’s backlot facilities, where a classic American-style town was constructed. This setting plays an important role in grounding Kara’s story and maintaining her connection to Earth.
For British visitors, there is something amusing about watching a supposedly American town exist comfortably in the English countryside. Hollywood has been performing this trick for decades and audiences still happily fall for it every single time.
Not far from the studio base, filming activity also reached parts of London, where selected sequences benefited from the city's modern and historic visual contrasts. While specific streets were never heavily publicised, London’s versatility makes it a favourite destination for major productions.
The city can convincingly portray almost anywhere with the right camera angle. One street can look like a futuristic metropolis while the next resembles a period drama. It is essentially the acting superstar of filming locations.
Another location helping shape the film's distinctive visual identity was St Albans, which sits within easy reach of the main production hub.

The historic city offers centuries of architecture, open green spaces and cinematic surroundings that blend naturally with large-scale productions.
Its combination of heritage and accessibility has made it increasingly attractive for film crews looking for visually rich backdrops without venturing too far from London.
The film’s most breathtaking environments were captured in Iceland, where Supergirl’s interstellar journey truly comes alive. The country’s dramatic landscapes provided the perfect foundation for alien planets and distant worlds.
Vast black sand beaches, volcanic terrain and seemingly endless stretches of untouched wilderness helped create environments that look genuinely extraterrestrial. The beauty of Iceland is that filmmakers often need very little digital enhancement.
Nature has already done most of the work. If another planet exists that looks exactly like Iceland, scientists may want to start asking questions.

Among the standout Icelandic locations believed to contribute to the film's visual world-building is Reynisfjara Beach, famous for its black volcanic sands and striking coastal scenery.
Its surreal appearance has long attracted fantasy and science-fiction productions. Watching characters cross these landscapes feels less like visiting a real place and more like stepping directly into a graphic novel.
The production also utilised the broader South Iceland region, where lava fields, glaciers and rugged terrain create constantly changing scenery. These environments helped reinforce the harsh and unforgiving nature of the worlds Kara and Ruthye travel through during their quest.
Every frame appears designed to remind viewers that this is not a comfortable sightseeing holiday. It is an intergalactic revenge mission, and the scenery fully understands the assignment.
Scotland became another major piece of the Supergirl puzzle. The country's rugged mountains, remote valleys and expansive natural landscapes were used to create some of the film's most visually striking sequences.
Scotland's scenery already possesses an almost mythical quality, making it an ideal stand-in for distant worlds. Combined with digital effects, these locations evolved into colourful cosmic horizons inspired by the pages of Supergirl: Woman of Tomorrow.

Particular attention has focused on the Scottish Highlands, where sweeping mountain views and dramatic terrain added scale to the film's galactic adventure.
These landscapes helped create the sense that Kara and Ruthye are travelling across enormous worlds rather than simply crossing another movie set. It is difficult to fake that level of grandeur, which is exactly why filmmakers keep returning to Scotland whenever they need nature to show off a little.
Another Scottish location contributing to the film's atmosphere is Glen Coe, one of the country's most famous cinematic destinations. The valley's towering mountains and breathtaking scenery have appeared in numerous major productions over the years.
In Supergirl, locations like these help transform the journey into something far larger than a simple chase story, giving the adventure a genuine sense of scale and isolation.
Production on Supergirl officially began in January 2025 and wrapped in May 2025, allowing the team several months to capture footage across these diverse locations.
The combination of cutting-edge studio work and practical outdoor filming helped deliver the grounded yet fantastical visual style that fans of the comic series were hoping to see.

Fan reactions to the filming locations have been overwhelmingly varied. Many viewers have praised the decision to use real-world landscapes rather than relying entirely on computer-generated environments, arguing that Iceland and Scotland bring an authenticity that digital effects simply cannot replicate.
Others have been fascinated by the massive sets constructed at Leavesden, particularly after early production photos hinted at Kryptonian architecture.
Some fans have already begun discussing future travel plans inspired by the movie, while others are busy comparing screenshots frame by frame in an attempt to identify every mountain, beach and valley featured on screen.
As usual, the internet remains convinced it can solve every filmmaking mystery with enough determination and several cups of coffee. What is certain is that Supergirl has turned parts of England, Scotland and Iceland into destinations that many DC fans now want to experience for themselves.
From the vast soundstages of Warner Bros. Studios Leavesden to the volcanic landscapes of Iceland and the dramatic beauty of the Scottish Highlands, these locations helped shape one of DC’s most visually ambitious adventures.
