A cape can carry many things, but expectation has rarely looked this heavy. Milly Alcock arrives as Supergirl with audiences already watching her every move after her Superman introduction, while Craig Gillespie's adaptation of Tom King's Woman of Tomorrow promises a Kara Zor-El shaped more by vengeance than virtue. Early reactions have singled out Alcock's commanding performance, suggesting that the heroine has traded sweetness for steel.

One of the film's biggest departures is its setting. Rather than staying rooted on Earth or Krypton, Supergirl ventures across multiple cosmic worlds, making its filming locations every bit as fascinating as the adventure itself.

Most of Supergirl was filmed at Warner Bros. Studios Leavesden in Hertfordshire, where the DC Universe traded familiar skylines for distant galaxies. Production ran from January to May 2025, with the studio serving as the film's creative backbone. Practical sets worked alongside advanced virtual production technology, allowing the crew to craft an expansive cosmic adventure without relying on a single filmmaking approach.

One of the production's standout achievements was the construction of Evely, a war-ravaged town on the planet Bilquis. Rather than a polished science-fiction city, the set featured crumbling buildings, scattered rubble, and burned-out vehicles, reflecting a world left vulnerable to pirate raids. The detailed environment gave the cast a tangible setting that matched the story's darker tone.

Beyond the studio, filming also took place in London, Scotland, and Iceland. Scotland's rugged landscapes provided convincing stand-ins for remote alien worlds, while Iceland's striking volcanic terrain expanded the film's otherworldly scale during the final stretch of production. London also hosted on-location filming, complementing the extensive work completed at Leavesden.

Why Supergirl and Not Superwoman? The Real Reason Why Superman’s Cousin Never Takes the Grown-Up Name

While audiences speculate about Supergirl's bisexuality and her galaxy-spanning adventure, the film's remarkable settings deserve plenty of attention too.

Forget another trip through Metropolis. According to Woman of Tomorrow, Supergirl sends Kara Zor-El across a bruised and breathtaking corner of the galaxy, where every stop feels stranger than the last. Raised on the dying remains of Argo City instead of a peaceful Kansas farm, Kara begins her journey carrying scars that shape every destination she visits.

The adventure quickly expands into a cosmic road trip. Kara crosses an intergalactic bus stop buzzing with bounty hunters, travelers, and outlaws before joining Ruthye on a revenge quest spanning five distinct alien worlds. Along the way, ancient ruins, unfamiliar civilizations, and harsh frontiers replace the comfortable superhero scenery audiences have come to expect.

One unforgettable detour takes Kara to a planet orbiting a red sun, where her Kryptonian abilities disappear and she briefly experiences ordinary vulnerability. The galaxy itself becomes as important as its heroine, making the remarkable filming locations all the more fascinating to discover behind the fantasy.
