With the introduction of Superman and the second season of Peacemaker, the new DC Cinematic Universe (DCU) crafted by James Gunn is beginning to take shape, establishing a foundation of gods and monsters. This burgeoning universe will soon expand with the upcoming film, Supergirl, set to release in July 2025.
Historically, Supergirl, the character also known as Kara Zor-El, has had her ups and downs in live-action formats. Her first feature film, released in 1984 with Helen Slater in the titular role, failed to achieve significant box office success, which hindered any potential for a dedicated series. Slater later reprised a role in The CW’s Supergirl series, showcasing the character’s ability to coexist alongside other prominent DC superheroes.
Gunn’s approach to Supergirl promises a unique twist. Unlike previous adaptations, this film will explore a darker, more complex version of Kara, drawing inspiration from the 2021 comic series Supergirl: Woman of Tomorrow by Tom King and illustrated by Bilquis Evely. The narrative, which takes place in space, presents a resentful Kara who struggles with her place in the universe.
In the source material, Kara embarks on an emotional journey alongside a young alien, Ruthye Marye Knoll, who seeks vengeance against Krem, the antagonist responsible for her father’s death. This quest leads Kara through various alien worlds and challenges, encouraging her to confront notions of vengeance and morality.
The film adaptation will retain much of the essence of Woman of Tomorrow, though it will include some modifications. The movie opens with Kara and her dog, Krypto, celebrating her 23rd birthday on an unknown alien planet. Their peaceful moment is disrupted when Ruthye approaches with her request for assistance, leading to a series of thrilling encounters, including a bar fight.
Fans can expect a vividly detailed universe that allows for exploration of multiple interstellar settings, each with unique challenges and societies. The film will maintain its cosmic focus, introducing at least six different alien worlds, while also hinting at visits back to Kara’s home, Argo City, as well as possibly other familiar locations within the DCU.
Milly Alcock has been cast as Kara Zor-El, bringing a fresh perspective to the character. The actress, known for her role as a young Rhaenyra Targaryen in House of the Dragon, perfectly embodies a Kara defined by her complex emotional scars. Her juxtaposition with Clark Kent’s more hopeful view on humanity creates a narrative tension that promises depth.
The film will also feature Matthias Schoenaerts as Krem, whose motivations will reveal a nuanced antagonist battling personal demons. Eve Ridley plays Ruthye Marye Knoll, whose character will serve as a vital narrative element, possibly transforming through the storytelling arc.
Moreover, Jason Momoa is set to make a special appearance as Lobo, an unconventional and chaotic ally within the universe. His cameo may tie back to the overarching DCU narrative, though details remain sparse.
Taking the director’s chair is Craig Gillespie, known for his work on I, Tonya and Cruella, signaling a focus on character-driven storytelling. The film’s production team consists of seasoned professionals behind the lens, including cinematographer Rob Hardy and editor Tatiana S. Riegel, among others.
Filming commenced in January 2025 and took place across several locations, including London and Scotland, emphasizing an extensive production effort to bring the vibrant worlds of Supergirl to life.
As the DCU expands with Supergirl, fans eagerly anticipate how this fresh interpretation of the beloved character will resonate with audiences. With a release date set for July 26, 2025, excitement continues to build around Kara’s remarkable journey through the cosmos and her evolution into a more complex hero.
