While Gunn has assembled some of the most memorable and beloved ensembles in recent superhero cinema, his latest statement suggests that Alcock’s portrayal of Kara Zor-El is something truly special. “She might be the best bit of casting I’ve ever done in my entire life,” Gunn shared with Stern, adding, “I think she’s absolutely stunning in the movie.” This is a significant endorsement from a filmmaker who has a proven track record of identifying and nurturing talent.
From Westeros to Metropolis: The Rise of Milly Alcock
For many, Milly Alcock is best known for her breakout role as the young Princess Rhaenyra Targaryen in HBO’s critically acclaimed Game of Thrones prequel, House of the Dragon. Her powerful and nuanced performance in the series garnered widespread praise and established her as a rising star to watch. Now, Alcock is set to trade dragons for a cape as she takes on the iconic role of Supergirl in the new DC Universe.

Alcock’s casting as Supergirl was first announced in January 2024, and fans have been eagerly anticipating her debut in the DCU. While she made a brief, uncredited appearance at the end of this summer’s Superman, her standalone film, Supergirl: Woman of Tomorrow, is slated for release on June 26, 2026. The film is based on the critically acclaimed comic book series of the same name by Tom King and Bilquis Evely, which promises a more mature and complex take on the character.
A New Kind of Supergirl for a New DCU
James Gunn’s excitement for Alcock’s performance is a strong indication that Supergirl: Woman of Tomorrow will be a cornerstone of the new DCU. The film, directed by Craig Gillespie (Cruella, I, Tonya), is expected to offer a fresh and compelling take on the character, moving away from some of the more traditional portrayals of the Girl of Steel. The source material, Supergirl: Woman of Tomorrow, is a dark and introspective space western that sees a jaded Supergirl team up with a young alien girl seeking revenge. If the film follows the comic’s lead, we can expect a Supergirl who is more world-weary and complex than we’ve seen on screen before.

The film boasts an impressive cast alongside Alcock, including Matthias Schoenaerts as Krem of the Yellow Hills, Eve Ridley as Ruthye Marye Knoll, David Krumholtz as Zor-El, Emily Beecham as Alura In-Ze, and a surprise appearance by Jason Momoa as the intergalactic bounty hunter Lobo. This eclectic mix of characters suggests a film that will be as epic in scope as it is emotionally resonant.
What This Means for the DCU
Gunn’s high praise for Alcock is more than just a simple compliment; it’s a statement of intent. By singling out Alcock’s performance, Gunn is signaling that the new DCU will be built on a foundation of strong, character-driven storytelling. His emphasis on casting and performance suggests a commitment to bringing a new level of depth and artistry to the superhero genre. As the DCU continues to take shape, it’s clear that James Gunn and Peter Safran are playing the long game, and with talents like Milly Alcock leading the charge, the future of the DCU looks brighter than ever.
James Gunn’s Track Record: Why His Praise Matters
When James Gunn declares something to be his “best casting choice ever,” it carries significant weight. Throughout his career, Gunn has demonstrated an exceptional ability to identify and develop talent, often casting actors who go on to become fan favorites and critical darlings. His work on the Guardians of the Galaxy trilogy transformed relatively unknown actors like Chris Pratt, Zoe Saldana, and Dave Bautista into household names and beloved characters.
In The Suicide Squad, Gunn’s casting choices were equally inspired. He took risks with actors like John Cena, who delivered a breakout performance as Peacemaker, and Margot Robbie, who became the definitive Harley Quinn. Gunn’s ability to see potential in actors and bring out their best performances has been a hallmark of his directorial style.

Given this track record, Gunn’s praise for Alcock is particularly noteworthy. It suggests that her performance as Supergirl will not only meet expectations but exceed them in ways that even seasoned industry professionals find remarkable. This level of confidence from Gunn bodes well for both Alcock’s career and the future of the DCU.
The Importance of Supergirl in the DCU
Supergirl has always been a crucial character in the DC Comics universe, but her role in the new DCU appears to be even more significant. As one of the few female-led superhero films in the initial slate of DCU projects, Supergirl: Woman of Tomorrow carries the weight of representation and the responsibility of establishing a strong female presence in the new cinematic universe.
The character of Supergirl, or Kara Zor-El, has a rich history in comics, television, and film. From her debut in Action Comics #252 in 1959 to her recent appearances in various media, Supergirl has evolved from Superman’s younger cousin to a fully realized hero in her own right. The Woman of Tomorrow storyline, in particular, presents Supergirl as a seasoned and complex character, dealing with themes of loss, responsibility, and redemption.
By choosing to adapt this specific storyline, Gunn and the DCU team are signaling their commitment to mature, character-driven storytelling. This approach aligns with the broader vision for the DCU, which aims to balance spectacle with emotional depth and authenticity.
Fan Reactions and Rising Expectations
The news of Gunn’s glowing endorsement has sent ripples of excitement through the DC fan community. Social media platforms have been buzzing with speculation about what makes Alcock’s performance so special and what it might mean for the future of the character. Many fans have expressed their confidence in Gunn’s judgment, citing his previous successes in casting and character development.
The anticipation for Supergirl: Woman of Tomorrow has been building steadily since Alcock’s casting was announced. Her brief appearance in Superman only served to whet fans’ appetites for more. Now, with Gunn’s enthusiastic endorsement, expectations have reached new heights. This level of anticipation can be both a blessing and a challenge, as it creates pressure for the film to deliver on the promise of Gunn’s praise.
However, if Gunn’s track record is any indication, fans have every reason to be optimistic. His ability to exceed expectations and deliver memorable, emotionally resonant superhero films suggests that Supergirl: Woman of Tomorrow will be worth the wait.
The Broader Impact on Superhero Cinema
Gunn’s praise for Alcock also speaks to a broader trend in superhero cinema toward more nuanced and character-driven storytelling. As the genre continues to evolve, filmmakers are increasingly focused on finding actors who can bring depth and authenticity to iconic roles. Alcock’s casting represents this shift, as she brings both dramatic chops and a fresh perspective to the character of Supergirl.

The success of character-driven superhero films like Joker, The Batman, and Gunn’s own The Suicide Squad has demonstrated that audiences are hungry for more complex and emotionally engaging superhero stories. By prioritizing performance and character development, the DCU is positioning itself to meet this demand and potentially set new standards for the genre.
Looking Ahead: What’s Next for Milly Alcock and the DCU
With Supergirl: Woman of Tomorrow still over a year away from release, fans will have to wait to see Alcock’s full performance as the Girl of Steel. However, Gunn’s confidence in her abilities suggests that she will be a central figure in the DCU for years to come. The character of Supergirl has the potential to anchor multiple films and crossover events, making Alcock’s casting a crucial long-term investment for the franchise.
As the DCU continues to expand with projects like The Brave and the Bold, Swamp Thing, and Lanterns, the interconnected nature of the universe means that Alcock’s Supergirl will likely play a significant role in the broader narrative. Her performance in Woman of Tomorrow will not only establish her version of the character but also set the tone for her future appearances in the DCU.
Conclusion: A New Era for Supergirl
James Gunn’s declaration that Milly Alcock represents his “best casting choice ever” is more than just high praise—it’s a promise. A promise that the new DCU will prioritize character development, authentic performances, and emotionally resonant storytelling. As fans eagerly await the release of Supergirl: Woman of Tomorrow, Gunn’s confidence in Alcock’s abilities serves as a beacon of hope for the future of the franchise.
The combination of Alcock’s proven talent, Gunn’s visionary leadership, and the rich source material of Woman of Tomorrow creates a perfect storm of potential. If Gunn’s track record is any indication, this casting choice will not only meet expectations but redefine what it means to be Supergirl in the modern era.
As the DCU continues to take shape, one thing is clear: with Milly Alcock leading the charge as Supergirl, the future of the franchise is in capable hands. Her journey from the dragon-filled skies of Westeros to the star-spanning adventures of the DCU represents not just a career evolution, but a new chapter in superhero cinema itself.
