Milly Alcock Says She Stayed “Really True” to the Woman of Tomorrow Comic for ‘Supergirl’

Milly Alcock has been open throughout the ‘Supergirl‘ press tour about the enormous pressure of stepping into the cape, and a new clip posted by Variety captures her distilling that experience into a single honest sentence.

The actress says she stayed “really true” to Tom King’s comic book series when developing her portrayal of Kara Zor-El, then “crossed my fingers and hoped for the best.”

That approach was not a passive one. Alcock has described being immediately consumed by the source material when she first read it, telling Den of Geek that she was “so seduced by the colors and the imagery of the world Tom King and Bilquis Evely presented” and was surprised to find such a “messy, resilient, and incredibly kind person within the book.”

Her connection to Kara went beyond the page. In her in-depth Variety cover story, Alcock reflected that her personal experience during production mirrored Kara’s own arc, saying she found herself going through a journey of self-doubt and eventual confidence that ran in parallel with where the character needed to go. She described the film as the closest she has ever come to playing herself.

James Gunn, who cast Alcock after seeing her in ‘House of the Dragon,’ later wrote from the set of the ‘Superman’ sequel that he had always believed she would bring “an innate edge I thought Supergirl needed.” Producer Peter Safran recalled the audition as an immediate consensus moment, saying “everybody had tears in their eyes” and that the assembled creative team looked at each other and agreed she was “absolutely perfect.”

The comic that shaped her preparation, Tom King’s ‘Supergirl: Woman of Tomorrow,’ has been widely credited with reimagining Kara Zor-El as an emotionally complex, world-weary hero rather than a simple counterpart to her cousin. King, who is consulting on more than a dozen DC Studios projects, has said that adapting the series for the screen required “letting it go” and trusting the filmmakers to do something meaningful with his take on the character.

First reactions from early screenings drew widespread comparisons to ‘Mad Max,’ with critics noting that the film has a deliberately grimy, otherworldly quality far removed from the clean superhero aesthetic that defines most DCU entries. The tonal gamble has generated divided reviews, but Alcock herself has been singled out for praise in nearly every notice the film has received.

At the film’s world premiere in Brooklyn, she also spoke about the queer readings that fans have applied to Kara, telling Variety she is “really honored” that the LGBTQ+ community has connected with a character she describes as someone who “doesn’t live inside the binary of what we think a woman should be.” Whatever the film’s final box office result, the performance at its center clearly reflects someone who treated the source material with genuine care.
