Milly Alcock is set to portray the iconic DC heroine in the upcoming film Supergirl: Woman of Tomorrow. In a recent interview, the House of the Dragon actress teased details regarding her character's costume and her own lack of superhero cinema experience .

A surprising lack of Marvel and Wonder Woman experience

In a move that deviates from the typical preparation seen in major franchise casting, Milly Alcock admitted she has not viewed the most prominent female-led superhero films. According to the report, the actress has not seen Marvel Studios' Black Widow or Captain Marvel, nor has she watched Gal Gadot’s 2017 Wonder Woman.

While most actors attempt to study the precedents of their roles, Alcock joked that her lack of research was "probably not great" and suggested she "should just lie" about it. This lack of familiarity with the genre's established tropes may offer a fresh, unburdened perspective to the character as she enters the expanding DC Universe.

Why the iconic Supergirl suit won't be a constant fixture

Alcock teased that the presentation of the Supergirl costume will differ significantly from what fans might expect. While the bright, iconic suit is a staple of the character, the actress suggested that the garment will not be a constant presence on screen.

The report says Alcock described the use of the suit as part of a "journey," implying that the costume's appearance is tied to the character's emotional and narrative progression. By de-emphasizing the constant use of the uniform, the film may focus more on the person beneath the cape rather than the spectacle of the superhero archetype.

The emotional bond between Supergirl and Ruthye Marye Knoll

The narrative core of the film appears to hinge on the relationship between Supergirl and a young girl named Ruthye Marye Knoll, played by Eve Ridley. alcock explained that the two characters share a deep kinship born from shared hardship.

Through the process of helping Ruthye navigate the trauma of losing her entire family, Supergirl is forced to confront her own internal struggles. Alcock noted that the character must set aside her own feelings to assist others, a process that ultimately allows her to "save herself."

Building the DCU with Craig Gillespie and James Gunn

The production of Supergirl: Woman of Tomorrow is a key component of the new DCU strategy led by James Gunn and Peter Safran. The film is directed by Craig Gillespie and features a screenplay written by Ana Nogueira.

The story is drawn from the acclaimed eight-issue comic miniseries by Tom King and Bilquis Evely.. With a scheduled theatrical release date of June 26, 2026, the project represents a significant pillar in the studio's effort to redefine its cinematic universe through character-driven storytelling.

What DC and Craig Gillespie are hiding about the suit's debut

Despite the teasers provided by Alcock, several specific details regarding the film's visual direction remain unverified. It is still unknown exactly when the character will first don her iconic suit, or how much the design will deviate from the classic comic book aesthetic. Furthermore, the report only provides Alcock's perspective, leaving the official stance of DC and director Craig Gillespie on these creative choices unaddressed.
