Milly Alcock is carving out Kara Zor-El's own path in James Gunn's DC Universe. The British actress, fresh off her breakout turn as young Rhaenyra in HBO's "House of the Dragon," explains that her Supergirl functions as a completely independent hero, separate from David Corenswet's Superman reboot.
This strategic separation matters for the DCU's narrative foundation. Gunn's interconnected universe launches with Corenswet's "Superman: Legacy," positioning the Man of Steel as the franchise cornerstone. But Alcock's Supergirl isn't riding his coattails. Instead, she operates in her own sphere, establishing Kara as a distinct force with her own mythology, relationships, and conflicts to explore.
The move reflects how modern superhero franchises approach legacy characters. Rather than defaulting to family dynamics or mentorship arcs, the DCU opts to let Supergirl build her own rogues gallery and emotional stakes. This approach worked for "Wonder Woman," which thrived by centering Diana's agency rather than tying her solely to male heroes. It's the same philosophy here.
Alcock's casting signals Gunn's confidence in the character's standalone potential. She brings credibility and range from "House of the Dragon," where she delivered nuanced work in a complex ensemble. That pedigree suggests Supergirl won't be auxiliary material but rather a genuine pillar franchise possibility.
The DCU's architecture has shifted dramatically from Zack Snyder's interconnected universe and the Snyderverse's aftermath. Gunn emphasizes character specificity and thematic coherence over sprawling crossovers. Each hero gets their moment. Each story matters on its own terms.
For audiences, this means Supergirl enters theaters as her own story
