Milly Alcock has recently revealed that it is not Kara Zor-El’s fists or flight that drew her to the role, but the emotional strength behind the icon that truly drew her to the role. Whenever Earth slips into chaos, the DC Universe has always turned to its titans to restore order, with Batman rising from Gotham’s shadows or Superman descending from the skies as humanity’s last hope. And as James Gunn rebuilds the franchise for a new era, Milly's Supergirl now looks ready to become one of the defining forces of the new DCU.

While speaking at CinemaCon 2026 in Las Vegas, Milly said Supergirl’s brute strength and larger-than-life abilities never drew her in. Instead, what captivated her was Kara’s power to endure devastating trauma, survive extraordinary loss, and still rise with resilience. For Milly, Supergirl’s greatest strength is not what she can break, but what she can survive and still overcome.

"I was never really attracted to her physical powers or ability. I think that like for me the most astonishing and surprising powers are her like emotional kind of powers are her ability to kind of go through this terrible terrible event and life and have so much resilience." Milly told Fandango.

Indeed, that inner strength now fuels Milly's cosmic chapter as Supergirl hits theatres on June 26, 2026. While Superman grew up in the warmth of Earth, this Kara spent 14 brutal years on a drifting shard of Krypton, watching every life around her perish. From that ruin, the film sends her across the galaxy on a fierce quest for vengeance and justice alongside a young alien girl named Ruthye.

While Kara has been portrayed by several stars before, Milly seems to have taken the mantle to another level.

Craig Gillespie praises Milly Alcock’s Supergirl performance

Before stepping into the cape, the 26-year-old Australian actress had already conquered global screens through her breakout turn as young Rhaenyra Targaryen in House of the Dragon. And now, proving that same fire has only grown stronger, director Craig Gillespie said Milly's casting thrilled him and strongly pulled him toward the project. He praised the rare blend of vulnerability, accessibility, and strength she brings to the screen, adding that seeing those qualities collide with Ana Nogueira’s script felt amazing.

The film also loads its cosmic battlefield with a stacked cast, with Jason Momoa charging in as bounty hunter Lobo, Matthias Schoenaerts ruling as villain Krem of the Yellow Hills, and Eve Ridley joining as Ruthye, the young girl who pulls Kara into a revenge mission. David Krumholtz and Emily Beecham play Kara’s Kryptonian parents.

Adapted from the 2021–2022 comic miniseries Supergirl: Woman of Tomorrow by Tom King and Bilquis Evely, Milly has even urged curious fans to read the comics if they want to know what is quietly brewing behind Supergirl.

And while many DC heroes save worlds through raw power, Milly Alcock’s Supergirl now seems ready to prove that emotional strength may be the greatest power of all.
