Milly Alcock’s Supergirl Suit Revealed in Superman BTS Photo
A new behind-the-scenes photo has revealed DC Studios’ first clear look at Milly Alcock as Supergirl. Shared during the release window of Superman (2025), the image offers a detailed glimpse of her costume ahead of her solo debut in Supergirl: Woman of Tomorrow.

The images, originally shared by co-department head of hair Lindsay McAllister on Instagram, show Alcock on set at the Fortress of Solitude, where her character Kara Zor-El appears briefly in Superman’s final act. McAllister later deleted the original post.
Alcock’s cameo marks the first live-action DC movie appearance featuring both Superman and Supergirl. In the scene, a visibly intoxicated Kara arrives to pick up Krypto. This moment introduces the first on-screen interaction between the Kryptonian cousins in the new DC Universe.
Alcock will lead the Supergirl: Woman of Tomorrow film, set to release on June 26, 2026. Her costume, seen clearly in the BTS images, closely matches David Corenswet’s Superman suit. The design reflects a unified Kryptonian look for the DCU.
James Gunn previously confirmed that Alcock’s Supergirl is based on the Woman of Tomorrow comic by Tom King and Bilquis Evely. Gunn described her version of Kara as “much more hard-core,” emphasizing the difference in upbringing between her and Superman.
“We will see the difference between Superman, who was sent to Earth and raised by loving parents from the time he was an infant, versus Supergirl, raised on a rock… and who watched everyone around her die,” Gunn told The Hollywood Reporter back in 2023.
Production on Supergirl is underway at Warner Bros. Studios Leavesden, with Craig Gillespie directing and Ana Nogueira writing. Alcock appears alongside Matthias Schoenaerts as Krem of the Yellow Hills and Eve Ridley as Ruthye Mary Knolle. The character’s introduction in Superman serves as a narrative lead-in to her solo film next year.
