Milly Alcock debuts first look at ‘Supergirl’ following ‘Superman’ success

Following the success of Superman, DC Studios is wasting no time expanding its rebooted cinematic universe. On Wednesday, director James Gunn and lead actress Milly Alcock revealed the first official look at Supergirl in a joint Instagram post, teasing the arrival of a darker, more complex, (and perhaps more inebriated) Kryptonian hero.

The poster features the tagline “Look Out. 2026,” a twist on Superman’s classic phrase “Look up,” that suggests an edgier tone. Alcock’s face is not visible, but her costume, which a blend of classic comic book elements and the Woman of Tomorrow storyline, is on full display. The outfit includes the red skirt and boots fans will recognise, along with the House of El crest and a brown trench coat.

Alcock, known for her breakout performance as young Rhaenyra Targaryen in House of the Dragon, made a surprise appearance in the final moments of Superman, which released on July 11.

Describing the character, Gunn said: “She’s a mess. A total mess. While Superman was raised in a loving and supportive environment, Supergirl’s path has been far more traumatic.”

The film, inspired by the acclaimed Supergirl: Woman of Tomorrow comic miniseries by Tom King and Bilquis Evely, follows Kara Zor-El and her dog Krypto on a cosmic journey to help a young alien named Ruthye avenge her father’s death.

Craig Gillespie, best known for I, Tonya and Cruella, will direct. The cast includes Matthias Schoenaerts as villain Krem of the Yellow Hill, Eve Ridley as Ruthye Marye Knoll, and Jason Momoa as the antihero Lobo.

Supergirl is slated for release on June 26, 2026.
