Milly Alcock has been announced as the lead in the upcoming film Supergirl, set to be released in theaters on June 26, 2026. Alcock, who is 25 years old, previously gained recognition for her role as young Rhaenyra Targaryen in HBO’s House of the Dragon.
The film, directed by Craig Gillespie, features Alcock portraying Kara Zor-El, who embarks on a journey of self-discovery. The screenplay is penned by Ana Nogueira, and the story involves Supergirl facing a formidable adversary, a space-faring crime lord played by Matthias Schoenaerts.
In Supergirl, Alcock’s character must retrieve an antidote within three days, showcasing the urgency of her mission. The film also introduces Krypto, Supergirl’s loyal dog, adding a unique element to the narrative.
Alcock has expressed her feelings of ownership regarding women’s bodies in the industry, highlighting the challenges faced by actresses. She has previously shared her struggles with career anxiety, particularly at the age of 22, stating, “I was so shit-scared that my life was over at 22. And, of course, it wasn’t.”
Raised in Petersham, a middle-class suburb in west Sydney by a single mother, Alcock began pursuing acting at a young age, cold-calling talent agencies at just 13 years old. Her mother encouraged her to follow her passion, saying, “If those idiots can do it, why can’t you?”
As Alcock steps into the role of Supergirl, she joins a growing list of actors in the DC Extended Universe. The film is part of a broader strategy by Warner Bros., under the guidance of James Gunn and Peter Safran, to revitalize its superhero franchises.
First reactions to Alcock’s casting have been largely positive, with fans eager to see her interpretation of the iconic character. The anticipation surrounding the film continues to build as the release date approaches.
Details remain unconfirmed regarding additional cast members, but the excitement for Alcock’s performance is palpable. As she takes on this significant role, many are watching closely to see how she will bring Kara Zor-El to life on the big screen.
