Milly Alcock has been cast as Supergirl for upcoming Warner Bros. projects in the new DC Universe helmed by James Gunn and Peter Safran.
Reports published on Monday revealed that the House of the Dragon star screen-tested for Gunn and Safran earlier this week, and has been officially casted as the Kryptonian cousin of Superman for several titles. She’s expected to make her debut in the upcoming Superman: Legacy before starring in her own film, Supergirl: Woman of Tomorrow.
When exactly Supergirl: Woman of Tomorrow will arrive is unknown, but according to The Hollywood Reporter, the film may begin shooting as soon as this fall. Though it has yet to lock-in a director, Ana Nogueira is writing the script.
The upcoming Supergirl film is based on an eight-issue miniseries by writer Tom King and artist Bilquis Evely, published by DC Comics in 2021 and 2022. The film was first announced in January 2023. This past November, Gunn expressed his excitement for the adaptation, praising Nogueira — who appeared in the original Vassar workshop production of Hamilton — as “an amazing writer” who’s screenplay is “above and beyond anything I hoped it would be.”
In January 2023, Gunn gave fans an indication of what they could expect from upcoming titles, and described the new take on Supergirl as “a much more jaded character” than Superman, due to her upbringing on a harsh, volatile “chunk of Krypton.” In that message, he said the movie would be a “big, science-fiction, epic film.”
Now, news of her casting confirms that Alcock has beaten several other contenders for the role, including Meg Donnelly. Alcock started her acting career in 2014 and rose to prominence due to her portrayal of the young Rhaenyra Targaryen on HBO’s House of the Dragon, which premiered in 2022. The series’ second season was named by Consequence as one of 25 most anticipated TV shows of 2024.
Previously, Supergirl has been portrayed by Faye Dunaway (for the 1984 film Supergirl), Melissa Benoist (for the CW series), and Sasha Calle (for last year’s The Flash).
