House of the Dragon’s Milly Alcock Is James Gunn’s Supergirl

James Gunn has officially announced the casting of Milly Alcock as Supergirl in the newly reimagined DC Universe.

Alcock, widely recognised for her portrayal of young Princess Rhaenyra Targaryen in HBO’s House of the Dragon, will bring a fresh perspective to the iconic role. She emerged as the top choice for the role, surpassing contenders such as Emilia Jones from CODA and Meg Donnelly, who previously voiced Supergirl in DC’s animated productions.

Although unconfirmed, there are speculations that Alcock’s Supergirl might make an appearance in James Gunn’s Superman: Legacy. Her confirmed debut will be in the solo feature, Supergirl: Woman of Tomorrow, which is still in search of a director. The screenplay is penned by Ana Nogueira, known for her work on The Vampire Diaries.

Gunn previously described the new Supergirl as a more complex and hardened character. Unlike Superman, who was raised on Earth from infancy, Supergirl, or Kara Zor-El, experienced a traumatic upbringing on a fragment of Krypton, witnessing death and destruction. This background imbues her with a grittier, more intense demeanor compared to previous incarnations.

Alcock’s introduction to the DC Universe represents a significant step in the franchise’s evolution. Her role as Rhaenyra Targaryen in House of the Dragon has already garnered acclaim, demonstrating her capacity to embody powerful and nuanced characters. The actress joins a notable lineage of actors who have portrayed Supergirl, including Melissa Benoist in the CW series and Sasha Calle in the 2023 film The Flash.
