The new DC Universe headed up by James Gunn and Peter Safran has added yet another important piece, with Milly Alcock signing on as the new Supergirl.
The 23-year-old Australian actress’ casting was first reported by Deadline on Monday, though Gunn, 57, quickly confirmed the news on Instagram.
‘This is accurate. Milly is a fantastically talented young actor, and I’m incredibly excited about her being a part of the DCU,’ said Gunn, who confirmed in September that three existing DC Extended Universe (DCEU) characters will return in his DC Universe (DCU).
‘Yes, I first became aware of her in House of the Dragon but I was blown away by her varied auditions and screen tests for #Supergirl,’ he added.
‘She embodies Kara as envisioned by @tomking_tk and @bliquis and Ana Noguiera,’ Gunn concluded.

The character will be based on the 2021-2022 eight-issue comic miniseries Supergirl: Woman of Tomorrow, created by writer Tom King and artist Bliquis Evely.
Ana Nogueira signed on to write the screenplay for the film adaptation of Supergirl: Woman of Tomorrow, which Alcock will star in.
Alcock ultimately beat out Emilia Jones (Coda) and Meg Donnelly, who had previously voiced Supergirl in animated films like Legion of Superheroes.
There has been talk that, while Supergirl: Woman of Tomorrow will be her first major project in the DCU, Alcock is rumored to put in an appearance in Superman: Legacy.
Superman: Legacy is the first project under Gunn and Peter Safran’s leadership, with production scheduled to begin this March at Trilith Studios in Atlanta.
Warner Bros. has already set a July 11, 2025 release date for Superman: Legacy, which stars David Corenswet as Superman and Rachel Brosnahan as Lois Lane.
The cast also includes Isabela Merced (Hawkgirl), Nathan Fillion (Guy Gardner), Skyler Gisondo (Jimmy Olsen), Anthony Carrigan (Rex Mason), Sean Gunn (Maxwell Lord), Edi Gathegi (Mister Terrific), Maria Gabriela de Faria (Angela Spica) and Sara Sampaio (Eve Teschmacher).
While it’s unclear if Alcock’s Supergirl will appear in Superman: Legacy, it was said that she will appear in one DCU project before Supergirl: Woman of Tomorrow.

Alcock is best known for playing Rhaenyra Targaryen in HBO’s House of the Dragon, which debuted in 2022
The Supergirl character was created by Otto Binder and Al Plastino in 1959, though this version of the character based off King and Evely’s comic is said to be much different than on-screen iterations fans have seen in the past.
‘In our series we see the difference between Superman who was sent to Earth and raised by loving parents from the time he was an infant, versus Supergirl who was raised on a rock, a chip off Krypton, and watched everyone around her die and be killed in terrible ways for the first 14 years of her life, and then came to Earth when she was a young girl. She’s much more hardcore; she’s not exactly the Supergirl we’re used to seeing,’ Gunn said when the first wave of DCU projects were announced in January 2023.
Supergirl has previously been played on film by Helen Slater in 1984’s Supergirl and Sasha Calle in 2023’s The Flash.
She was played on the small screen by Laura Vandervoort in The CW’s Smallville and later by Melissa Benoist in The CW’s Supergirl.
Alcock is best known for playing Rhaenyra Targaryen in HBO’s House of the Dragon, which debuted in 2022.
