It's official: House of the Dragon's Milly Alcock is DC's new Supergirl

James Gunn and Peter Safran are in the midst of rebooting the DC Cinematic Universe. That means a new guy playing Superman (David Corenswet), a new guy playing Batman (no announcement yet) and a new woman playing Supergirl, who will be introduced in the Gunn-directed Superman: Legacy before getting her own movie in Supergirl: Woman of Tomorrow.

A couple weeks back, we wrote about several actresses in the running the play Supergirl, including CODA star Emilia Jones, Priscilla star Cailee Spaeny, Meg Donnelly — who has actually voiced Supergirl in DC animated movies — and Milly Alcock, who we all remember as Young Rhaenyra Targaryen from House of the Dragon.

It eventually came down to Alcock and Donnelly. Now, Deadline has announced that Alcock has officially won the role. As Game of Thrones fans, of course we support this choice. After all, is there really muich difference between flying around King's Landing on a dragon and flying around Metropolis on your own power? Congratulations to Milly Alcock!

In DC comics, the best known version of Supergirl is Kara Zor-El, Clark Kent's cousin. Unlike Clark, who was born on the planet Krypton but crashed to Earth as a baby and was raised by the kindly Kent family, Kara grew up on a fragment of Krypton floating out in space, so she's more in touch with her Kryptonian roots. Here's how Gunn put it in a statement:

" 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."

We have yet to see whether Gunn and Safran's revamped DC Cinematic Universe will take flight with audiences. For years, Warner Bros. Discovery tried to make an interconnected series of DC Comics movies work, most of them based on ideas from director Zack Snyder, but they kind of petered out with diminishing returns. Hopefully Alcock is part of a new wave that rights the ship.
