Supergirl Star Milly Alcock Says Starring in Game of Thrones Spinoff House of the Dragon 'Made Me Aware That Simply Existing as a Woman in That Space Is Something People Comment On'
- Milly Alcock reflects on her experience working on the Game of Thrones spinoff House of the Dragon and how it prepared her for scrutiny in the superhero genre.
Milly Alcock is set to play Supergirl in the next big DC Universe movie, and with that comes an intense scrutiny from fans. But, she says, she already has experience working under the microscope of fandom: on Game of Thrones spinoff House of the Dragon .
Alcock played the younger version of Rhaenyra Targaryen in the HBO show, and won plaudits for her performance. Off the back of that, she was cast as Kara Zor-El in the follow-up to James Gunn's Superman, in which she made a cameo. Now, Alcock is firmly rooted in the rebooted DCU, headlining a movie of her own, and may end up in subsequent DCU movies such as next year's Man of Tomorrow.
And so, in an interview with Vanity Fair , Alcock was asked if "the famously fickle Game of Thrones fandom" had prepared her for "the inevitable backlash." She replied to say that due to her experience working on House of the Dragon, she understands that she will get comments about her appearance, but it sounds like she won't let them bother her.
"It definitely made me aware that simply existing as a woman in that space is something that people comment on. We have become very comfortable having this weird ownership of women's bodies," she said. "I can't really stop them. I can only be myself."
According to the interview, Alcock told herself she'd never do another big franchise project after wrapping up House of the Dragon, but she started to get anxious after failing to work for a year. "I was so s**t-scared that my life was over at 22," she said. "And, of course, it wasn't."
She was similarly dismissive of concerns about the superhero genre expressed by the likes of Martin Scorsese and Ridley Scott. Scorsese famously said Marvel movies were "not cinema," and Ridley Scott called superhero movies "boring as s**t," with scripts that "aren't any f***king good."
Supergirl, previously known as Supergirl: Woman of Tomorrow, is set to soar into theaters on June 26, 2026, and reintroduce us to Milly (House of the Dragon) Alcock's Kara Zor-El after she made quite a first impression in Superman.
Supergirl is based on Tom King and Bilquis Evely's 2021-2022 comic book series, Supergirl: Woman of Tomorrow, and will be a "space fantasy" that will have a different tone than Superman. While we still have a lot more to learn about the upcoming DCU film, we are starting to learn who will be joining Kara in the film, and we're here to break that all down for you!
"I mean, I think as we learn, she's had a completely different background from Superman," Gunn continued. "A much more difficult background. He's had this wonderful upbringing by these two parents that loved him and were very healthy. And her background was much different than that. And she's ended up different than her cousin."
Kara was on a piece of Krypton that drifted away from the planet, and she had to live there for the first 14 years of her life. According to Gunn, she was in a "horrible situation where she watched everyone around her die. So, she's a much harsher and more f*cked up Supergirl than you've been used to thus far."

Milly Alcock as Supergirl / Kara Zor-El
As previously mentioned, Milly Alcock will star as Kara Zor-El in Supergirl, and James Gunn has already shared that Superman's cousin is a "mess. She's a total mess."
"I mean, I think as we learn, she's had a completely different background from Superman," Gunn continued. "A much more difficult background. He's had this wonderful upbringing by these two parents that loved him and were very healthy. And her background was much different than that. And she's ended up different than her cousin."

All of this explains why Krypto sometimes acts the way he does while also being a wonderful dog, and we should learn more about him in Supergirl.

Krypto
We will most likely be seeing much more of the wonderfully chaotic Krypto, as we discover in Superman that she is actually Supergirl's dog, and Superman was just watching over him while she was gone. This was when we also learned, via Kal-El, that Kara "likes to go and party on other planets. Planets with red suns. Because of our metabolism, we can't get drunk on a planet with a yellow sun."

Jason Momoa as Lobo
After starring as Aquaman in the DCEU, Jason Momoa will officially join the DCU as Lobo in Supergirl. Lobo was always Momoa's favorite character, and he had previously stated it would be "the perfect role" for him. Soon, we'll get to see that dream come true.

Matthias Schoenaerts as Krem of the Yellow Hills
Via Deadline, Rust and Bone's Matthias Schoenaerts is set to portray the big villain of Supergirl, Krem of the Yellow Hills. Krem was the main antagonist in King and Evely's Supergirl comic that serves as the film's source material, and his actions very well may lead to Supergirl joining the party.

Eve Ridley as Ruthye Marye Knoll
Via Deadline, 3 Body Problem's Eve Ridley will take on the role of Ruthye Marye Knoll. In the comics, Knoll is a noble and honorable warrior, and one of the key people who draws Supergirl into a conflict we won't spoil here in case it is adapted from the comics to the big screen.

David Krumholtz as Zor-El
Via THR, Supergirl will be a family affair, as Oppenheimer's David Krumholtz will be playing Kara Zor-El's father, Zor-El.

Emily Beecham as Alura In-Ze
Via THR, 1899's Emily Beecham will play Supergirl's mother, Alura In-Ze. If the post-credits scene of Superman is any indication, Alura and Zor-El probably have their hands full with Kara!

Will David Corenswet's Superman Appear in Supergirl?
While nothing has been confirmed, it could make a lot of sense for David Corenswet's Superman to appear in Supergirl. We still have a lot to learn about their relationship as cousins, as well as more about Krypton's past, so an appearance by good ol' Kal-El very well may be in the cards!
"I get it. They've been around for f***ing ever making phenomenal films," Alcock said. "Not every film is for everyone. The beauty of art is that you can be selective."
Alcock's comments arrived alongside a new Supergirl trailer , which shows a lot more of Jason Momoa's Lobo. We also see David Corenswet's Superman make a brief appearance, and find out that Krypto the Superdog only has three days to live. Supergirl hits theaters on June 26, 2026.
