Milly Alcock grew up in Sydney and went from local school plays to television work before most people even knew her name. For a while, she was just another teenager trying to make it in the Australian acting scene, taking small roles and learning the craft.
Things changed when she landed the part of Meg in the series Upright, a job that convinced her to leave school and focus fully on acting. That step brought real recognition at home, and it did not take long for Hollywood to notice.
The world met her as young Rhaenyra Targaryen in HBO’s House of the Dragon. Audiences connected with her performance, and critics praised her natural screen presence.
In 2025, she took an even bigger leap, joining the DC Universe as Supergirl. Along with fame, her career now brings in steady earnings that push her net worth into the million-dollar range.

Early Life and Background

Born in Sydney on April 11, 2000, Amelia May Alcock grew up like many kids-except her idea of “after-school activities” leaned more toward stage lights than soccer fields.
She went from Stanmore Public School to Newtown High School of the Performing Arts, the place where ambitious teens chase dreams of stage and screen.
But by sixteen, she decided classrooms were slowing her down. She dropped out, swapped textbooks for scripts, and landed the role of Meg in Upright. That single choice set her on a collision course with fame.
- Nickname: Milly (because “Amelia May” sounds more like a debutante than a rebel)
- Turning point: Leaving school at 16 for Upright
- Hometown vibe: Sydney girl with global ambition
“School was not for me. I found my people on set,” Milly once admitted, proving that sometimes the fast lane beats the safe lane.
Career Beginnings and Breakthrough
Every actor has a “blink and you missed it” phase, and Milly’s started with one-off roles in Wonderland (2014), Janet King (2017), and High Life (2017).
Small roles, quick lines, nothing that would make a family member say, “She’s going places.”
Then came Upright in 2019. Playing Meg opposite Tim Minchin, Milly wasn’t just believable-she stole scenes. Australia noticed, the Casting Guild crowned her Rising Star, and suddenly she was no longer a background name.
Global Recognition in House of the Dragon
The casting of Milly Alcock as young Rhaenyra Targaryen in HBO’s House of the Dragon turned her from an Australian talent into a global name.
The show premiered in 2022 and instantly carried the weight of Game of Thrones comparisons. Fans were skeptical. Could any prequel capture the same energy?
For Milly, it meant stepping into a billion-dollar franchise with millions of people ready to judge her every expression.
She handled it with calm precision. Her portrayal of Rhaenyra as a teenage heir-conflicted, ambitious, and occasionally vulnerable-earned praise from critics who rarely agree on anything.
Industry voices highlighted her ability to look both regal and raw, a combination that made her version of Rhaenyra unforgettable.
The role also earned her a Critics’ Choice Television Award nomination, a nod that pushed her into the Hollywood conversation for good.
And yet, it was not all fairy tale. By the second half of the season, her role transitioned to Emma D’Arcy, sparking debates among fans about who captured Rhaenyra better.
Some viewers called Alcock the emotional core of the series, while others celebrated D’Arcy’s darker, more battle-worn version.
For Milly, it meant she left the series at the height of her momentum-something that could have been a risk but instead propelled her toward bigger opportunities.
Supergirl and the Hollywood Spotlight
Fast forward to 2025, and Milly Alcock is no longer “the girl from Upright” or “the young Rhaenyra.” She is Kara Zor-El, better known as Supergirl.
James Gunn and Peter Safran’s overhaul of the DC Universe demanded new faces, and Alcock’s casting was both surprising and logical.
Surprising because she was not an obvious blockbuster choice, logical because her performance history proved she could carry complex roles.
The official announcement that she would debut as Supergirl in Superman (2025) sent headlines spinning.

Social media exploded with debates about her fit for the cape. For every skeptical fan muttering about typecasting, there were thousands celebrating the idea of a fresh face leading one of DC’s most iconic heroes.
Even Ryan Condal, co-creator of House of the Dragon, publicly congratulated her, saying the sky was “literally the limit.”
The timing could not be better. With DC repositioning itself after a string of shaky box-office runs, Alcock’s Supergirl represents not only a career leap for her but also a gamble for the studio.
The spinoff film Supergirl: Woman of Tomorrow is already scheduled for 2026, giving her the chance to lock down her place in Hollywood’s A-list.
Net Worth in 2025 and Income Sources

Milly Alcock’s net worth in 2025 is estimated to be around 2 million USD, with most credible sources landing on the two-million mark.
Numbers outside that range(like the speculative 17.9 million floating online) are more fantasy than fact.
Her financial profile fits someone who broke into global television, landed endorsement deals, and is now stepping into blockbuster films.
Income Breakdown (Estimated)
- Television roles: HBO’s House of the Dragon likely paid in the six-figure range per episode, especially after the show’s explosive reception.
- Film contracts: Her DC role as Supergirl marks the beginning of seven-figure opportunities. Major studios rarely gamble small when they cast franchise heroes.
- Endorsements and appearances: Fashion campaigns and red-carpet events contribute extra but remain secondary to acting.
- Stage and other projects: Her West End debut in The Crucible proved her range, though stage paychecks don’t stack up to TV and film.
Future Projects and Career Outlook
The Superman movie is only the beginning for Milly Alcock. DC Studios has already locked her in as the lead of Supergirl: Woman of Tomorrow, set for release in 2026.
The film draws on Tom Kingโs comic storyline, which paints Kara Zor-El in a darker, more cosmic light than past versions.
For Alcock, that means stepping into the spotlight as the face of her own franchise before she even turns thirty.
It is a heavy role to carry, and it puts her career at a crossroads. One path could turn her into a blockbuster regular.
If Superman and Supergirl both land with audiences, she could spend the next decade as one of the pillars of the DC Universe, with paychecks and fame on the same level as names like Gal Gadot or Margot Robbie.
The other path leans toward balance. Alcock could use her superhero visibility to fund and secure more intimate work in indie films or theater, carving out a career similar to Florence Pugh, who moves easily between blockbusters and smaller prestige projects.
Fans will see plenty of her no matter which way she goes. Expect red carpets from Los Angeles to London as DCโs marketing engine goes full throttle.
Expect glossy magazine spreads focusing on her โsudden rise,โ because Hollywood cannot resist framing a new star as an underdog.
And expect brands to come knocking, eager to tie her Supergirl image to strength and independence in fashion campaigns and lifestyle endorsements.
At the moment, her future looks less about fighting for survival in Hollywood and more about choosing how she wants to define her career.
Alcock has the talent, the global recognition, and now the cape. The next decade is hers to shape.
Final Thoughts
Milly Alcock has gone from Sydney kid to global star in the space of a few years. One moment, she was running through Australian TV dramas, the next she was sitting on the Iron Throne as young Rhaenyra, and now she is set to wear the cape of Supergirl.
That kind of career leap does not happen often, and it explains why so many eyes are on her next moves.
Money will follow. Two million today can look small once franchise contracts, promotion deals, and spinoffs stack up.
Hollywood is brutal but also rewarding to those who can carry both the story and the screen, and Milly has shown she can do both.
