From Washing Dishes to Dragons: Supergirl Star Milly Alcock’s Sudden Targaryen Breakout
From scrubbing dishes in a Sydney kitchen to soaring as House of the Dragon’s breakout and DC’s new Supergirl, Milly Alcock lays bare the grind behind a meteoric rise.
Before Milly Alcock put on the cape, she was scrubbing pans. In a new Variety profile, the future Kara Zor-El walks through the not-glamorous stretch of her life in Sydney, and it is a great reminder that the so-called overnight success usually clocks a lot of shifts first.
From attic life to open kitchen
Years before she was young Rhaenyra Targaryen on House of the Dragon, Alcock was bouncing between auditions and restaurant work back home in Sydney. Even after landing a big part on the Australian series Upright, her day-to-day stayed stubbornly normal: she was still living in her family ’s house, tucked into the attic because there was no space anywhere else. She joked she basically sounded like a Roald Dahl character.
While juggling roles and callbacks, she took a dishwashing job at a busy restaurant with an open kitchen. Not exactly stealth duty when you are new to TV and still figuring everything out.
"I was a stick of a thing. I was washing these dishes so proudly and so terribly, and it was an open kitchen so everyone could see me."
That stage was all uncertainty and side gigs — the kind of reality where you can be on a show and still punch the clock, hoping the next break actually moves the needle. Cut to today: Alcock is the face of DC ’s next big swing.
When Supergirl got real
Alcock says the moment it truly clicked came the first time she walked onto set in the Supergirl suit. Chantal Nong, DC Studios’ executive vice president of production, immediately teared up. Alcock hugged her, asked if she was OK, and then it hit her: this was bigger than just a costume fitting. She felt the weight of it — her word was responsibility.
Only later did Nong explain why she got emotional: she had spent years trying to bring Supergirl to the screen. Producer Peter Safran also recalled that the instant Alcock stepped out, the whole set felt like she was the character. That is one of those telling behind-the-scenes moments — when an office of development history suddenly lands on a performer’s shoulders.
