You probably know her as the fierce young princess from House of the Dragon or the upcoming star of DC’s Supergirl: Woman of Tomorrow. She has that distinct, sharp energy on screen that makes her impossible to ignore. But if you’ve ever found yourself wondering about the person behind the blonde Targaryen wig, you’re definitely not alone. Most fans just call her Milly, but Milly Alcock full name is actually Amelia May Alcock.
It’s a classic, almost old-school name that feels a world away from the gritty, dragon-riding world of Westeros.
Why Amelia Became Milly
Honestly, "Amelia" sounds a bit formal, doesn't it? It has a certain weight to it. In the industry, she’s gone by Milly for as long as most of us have been paying attention. It’s punchy. It’s memorable. It fits her "cool girl" Aussie vibe perfectly. Born on April 11, 2000, in Sydney, New South Wales, she grew up in the suburb of Petersham.
Before the HBO fame, she was just Amelia, a kid who loved acting so much she eventually dropped out of the Newtown High School of the Performing Arts. Why? Because she landed a role in the Australian series Upright. She chose the work over the diploma. Bold move. It clearly paid off.

The Middle Name You Didn't Know
The "May" in Amelia May Alcock adds a soft touch to a name that now carries a lot of Hollywood power. Most people don't use it. You won't see it on a movie poster. But it’s there on the birth certificate.
She has two younger brothers, and by all accounts, her upbringing was pretty grounded despite her early start in commercials for brands like Cadbury and KFC. Can you imagine the girl who would become Rhaenyra Targaryen selling you chocolate? It happened.
Milly Alcock Full Name: From Sydney to the Stars
When James Gunn announced she would be the new Supergirl, the internet basically exploded. He didn't just pick any actress; he specifically wanted that "attitudinal" edge she brought to her earlier roles. It’s funny to think that Milly Alcock full name was being whispered in the halls of DC Studios long before the rest of us knew the casting was official.

Gunn actually mentioned that he first noticed her in House of the Dragon. He saw that grit.
The Career Shift
- Early Days: Starting in 2014 with a tiny role in Wonderland.
- The Big Risk: Leaving school in 2018 to star in Upright as Meg.
- The Global Breakout: Casting as Rhaenyra in 2021 (while she was washing dishes in a restaurant!).
- The Future: Joining the DCU as Kara Zor-El.
What Most People Get Wrong
There’s a common misconception that she’s "new" to the scene. She isn't. She’s been working since she was 13. By the time the world saw her as a Targaryen, she already had an AACTA nomination under her belt. People also sometimes confuse her with other rising Aussie stars, but there's a specific "raw" quality to her acting that sets Amelia May Alcock apart.
She isn't interested in being a polished, perfect starlet. She’s stated in interviews that she prefers characters who are a bit messy. Relatable.

The "Super" Future for Amelia May Alcock
With the Supergirl movie set for 2026, her name is about to be everywhere. Again. This version of Kara Zor-El is expected to be more jaded and "hardened" than the versions we've seen on TV before. It’s based on the Woman of Tomorrow comics, where Supergirl is basically a space-faring badass who has seen some things.
If you want to see what she's doing right now, check out the Netflix series Sirens. She stars alongside Julianne Moore, and it’s a great way to see her range outside of the fantasy/superhero genres.
Milly Alcock full name represents a journey from a Sydney schoolgirl to a global icon. Whether she's Amelia or Milly, she’s clearly here to stay.
To keep up with her latest projects, keep an eye on DC’s official production updates for 2026. If you haven't seen her early work, I highly recommend tracking down Upright—it’s where you really see the spark that started it all.
