This guide covers everything you need to know about Milly Alcock: her early life, her biggest roles, her upcoming projects, and what makes her one of the most exciting actresses working today.

Early Life and the Bold Path to Acting

Before she was riding dragons or preparing to fly through the DC Universe, milly alcock was a young girl in the inner-west suburb of Petersham in Sydney, Australia. Born Amelia May Alcock on April 11, 2000, she was raised in a family that wasn’t necessarily part of the “showbiz” world, but they certainly supported her creative spark.

Her introduction to the dramatic arts was as classic as it gets. We’ve learned that her very first taste of acting came in a school production of Little Red Rocking Hood, where she played—you guessed it—Little Red Riding Hood. That experience ignited a fire that couldn’t be put out. By the time she was a teenager, she was already landing professional gigs.

The Decision to Drop Out

Milly attended the prestigious Newtown High School of the Performing Arts in Sydney. This school is known for churning out some of Australia’s brightest talents, but Milly’s journey there took an unexpected turn. In 2018, while she was in the middle of her final year, she was cast in the Foxtel drama Upright.

She was faced with a massive choice: stay in school and get her diploma, or drop out to pursue a lead role alongside Australian icon Tim Minchin. For Milly, the choice was clear. She chose the outback over the classroom. She has since remarked that she knew school wasn’t her “thing” and that she never doubted her decision to leave. It was a “sink or swim” moment, and as we can see today, she is definitely swimming.

Early Career and Commercials

Before her big breakout, Milly was a familiar face on Australian television in a different way. Like many young actors, she started in commercials. She appeared in ads for major brands like NBN, Cadbury, KFC, and Woolworths. She also spent time as a presenter on the Disney Channel in Australia, honing her screen presence and charisma.

Breakthrough Roles and Television Success

The project that truly changed everything for milly alcock in Australia was Upright. Playing the role of Meg, a runaway teenager who hitches a ride across 2,000 miles of the Australian outback with a struggling musician (Tim Minchin), Milly showed a depth and grit that belied her age.

The chemistry between Alcock and Minchin was electric. The show was a critical darling, and it earned her a nomination for Best Comedy Performer at the 10th AACTA Awards in 2020. At the time, she was one of the youngest nominees in the category. This role proved she could carry a series and handle complex, emotional material.

Entering Westeros

While Upright made her a star in Australia, House of the Dragon made her a star across the globe. Cast as the young Princess Rhaenyra Targaryen, Milly had the monumental task of introducing audiences to the Game of Thrones prequel. The pressure was immense—fans were skeptical after the original series ended, but Milly’s performance was so captivating that she silenced the doubters within the first hour.

She played Rhaenyra for the first five episodes of the first season, portraying a princess who was both rebellious and deeply aware of the weight of her heritage. Her portrayal earned her a Critics’ Choice nomination for Best Supporting Actress in a Drama Series.

Comparing Major TV Performances

To understand her range, let’s look at how her two biggest TV roles stack up:

Feature	Meg (Upright)	Rhaenyra (House of the Dragon)
Setting	Modern Australian Outback	High Fantasy Westeros
Character Vibe	Gritty, foul-mouthed, resourceful	Stoic, regal, defiant
Critical Reception	80% Tomatometer / 94% Audience	90% Tomatometer / 86% Audience
Key Skill Shown	Comedic timing & emotional vulnerability	Commanding presence & subtle intensity

Milly Alcock in the DC Universe and Beyond

If you thought dragon-riding was the peak of her career, think again. In early 2024, it was officially announced that milly alcock would be joining the new DC Universe (DCU) as Kara Zor-El, better known as Supergirl.

James Gunn, the mastermind behind the new DCU, chose Milly after seeing her “intensity” in House of the Dragon. This version of Supergirl is expected to be a bit “darker” and more “edgy” than previous iterations, drawing inspiration from the Supergirl: Woman of Tomorrow comic book run.

Upcoming Projects

Milly’s schedule is looking incredibly busy. Here is what we have to look forward to:

• Superman (2025): She is expected to make a cameo appearance as Supergirl in the upcoming film directed by James Gunn, setting the stage for her solo outing.
• Supergirl: Woman of Tomorrow (2026): This will be her first leading role in a major Hollywood blockbuster. The film is currently in production and is one of the most anticipated superhero movies of the decade.
• Sirens (Netflix): Milly is set to star in this dark comedy limited series alongside Julianne Moore and Meghann Fahy. The show is based on the play Elemeno Pea and follows three sisters at a luxury beach estate.

Notable Awards and Nominations

Milly’s talent hasn’t gone unnoticed by the industry. Here is a summary of her accolades so far:

• Winner: Casting Guild of Australia – Rising Stars of 2018.
• Nominated: Critics’ Choice Television Award – Best Supporting Actress in a Drama Series (House of the Dragon).
• Nominated: AACTA Award – Best Comedy Performer (Upright).
• Nominated: Saturn Award – Best Performance by a Younger Actor in a Network or Cable Series.

Artistic Versatility: Theater, Film, and Media

While television has been her primary medium, milly alcock is a true multi-hyphenate. She isn’t afraid to step onto the stage or appear in different types of media to stretch her creative muscles.

The Crucible and the West End

In 2023, Milly made her professional stage debut in London’s West End. She played the role of Abigail Williams in a new production of Arthur Miller’s The Crucible at the Gielgud Theatre. Taking on such an iconic and difficult role in a legendary theater was a massive risk, but she received rave reviews for her performance. This move coincided with her relocation from Sydney to London in 2022, marking her transition into a truly international actress.

Film and Music Videos

Milly’s film career is also expanding. Her first feature film was the 2018 horror movie The School, where she played the role of Jien. While the film was a smaller production, it gave her the necessary experience to handle the rigors of a movie set.

In an interesting turn, she also appeared in the music video for Noel Gallagher’s High Flying Birds’ song “Easy Now” in 2023. It’s a testament to her “cool factor” that a rock legend like Gallagher would want her to lead his video.

Personal Life and Social Media

Despite her massive fame, Milly remains relatively private. She is active on Instagram under the handle @millyalcock, where she shares a mix of professional shots, behind-the-scenes glimpses, and personal moments. She has a brother named Bert Alcock and remains close with her family back in Australia. Before her big HBO break, she was actually living in her family’s attic and washing dishes to make ends meet—a true “started from the bottom” story!
