Milly Alcock, the talented Australian actress who rose to prominence in HBO’s hit series *House of the Dragon*, is set to return to the big screen with her role as Supergirl. The film, a spinoff from the iconic Superman franchise, is scheduled for release in UK cinemas on June 26.
In a recent interview with *Vanity Fair*, Alcock spoke candidly about her initial anxiety regarding her career trajectory following her breakout role as a young Rhaenyra Targaryen in *House of the Dragon*. The 25-year-old actress admitted, “I was so s— scared that my life was over at 22,” after her character’s arc concluded, leaving her with a sense of uncertainty about her next steps. Despite her fears, she has embraced the challenge of stepping into a leading role in *Supergirl*, stating that she “kind of bullied myself into” taking on the part.

Alcock’s acting career began in the mid-2010s, but she gained significant recognition through her work in *House of the Dragon*, which premiered in 2022. Although her appearance as Rhaenyra was brief—spanning just five episodes in the first season—her portrayal captivated audiences. The show’s extensive timeline allowed her character to be revisited in subsequent episodes, but Alcock still found herself seeking new opportunities as her journey in Westeros came to an end.
Following her time on *House of the Dragon*, Alcock featured in Netflix’s series *Sirens* and made her initial foray into the DC Universe towards the end of *Superman*, where she was introduced as Superman’s cousin alongside David Corenswet. This transition from a fantasy epic to a superhero film marks a significant milestone in her career.
*Supergirl*, directed by James Gunn, is touted as the second installment in the newly reimagined DC Universe. The film’s synopsis reveals that Alcock’s character embarks on an “epic, interstellar journey of vengeance and justice,” initially teaming up with an unexpected ally. This character-driven narrative promises to engage audiences and showcase Alcock’s range as an actress.
In discussing the potential challenges of her leading role, Alcock acknowledged the scrutiny women often face in the film industry. “We have become very comfortable having this weird ownership of women’s bodies,” she remarked. Her experiences on *House of the Dragon* have made her acutely aware of these societal perceptions, but she remains determined to stay true to herself amidst external commentary.
The anticipation for *Supergirl* builds as it gets closer to its release date, with a steady slate of DC Universe films confirmed for the future. Following *Supergirl*, audiences can look forward to *Clayface*, featuring Tom Rhys Harries, premiering on September 11. Additionally, a sequel titled *Man of Tomorrow* is set for release on July 9, 2027, though it remains uncertain whether Alcock will reprise her role in these upcoming projects.
Beyond her involvement in the DC Universe, Alcock is also gearing up for further collaborations in the film industry. She will be seen alongside Sofia Vergara and Kate McKinnon in the comedy *Thumb*, as well as sharing screen time with Toni Collette in *Hot Mother*. Alcock expressed her eagerness to work with “really cool young women” and highlighted fellow actress Rachel Sennott as particularly “f—ing fab.”
As fans await the release of *Supergirl*, Alcock’s journey from *House of the Dragon* to the DC Universe exemplifies her resilience and commitment to her craft. With her upcoming projects, it is clear that she is poised to make a significant impact in the entertainment industry, demonstrating her versatility and passion for acting.
