Milly Alcock is stepping into one of the biggest roles of her career as Kara Zor-El in Supergirl. After gaining international attention as young Rhaenyra Targaryen in House of the Dragon, the Australian actress now faces the enormous expectations surrounding a major DC superhero.
Training for the Superhero Role
Alcock’s preparation went far beyond learning dialogue and understanding the character. She completed intensive physical training before filming, including stunt work at Leavesden Studios in the United Kingdom.
According to Variety’s interview with Milly Alcock, she spent two months preparing for the action-heavy role. Her training included learning how to throw punches, take hits, fall safely and perform increasingly complicated fight sequences.
Alcock also revealed in Teen Vogue’s behind-the-scenes character study that she trained for around two hours a day. The sessions gradually moved from basic movements to complete combat sequences with stunt performers.
Finding the Human Side of Kara Zor-El
Physical preparation was only part of Alcock’s transformation. The actress also focused heavily on understanding Kara’s emotional journey.
The new version of Supergirl draws significant inspiration from Tom King and Bilquis Evely’s acclaimed Supergirl: Woman of Tomorrow comic. Rather than portraying Kara as a flawless superhero, the story explores a young woman dealing with loss, anger and the complicated process of finding her purpose.
In DC’s official interview with Alcock and writer Ana Nogueira, the actress discussed the importance of connecting with Kara’s humanity. That emotional foundation could become one of the defining features of her performance.
A Very Different Supergirl
This interpretation of Kara is intentionally rougher around the edges. She is powerful, but she is also dealing with trauma and isolation. The character’s journey is about learning that being a hero is not simply about possessing extraordinary abilities.
Vanity Fair has highlighted the pressure surrounding Alcock’s casting and her transition from acclaimed television performer to the face of a major superhero franchise.
Alcock has also approached the role without attempting to imitate previous live-action Supergirls. In fact, she has acknowledged that she did not extensively study earlier superhero movies while preparing for the part.
From House of the Dragon to the DC Universe
The leap from House of the Dragon to Supergirl represents a dramatic change in scale. Alcock’s performance as young Rhaenyra established her as an international star, but Supergirl places her at the center of a major cinematic universe.
Her preparation has therefore involved physical discipline, character research and a willingness to embrace the pressure of leading a blockbuster. Alcock’s own account of the production process shows how demanding the combination of acting and stunt work became during filming.
Why Milly Alcock’s Supergirl Could Stand Out
The most interesting aspect of Alcock’s approach may be that she is not trying to make Kara simply look heroic. Instead, she is building a character who feels damaged, complicated and human before becoming inspirational.
That combination of physical preparation and emotional depth could make Alcock’s Supergirl very different from previous interpretations. The cape may be iconic, but her performance will ultimately depend on making audiences believe in the person underneath it.
For Milly Alcock, becoming Supergirl is more than accepting a superhero costume. It is the challenge of creating a new version of Kara Zor-El while carrying the expectations of one of DC’s most recognizable characters.
