Milly Alcock’s casting as DC’s Supergirl in the new phase of the franchise has taken the internet by storm. Not only because she was beloved by the fans in her performance in House of Dragon, but also because of just how believable the casting had been. This version of the iconic character has been attracting more than a little attention, causing many to get curious as to what the billion-dollar franchise will do with her, now that they are trying to do things differently.

James Gunn seems to have hinted at exactly this during a recent interview. The co-CEO of DC talked about what Superman: Legacy will bring, as well as the project that will come out from it, which is of course Alcock’s Supergirl movie, Supergirl: Woman of Tomorrow.

What Will Milly Alcock’s Supergirl Bring?

James Gunn recently did an interview with Variety, where he talked about the new version of Supergirl and what fans can expect from her. He stated that there would be one key feature of Supergirl: Woman of Tomorrow that would make it different from Superman: Legacy; the films would juxtapose each other. While the David Corenswet movie will be a classic tale of Superman, growing up and falling in love with humanity, the Kara Zor-El film will showcase her own story, which happens to be a lot darker.

“We see the difference between Superman, who was sent to Earth and raised by loving parents from the time he was an infant, versus Supergirl, who was raised on a rock chip off of Krypton, and watched everyone around her die and be killed in terrible ways for the first 14 years of her life,” 

Supergirl: Woman of Tomorrow will feature the story of Milly Alcock’s character through her journey through the universe during the first fourteen years of her life, witnessing the death of many along the way. This would naturally force the film to adopt a much darker tone compared to the Corenswet movie. Since the new Superman movie is famously going to be the opposite of Man of Steel, it can also be assumed that it will follow a similar, darker tone to the Henry Cavill film.

Milly Alcock Did Not Get Cast As Supergirl Because of House of Dragon

James Gunn also revealed the reason for Milly Alcock’s casting in an Instagram post. There were several questions that were raised when the news was announced. Many were wondering if the reason why the actress was cast in the role was because of her connection with Warner Bros, having starred in HBO’s House of Dragon.

“Milly is a fantastically talented young actor, and I’m incredibly excited about her being a part of the DCU,” Gunn said. “Yes, I first became aware of her in House of the Dragon but I was blown away by her varied auditions and screen tests for Supergirl.”

Gunn stated that though he got to know the actress through her work in the hit series, the reason for her casting was not only dependent on it. This, of course, could not have been the only reason why Alcock was cast here, as a role as iconic as this would have had an extremely thorough and lengthy process.
