Despite DC Studios co-CEO James Gunn calling The Flash "one of the greatest superhero movies ever made," he chose to drop Sasha Calle from the new DCU. He's since cast Milly Alcock as the title character in Supergirl: Woman of Tomorrow.
The news has been welcomed given what we saw from Alcock in House of the Dragon and, in an interview with Collider, Melissa Benoist - who played the Girl of Steel in The CW's Supergirl - shared her advice for the rising star.
"I think what always drove me while working on that show was the audience and who I knew I was making the show for," Benoist said. "Of course, I know that she is an iconic character that spans many generations of fans."
"[But] the people that I was making that show for while we were making it were young women, and if I kept that in the forefront of my mind, it always made everything palatable."
When Benoist was cast in the Arrowverse, she was best known for starring in Glee. Her role in that series was a stark contrast to playing a superhero, but it still helped prepare the actress for Supergirl.
"What I learned on Glee was that I was a really hard worker and that I could do really hard things because the schedule on that show was grueling because there were so many moving parts. It was fun but tough. I'm sure if you've had anyone else from the show on here, they've said the same thing."
"You had to rehearse the dances, you had to prerecord the songs, then you had to film the songs, and filming the songs were a lot longer — they took hours and hours and hours — and then you also had the scene work. Then I knew that Supergirl was going to carry a lot of pressure , and the responsibilities were going to be immense. I think that my experience on Glee gave me the belief that I had the ability to carry Supergirl."
Benoist was the third person to play Supergirl in live-action. The first was Helen Slater in 1984's Supergirl movie (where she was portrayed as the cousin of Christopher Reeve's Superman) with Laura Vandervoort up next in Smallville. Benoist then followed and Calle came next in The Flash.
There had been tentative plans for her to headline a spin-off, though those were ultimately scrapped by DC Studios.
Now, it will be up to Alcock to put her spin on the iconic comic book character when Supergirl: Woman of Tomorrow is released in theaters on June 26, 2026.
