Supergirl: Woman of Tomorrow Gets New Update From Warner Bros. Discovery Boss

James Gunn and Peter Safran's DC Universe is on the horizon, with 2025's Superman: Legacy expected to reignite the modern DC franchise. Earlier this year, it was confirmed that the DCU has cast another of its flagship heroes, with House of the Dragon star Millie Alcock set to play Kara Zor-El / Supergirl. Alcock's Supergirl will star in her own live-action solo film, Supergirl: Woman of Tomorrow, which reportedly begins filming later this year. During Warner Bros. Discovery's recent quarterly earnings call, CEO David Zaslav very briefly commented on Supergirl: Woman of Tomorrow, and teased that other characters are being cast for the project.

"As I've said, we've really targeted DC," Zaslav explained. "We have Superman [and] Supergirl — great script has been written and that's being cast."

Who Is DC's Supergirl?

Created by Otto Binder and Al Plastino in 1959's Action Comics #252, Kara Zor-El is the cousin of Clark Kent / Superman, who is also sent to Earth from their dying home planet, Krypton. Shortly after her debut, Supergirl appeared in a backup strip in Action Comics, and became a public-facing superhero beginning in 1962. She made an array of comic appearances — including a 23-issue solo series — leading up to 1985's Crisis on Infinite Earths crossover, in which she was killed off in an effort to streamline continuity. The mantle of Supergirl was held by multiple women in the years to follow, including Linda Danvers, Cir-El, and eventually Kara herself when she was brought back to life in 2004. 

Supergirl has been portrayed onscreen a number of times over the years, across film, television, and animated projects. In live-action, she has been played by Helen Slater in the 1984 film Supergirl, Laura Vandervoort in later seasons of Smallville, Melissa Benoist on the Arrowverse's Supergirl television series, and Sasha Calle in last year's The Flash movie.

Who Is Writing Supergirl: Woman of Tomorrow?

Supergirl: Woman of Tomorrow does not have a release date or a director attached, but it has been confirmed that Ana Nogueira is writing the film's script. Nogueira was actually previously attached to write an earlier incarnation of a Supergirl movie, which would have starred Calle and spun directly out of the events of this year's The Flash movie. According to the reports, even though Nogueira's previous version of the movie was scrapped, Gunn and Safran liked her work and gave her an overall DC writing deal.

"A hearty public welcome to Ana Nogueira to the DC Studios family," Gunn stated on social media last year. "Ana is an amazing writer whose screenplay adaptation of Woman of Tomorrow is above and beyond anything I hoped it would be. We're excited to be moving forward on this unique take on Supergirl in this beautiful, star-spanning tale."
