Milly Alcock Cast as Supergirl in James Gunn’s DCU

Supergirl Milly Alcock

Milly Alcock has emerged victorious out of the race for the Supergirl casting race, TheWrap reported on Monday night. The search for the actress to play the Woman of Steel in the upcoming DCU had ramped up in the past couple of weeks, and though it may have seemed obvious that Alcock was the odds-on favorite, it ain’t over until it’s over.

 

According to reports, three actresses were moving on to the screen test phase: Alcock, Meg Donnelly (who voiced the role in multiple DC animated projects), and Emilia Jones (CODA). Another story from The Hollywood Reporter last week said that Jones was no longer in the running, which perhaps suggested that she had taken herself out of the race. They also threw in another name that was once in contention: Cailee Spaeny, who was just in Sofia Coppola’s Priscilla and will lead this year’s Alien: Romulus.

 

Alcock’s Supergirl is going to be a part of Superman: Legacy, as suggested by several reports and also by the fact that the casting process is taking place now. The movie is to start shooting in Atlanta this spring. She is supposed to be a huge part of James Gunn’s DCU, even before her own movie takes flight a few years from now — Supergirl: Woman of Tomorrow. Playwright Ana Nogueira is scripting that movie, but no director has been attached yet.

 

Milly Alcock is already part of the Warner Bros. Discovery family, having played the lead in the first half of House of the Dragon as the younger version of Rhaenyra. Season 2 of the HBO series will be out this summer, and though there were conversations about bringing back the younger cast from those first five episodes for some flashbacks, there hasn’t been any confirmation on her return to Westeros.

 

Superman: Legacy will land in theaters on July 11, 2025.
