James Gunn Casts Doubt on Supergirl Being in ‘Superman: Legacy’ – “I Never Even Said She Was in the Movie”

Following the release of ‘Aquaman and the Lost Kingdom’ DCEU is officially over and Gunn’s DCU is ready to take over the reins as the next big cinematic universe featuring DC’s characters. ‘Creature Commandos’ is the first project to be released as a part of DCU, but both Gunn and Safran confirmed that the true beginning is ‘Superman: Legacy.’

Gunn frequently reveals information regarding the development of his so-far favorite projects. He often clears up some details regarding the production of the movie. He cleared up that the development so far is going “swimmingly” as sets are being built, costumes are finished, and actors are adjusting to their roles. One fan took the opportunity to ask Gunn how much the cast he has locked in for ‘Legacy,’ and Gunn was vague in answering but confirmed that it’s more than 90 % but less than 100%, meaning that not all characters have actors attached to them, which will consequently start more rumors.

Just a few days ago confirmation came that Milly Alcock will be playing Superman’s cousin Supergirl. The extent of Supergirl’s role remains unknown at the moment since little is known about the overall plot of the movie, except for the fact that it’s going to be an origin story focused on Superman. However, since Supergirl’s own movie is in the making called ‘Supergirl: Woman of Tomorrow,’ we can assume that Milly is here in the long run, ready to reprise her role in every DCU project.

Recently a fan asked Gunn on Threads how much screen time Milly Alcock will have in ‘Superman: Legacy’ and Gunn answered in a pretty vague way, confirming that he never actually cleared up on whether Kara will appear in the movie in the first place.

Gunn most likely is trying to keep the mystery surrounding the movie for as long as possible, but realistically Supergirl will most likely make an appearance in the movie, however small. Otherwise, there is no logic in casting the actress so quickly, without a writer, script, or story attached to her own standalone movie. In any case, all will be revealed when the movie is fully released.

The upcoming film, ‘Superman: Legacy,’ directed by James Gunn and produced by Peter Safran is set to be released on July 11th, 2025. What do you think will Supergirl be in the movie? Let us know in the comments below!
