James Gunn has added yet another DC Comics superhero to his upcoming Superman Legacy movie. Milly Alcock has been cast as Kara Zor-El AKA Supergirl (via Deadline).

She beat out Emilia Jones and Meg Donnelly for the role.

The cast for Superman Legacy currently includes Isabela Merced as Hawkgirl, Edi Gathegi as Mister Terrific and Nathan Fillion as Guy Gardner Green Lantern, Anthony Carrigan as archaeologist Rex Mason AKA Metamorpho, David Corenswet as Superman and Rachel Brosnahan as Lois Lane.

James Gunn, who will direct the 2025 movie, has previously already cast David Corenswet as Clark Kent and Rachel Brosnahan as Lois Lane. The movie will start shooting in January 2024.

Superman Legacy is slated to premiere on 11 July 2025.

According to Warner Bros’ official logline, Superman Legacy tells the story of Superman’s journey to reconcile his Kryptonian heritage with his human upbringing as Clark Kent of Smallville, Kansas. He is the embodiment of truth, justice and the American way, guided by human kindness in a world that sees kindness as old-fashioned.

Superman Legacy will be the first movie in the newly rebooted DCU or DC Universe. You can read more about that in detail by heading over here for my previous coverage.
