The cast for the upcoming first film in the new James Gunn-led DCU, Superman: Legacy, is really shaping up to be something special, and that feeling is just growing as a new announcement has been made that House of the Dragon‘s Milly Alcock has been cast as Supergirl.
Rumors have been floating around in recent weeks about possible choices for this role, and Alcock’s name has consistently been in the mix. It’s been reported that the final round of screen tests came down to her and Meg Donnelly, who actually voiced Supergirl in the recent DC animated movies Legion of Superheroes and Justice League: Crisis on Infinite Earths Part One. Many assumed this would give Donnelly an advantage in scoring this role.
Supergirl is set to make her debut in Superman: Legacy and then go on to star in her own solo film, Supergirl: World of Tomorrow, so we’ll definitely be seeing more of Alcock sooner rather than later.
Milly Alcock will be joining a wonderful cast for Superman: Legacy, including David Corenswet as Superman, Rachel Brosnahan as Lois Lane, Isabela Merced as Hawkgirl, Edi Gathegi as Mister Terrific, Nathan Fillion as Guy Gardner, Anthony Carrigan as Metamorpho, Skyler Gisondo as Jimmy Olsen, Nicholas Hoult as Lex Luthor, Sara Sampaio as Eve Teschmacher, and María Gabriela de Faría as the Engineer.
No official synopsis has been released yet, and James Gunn has said that filming will begin next month, so stay tuned for more news!
Superman: Legacy will hit theaters on July 11, 2025.
