Supergirl: Woman of Tomorrow Cast Breakdown
The Supergirl film stars Milly Alcock as Kara Zor-El, a jaded Kryptonian raised on a surviving fragment of Krypton, contrasting her cousin Superman's Earth-raised optimism. Alcock, known from House of the Dragon, was cast after a rigorous audition process involving 2,000 candidates, finalized by James Gunn on October 17, 2022. Her portrayal draws from Tom King's 2022 comic miniseries, emphasizing Supergirl's antihero edge, as Gunn described her as "pixie-ish but very attitudinal" in a July 2024 Variety interview.
Matthias Schoenaerts plays Krem of the Yellow Hills, the ruthless leader of the Brigands, space pirates responsible for killing Supergirl's father. The Belgian actor, with credits in The Old Guard (2020), brings intensity to the antagonist, whose human trafficking ring drives the plot. Schoenaerts bulked up 15 pounds for the role, training with Gunn's regimen that included 6 weeks of zero-gravity simulations starting March 2025.
