James Gunn’s DC Studios Supergirl Movie Casts Villain

Every superhero must have a supervillain to face off with—those are the rules!—and it sounds like Supergirl, as played by Milly Alcock (House of the Dragon) in the James Gunn-produced, Craig Gillespie-directed Supergirl movie coming summer 2026, has found her foe. And we know who’ll be playing him: Belgian actor Mattias Schoenaerts, whose many credits include 2020’s The Old Guard.

This news comes from Deadline; the trade—pointing to the fact that fans already know Supergirl will draw from the 2022 Tom King-Bilquis Evely comic series Supergirl: Woman of Tomorrow—adds the likely suggestion that Schoenaerts will be playing the same villain from that comic: Krem of the Yellow Hills, whose random killing of an alien girl’s father is what draws Supergirl into his orbit. That, and as the Hollywood Reporter further references, he shoots arrows at Supergirl and Krypto, injuring “everyone’s favorite superpet.”

As all devoted pet owners can understand, someone daring to harm a beloved animal companion automatically triggers what’s known as the John Wick reflex, so there’s no better impetus for bringing Kara Zor-El into the fight. (And as to Krypto’s fate, with noted dog lover Gunn involved, it seems entirely possible the pooch makes a full recovery—though let’s not forget not every adorable animal made it out of Guardians of the Galaxy Vol. 3 unscathed.)

Supergirl: Woman of Tomorrow is being scripted by Ana Nogueira (The Vampire Diaries, the upcoming live-action Teen Titans movie), with Gillespie (I, Tonya; Cruella) handling directing duties. It will be the second feature in the new Gunn and Peter Safran-led DC Studios era, following Gunn’s Superman, which arrives July 11, 2025. Supergirl, meanwhile, will hit theaters June 26, 2026.
