Today it has been confirmed that DC Studios’ second theatrical release, Supergirl, will make its global streaming debut exclusively on HBO Max on September 10, 2026.
In its inaugural flight into the new DC Cinematic Universe, SUPERGIRL reveals the origin of the interplanetary nomad Kara Zor-El, aka Supergirl, cousin of Kal-El, better known as Superman. Headstrong, worldly-wise, and often reckless, Supergirl exudes a brand of heroism all her own—truthful, relatable, and always on her own terms. But when an unexpected and ruthless adversary strikes too close to home, Kara reluctantly joins forces with an unlikely companion. Together they undertake an epic, interstellar journey, struggling to balance one’s need for vengeance with the pursuit of justice—and to save the life of Kara’s best friend, her dog Krypto. Ultimately Supergirl will prove that doing good can be tough… and it doesn’t always have to be nice.

In our four star review of the film Neil says “Supergirl is a phenomenally fun time at the movies, anchored by an incredible performance from Milly Alcock. The film breaks new ground by taking DC’s characters out into space, widening the scope of the burgeoning DCU infinitely. With an outstanding mix of practical effects, huge fights and fun needle drops it’s easily the perfect film to kick off summer 2026.”
