Supergirl, starring Milly Alcock, will make its global streaming debut on HBO Max on September 10.

DC Studios' Supergirl is slated for its global streaming premiere exclusively on HBO Max on September 10. This highly anticipated film will also be available on HBO linear two days later, on September 12, at 8:00 p.m. ET, bringing the latest iteration of the iconic hero to viewers.

The film boasts a compelling cast, featuring Milly Alcock in the titular role, alongside Matthias Schoenaerts, Eve Ridley, David Krumholtz, and Emily Beecham. Noteworthy appearances include David Corenswet and Jason Momoa, adding depth to the ensemble. The creative team behind the camera includes writer Ana Nogueira and director Craig Gillespie, known for their distinctive storytelling.

Supergirl embarks on its inaugural flight into the new DC Cinematic Universe by exploring the origin of Kara Zor-El, Superman's cousin. The narrative portrays Kara as a headstrong, worldly-wise, and often reckless hero, defining her own brand of heroism. Her journey sees her reluctantly joining forces with an unexpected companion to confront a ruthless adversary.

Their epic interstellar journey forces them to navigate the complex balance between vengeance and justice, all while striving to save Kara's best friend, her dog Krypto. The film aims to illustrate that doing good can be challenging and does not always necessitate a gentle approach, offering a nuanced take on heroism.

In a commitment to accessibility, an American Sign Language (ASL) version of Supergirl will also stream exclusively on HBO Max on the same day. This version is performed by Catalene Sacchetti and directed by Jonaz McMillan. The film was produced by DC Studios heads Peter Safran and James Gunn, with executive production by Nigel Gostelow, Chantal Nong Vo, and Lars P. Winther.
