Warner Bros. and DC Studios have released the highly anticipated teaser trailer for ‘Supergirl,’ offering fans a thrilling glimpse into the cinematic rebirth of the iconic Kryptonian hero. The film stars ‘House of the Dragon’ breakout Milly Alcock in the dual role of Kara Zor-El/Supergirl, marking her first major foray into the DC Universe.

The trailer sets the tone for a darker, more emotionally charged chapter in the DC slate as Kara Zor-El faces an unexpected and ruthless adversary who strikes dangerously close to home. Forced out of isolation and into action, Kara reluctantly partners with an unlikely ally for an epic, interstellar mission driven by vengeance, justice, and the search for her own identity.

Alcock leads an impressive ensemble that includes Matthias Schoenaerts, Eve Ridley, David Krumholtz, Emily Beecham, and Jason Momoa under the direction of Craig Gillespie (I, Tonya, Cruella).

Written by Ana Nogueira, the film is produced by DC Studios heads Peter Safran and James Gunn, and is based on characters created by Jerry Siegel and Joe Shuster.
