Supergirl movie unveils first poster as DC confirms trailer arrives tomorrow

DC Studios has released the first official poster for Supergirl, revealing the bold tagline “Truth, Justice, Whatever”—a clear signal that this new big-screen version of Kara Zor-El will bring a sharper, more rebellious tone to the DC Universe.

Alongside the poster, the studio confirmed that the first Supergirl trailer will premiere tomorrow at 12 p.m. ET / 9 a.m. PT / 5 p.m. BST, intensifying fan anticipation ahead of the film’s 2026 release.

Another major reveal is the involvement of composer Ramin Djawadi (Game of Thrones), whose addition has sparked excitement among fans expecting a grand, emotional score.

Rumors continue to swirl about whether the trailer may compete with other major releases, including speculation around Avengers: Doomsday and Disney’s shifting trailer plans. Whatever the case, Supergirl is quickly becoming one of the most talked-about projects in the new DCU slate.

Starring Milly Alcock as Kara Zor-El, the film follows Supergirl as she embarks on a cosmic journey for her 21st birthday with Krypto the Superdog. Joined by Ruthye, a young woman seeking vengeance, Kara is pulled into a violent quest that forces her to confront her origins and define her own heroic path.

Directed by Craig Gillespie and written by Ana Nogueira, Supergirl arrives in theaters on June 26, 2026.
