First 'Supergirl' Trailer Launches, Showcasing DCU’s Grittier, Spacefaring Take

The Craig Gillespie film positions Milly Alcock’s Kara as a rougher, outer-space anti-hero ahead of a June 26, 2026 release.

Overview

  • DC unveiled the first Supergirl trailer with an in-person New York watch party featuring James Gunn, Craig Gillespie and star Milly Alcock.
  • Filmmakers stress a sharp tonal break from Superman, with Gillespie saying the story unfolds entirely in outer space and Alcock describing a very different Kara.
  • The official synopsis and footage point to a reluctant team-up on a cosmic quest where revenge and justice collide, with Krypto the Superdog in the mix.
  • The cast includes Eve Ridley as Ruthye and Matthias Schoenaerts as Krem, with Jason Momoa confirmed as Lobo; Gillespie directs from Ana Nogueira’s adaptation of Tom King’s Woman of Tomorrow, and Ramin Djawadi is composing.
  • Marketing leading into today’s debut included a poster tagged “Truth. Justice. Whatever” and a 15‑second teaser from Gunn, and some outlets note unconfirmed chatter about a Superman appearance that remains a rumor.
