Who is playing Supergirl?

  • Milly Alcock has been cast as Kara Zor‑El / Supergirl in DC’s new Supergirl movie, currently slated for a 2026 theatrical release.
  • She is best known for her breakthrough role as young Rhaenyra Targaryen in House of the Dragon , which helped put her on the radar of DC Studios.

Project details

  • The film is commonly referred to as Supergirl or Supergirl: Woman of Tomorrow and is part of James Gunn’s revamped DC Universe slate.
  • It is directed by Craig Gillespie and written by Ana Nogueira, with James Gunn and Peter Safran producing.

Character and tone

  • This version of Supergirl is described as more hardened and jaded than Superman, having grown up on a fragment of Krypton and witnessed enormous loss before coming to Earth.
  • Creators have called her an “antihero” with “edge, grace, and authenticity,” signaling a rougher, more cosmic, revenge-driven story than traditional Superman tales.

Other current Supergirl portrayals

  • For context, Melissa Benoist previously played Kara Danvers / Supergirl in the CW TV series Supergirl (2015–2021), but that show has concluded and is separate from the new DCU film.
  • The 2026 movie is a fresh continuity and does not continue the CW storyline, even though it draws on classic DC Comics material.
