Supergirl film debut fuels hype, online harassment and modest box‑office outlook

DC Studios unveiled the first clip from its upcoming "Supergirl" movie, showing Kara Zor‑El (Milly Alcock) meeting her cousin Superman (David Corenswet) and humorously struggling with a language barrier. The film, directed by Craig Gillespie and produced by James Gunn and Peter Safran, also features Jason Momoa as Lobo and a supporting cast that includes Matthias Schoenaerts and Eve Ridley. It is slated to open in theaters on 26 June 2026, with advance screenings beginning 23 June.

Milly Alcock described her portrayal of Kara as a “perfect contrast” to Superman, emphasizing the character’s traumatic past and survivor instincts, a focus she says the script and direction highlight. Ahead of the release, Alcock disclosed receiving a large volume of toxic, gender‑based online comments, noting the difficulty of ignoring such harassment despite her familiarity with social media.

Industry analysts project the movie’s opening weekend at roughly $55 million, considerably lower than the $125 million debut of the 2025 "Superman" film. With a production budget of $175 million and substantial marketing costs, the film would need to generate around $315 million worldwide to break even, making its financial performance a key concern for Warner Bros.
