What is the original language of Supergirl (2026)?

The original language of Supergirl (2026) is English.

The film is an American production from DC Studios, directed by Craig Gillespie and written by Ana Nogueira. Its principal dialogue is classified as English, even though the story is set partly across alien worlds and includes Kryptonian and other fictional languages.

That distinction can cause confusion: a film may feature invented languages or brief dialogue in another language without changing its listed original language. Supergirl's cosmic setting is especially multilingual, with the production describing several worlds and distinct languages. Milly Alcock also filmed scenes with David Corenswet involving Kryptonian.

This movie is a new DC Universe interpretation of Kara Zor-El rather than a continuation of the 1984 Supergirl film or the television series. It adapts major ideas from Tom King and Bilquis Evely's comic miniseries Supergirl: Woman of Tomorrow and is scheduled for a June 26, 2026 theatrical release.
