Who plays supergirl in the 2026 movie?

I am not aware of any confirmed casting announcement for Supergirl in a film scheduled for 2026. The available public records do not list a specific actress for that role in a 2026 release. Consequently, I cannot provide a reliable name at this time. If you want the most up‑to‑date information, checking official studio press releases, reputable entertainment news outlets, or the film’s official website would be advisable. Until a credible source confirms the casting, any name you encounter online remains unverified.
