The standalone Supergirl film, “Supergirl: Woman of Tomorrow,” does not currently have a release date, but was estimated by James Gunn to debut two years after “Superman Legacy.” That film is currently slated for July 11, 2025, so it seems odd to make a casting decision for a film that won’t arrive — at the earliest — for another three years. This has led many to believe that Supergirl (or at least a pre-suited Kara Zor-El) will make some sort of appearance in “Superman Legacy” as an introduction to the character.
This could be a brilliant way to connect the two characters and their respective films, because Gunn has already confirmed that “Supergirl: Woman of Tomorrow” was going to be dealing with some serious turmoil. “Superman was sent to Earth and he was raised by incredibly loving parents whereas Kara was in a piece of Krypton that was drifting away from the planet and lived there for the first 14 years of her life [in] a horrible situation in which she watched everyone around her die,” said Gunn. “So she’s a much harsher and more f***ed up Supergirl.” Given the absolute nightmare existence Alcock portrayed as Princess Rhaenyra on “House of the Dragon,” the character is in more than capable hands.
