You have to give Warner and DC Comics credit for persistence. Deadline is reporting that the studio has a SUPERGIRL film in the works, with Oren Uziel (The Cloverfield Paradox) penning the script. No other details are available.
Supergirl’s comic book history is complicated, depending on which side of a reboot you’re on, but she’s generally accepted to be Superman’s cousin from Krypton. Supergirl first appeared in a story published in Action Comics #252 (way back in May 1959) imaginatively titled “The Supergirl from Krypton”.
Supergirl is, of course, currently a TV series from Greg Berlanti on the CW, having just completed its third season. Melissa Benoist plays the titular hero, with Tyler Hoechlin having appeared several times as Superman. It is understood this new film will fit into the DC Extended Universe and follow Man of Steel and Justice League.
Deadline points out what a change in direction this is for the franchise, one looking for a way to bring Superman back out of the darkness and into the pantheon of inspiring superheroes. It would certainly match the lighter tone that Shazam! and hopefully Wonder Woman 1984 is striving for.
The last Supergirl film was in 1984 starring Helen Slater. That actress has since cameoed in the Supergirl TV series, cleverly playing Supergirl’s adopted mother opposite former Lois & Clark alum Dean Cain.
