Stargirl live-action series coming to DC Universe

The future lineup of the DC Universe streaming service is continuing to expand with a live-action Stargirl series on the way from writer Geoff Johns.

Johns unveiled the 13-episode series at San Diego Comic-Con, according to io9The show will follow the character of Courtney Whitmore, a character Johns created with James Johnson, Lee Moder, and Chris Weston in 1999.

The series will follow the adventures of Stargirl as she helps to form the Justice Society of America, the first superhero team in the DC Comics (or any comics) universe. Johns will work on the show as a writer and executive producer.

This isn't the first time the character has made an appearance on screen, with a version of Stargirl previously showing up on the CW's Legends of Tomorrow during its second season as one of the members of the JSA. She also appeared in Smallville

While the production has yet to cast its Courtney, Johns did say that the Stargirl version of Stargirl will be reimagined as a younger woman than her previous iterations, which would seem to suggest that Sarah Grey, who played the character on Legends of Tomorrow, is unlikely to be reprising the role in the new series.

Johns recently left his post as the president of DC Entertainment in an executive shakeup at the company, which is reportedly in the middle of reevaluating the direction of its film franchise. The development appears to have left Johns — who started his entertainment career as a comic book writer — with more freedom to directly develop projects rather than oversee the broad picture of DC Comics properties on screen. In addition to Stargirl, he's also one of the developers behind Titanswhich is set to be a debut series for the DC Universe service.

No release date has yet been announced for Stargirl. The platform it will air on, DC Universe, is expected to launch sometime this fall.
