YouTube stars Grace Helbig and Hannah Hart have been cast in a reboot of the 1970s kids' show Electra Woman and Dyna Girl. Legendary Digital Media and Fullscreen are the companies behind the update of Sid and Marty Krofft's classic series, reports The Hollywood Reporter.

Electra Woman and Dyna Girl first appeared as part of The Krofft Supershow for one season in 1976. The story follows a pair of superheroes from Akron, Ohio who head to Los Angeles with dreams of becoming big time crime-fighters. In 2001, the WB attempted to revive the show, getting as far as shooting a pilot that never made it to series.

Music video director Chris Marrs Piliero (The Black Keys' "Tighten Up" and "Howlin' For You", Ariana Grande and Zedd's "Break Free") will helm the series with Tim Carter and Thomas Harlan producing. Helbig and Hart will executive produce alongside their managers, Ken Treusch and Sarah Weichel, respectively.

Greg Siegel, senior vp of development and production at LDM, said, "Legendary is no stranger to the world of superheroes and we're excited that Sid & Marty Krofft's Electra Woman and Dyna Girl will mark the first female crime-fighting duo for our brand... I look forward to seeing how Grace and Hannah bring these caped crusaders back to life." Fullscreen CEO George Strompolos added, "This is basically our plot to break the Internet in 2015. As we continue to expand our premium content strategy, we're extremely proud to collaborate with such great partners and can't wait to bring this amazing concept to fans everywhere."

Electra Woman and Dyna Girl is shooting now in Canada, though no release date has been revealed.
