Legendary Entertainment’s digital media unit and Fullscreen have teamed with YouTube creators Grace Helbig and Hannah Hart, who will star in a reboot of Sid and Marty Krofft’s ’70s campy superhero action TV series “Electra Woman and Dyna Girl.”

Fullscreen will debut the series in the U.S., with Legendary Television Distribution overseeing global distribution. Sid and Marty Krofft will exec produce the project.

The reboot of “Electra Woman and Dyna Girl” — starring Helbig as Electra Woman and Hart as Dyna Girl — follows the two superheroes as they move from Akron, Ohio, to Los Angeles in hopes of making it big in the crime-fighting world, only to find competition with other vigilantes and infighting among themselves.

Helbig and Hart have social-media followings with a combined total of more than 10 million subscribers and followers. The series also comes after Helbig and Hart’s 2014 digital feature film “Camp Takota,” which was exec produced by Helbig and Hart and produced by Fullscreen chief content officer Michael Goldfine. “Camp Takota,” written by and co-starring YouTuber Mamrie Hart (no relation to Hannah) was picked up by Netflix last year.

Helbig is creator and star of YouTube series “itsGrace” and “DailyGrace,” as well as the recently launched series “HeyUSA” for Condé Nast Entertainment. She is repped by WME and Bleecker Street Entertainment.

Hart created and stars in YouTube series “My Drunk Kitchen,” currently with more than 1.8 million subscribers, and she also co-produced, created and starred in “Hello, Harto,” a show and tour she launched to crowd-fund over $250,000 to distribute 100,000 pounds of food for local communities. She is repped by UTA and Sarah Weichel.
