The Batgirl solo feature would be part of Warner Bros.’ DC Extended Universe, and would feature other characters from the world of Gotham. No other producers are currently attached to the project, but Warner Bros. Picture Group’s Toby Emmerich is overseeing the project with Geoff Johns and Jon Berg.

This would be Batgirl’s first solo movie project, though she has played a supporting role in TV’s Batman  and Birds of Prey, as well as appearing in 1997’s Batman & Robin. Bat-Girl was first introduced by Bill Finger and Sheldon Moldoff as the character Betty Kane in 1961. However, she was replaced by Barbara Gordon, daughter of Gotham City police commissioner Jim Gordon, in 1967.

Whedon directed Marvel’s The Avengers and The Avengers: Age of Ultron, as well as having writing credits on both films. He also has writing and directing credit on Marvel’s Agents of S.H.I.E.L.D. pilot. He created the TV shows Buffy the Vampire Slayer, Firefly, Angel, and Dollhouse.
