Batgirl has been a Gotham staple in DC Comics lore since the late 1960s, with the original superheroine set up as Barbara Gordon, the daughter of Gotham Police Commissioner Jim Gordon. Rosario Dawson voiced Batgirl who had a prominent role in WB’s animated The Lego Batman Movie, which has grossed $293.1 million since its bow this February 10.

Warner Bros has another female-centric DC pic in the works in Gotham City Sirens, which will focus on the Harley Quinn character played by Margot Robbie in Suicide Squad. David Ayer, who helmed that pic, will also direct Sirens.
