If they want a huge hit for Robbie like others said GCS is a no brainer and the only way, 3 rebellion iconic CBM characters that mainstream recognize, cast Ana de arm as as PI, pair with 2016 type marketing blitz, Batman/Batgirl cameos, some proven director who can go nuts with a successful screenwriter, doesn’t have to be female but definitely have female input into the work, something that replicate the energy between Vaugn, Millar and Goldman for their work on Kick Ass and Kingsman would be an unanimous hit
Have Two Face as the villain, or Joker, someone GA likes, not sure if Leto would just be an auto turn off today. Talia as henchman or something. And definitely stop the cast from promoting it as a feminist film or along that line, boy that killed BOP, I liked it but I know people who never miss CBM just passed and the box office and narrative became a cat fight between the Depp and Heard crowds. Avoid that bomb please
