According to reports, Cathy Yan ("Dead Pigs") will direct the "Suicide Squad" spin-off "Birds of Prey", written by Christina Hodson, ("Batgirl") showcasing Margot Robbie as 'Harley Quinn':
Robbie's LuckyChap will produce with Sue Kroll, Kroll & Co Entertainment and Bryan Unkeless of Clubhouse Pictures.
Premise of "Birds of Prey", originated as a partnership between 'Black Canary' and 'Barbara Gordon', who adopted the codename 'Oracle' at the time, but has since expanded to include additional crime-fighting superheroines, based in 'Gotham City'.
