The story behind BOP script is nuts. Basically it’s a hodgepodge of recycled DC scripts from the WB graveyard that Margot Robbie got to pick n choose bits from. That included an abandoned suicide squad script where the team has to save Cassandra Cain from her assassin parents…
Rumors are that the only reason it’s taking so long is cuz they gave Ali a lotta control over the project kinda like Reynolds w Deadpool, and apparently he’s super picky and hard to please. Considering how fast it takes other MCU projects to turn around I’m inclined to believe it
