Margot Robbie has revealed that the Penguin was initially set to be the main villain in Birds of Prey, before Matt Reeves decided to use him for The Batman.
"The first draft that Christina [Hodson] wrote of Birds of Prey, the villain was the Penguin," Robbie told Colin Farrell during an interview with Entertainment Weekly. The actor went on to explain to a shocked Farrell that it was ultimately Reeves who barred the film from including the Penguin. It's worth noting, however, that Farrell wasn't cast as Oz Cobblepot aka the Penguin until Birds of Prey had already entered post-production (and we're curious as to who Hodson and director Cathy Yan had in mind at the time).
