Margot Robbie just dropped a wild Birds of Prey secret: Penguin was supposed to be the main villain until Matt Reeves claimed him for The Batman! She told Colin Farrell that Reeves basically said, 'Don’t use the Penguin, he’s mine.' So they switched to Black Mask instead. Now fans are debating who would’ve played Penguin if Reeves hadn’t stepped in. Imagine a Harley vs. Penguin showdown! #Entertainment #Movies #MargotRobbie
