Margot Robbie’s “Barbie” movie casts Issa Rae, Hari Nef, Emma Mackey, Dua Lipa, Alexandra Shipp, Kate McKinnon and more as different iterations of the iconic Mattel doll, but the first actor Robbie envisioned as a Barbie in the film was none other than Wonder Woman herself, Gal Gadot. She wasn’t available, but Robbie explained to Vogue that Gadot’s “Barbie energy” became a template for casting all of the film’s Barbie roles.
