Speaking to Vogue, Robbie said, "She doesn't even have superpowers...She's just a psychopath who runs around gleefully killing people-she finds joy in causing mayhem, which makes her weirdly endearing and fun to watch."

On Robbie's ability to play the character, director David Ayer said the role "...[demands] a lot of heavy lifting for an actor. But [Robbie's] a tough girl, and she's incredibly smart and mature beyond her years. She has ridiculous depth, and she's never been coddled, so she's very physically courageous. The things she was doing herself as far as stunts, you wouldn't believe. There's only a handful of actors who do that sort of work themselves."
