Actress Margot Robbie revealed that her “Suicide Squad” character, Harley Quinn, is not at all likable. In fact, her take on the iconic DC character might even be seen as “pretty vicious.”

According to Screen Rant, director David Ayer had a pretty specific vision for Robbie’s character. Ayer reportedly directed her into a “different style” while she was trying to interpret Harley Quinn for the big screen. “David really wanted her to be strong, badass and nuts…but fun as well,” the actress said in an interview published in Entertainment Weekly. “Whenever I would be inclined to play into the comedy or play her more likable, he’d always direct me the other way. He wanted her to be pretty vicious.”

Meanwhile, according to Batman News, some of Robbie’s co-stars also revealed how they prepared for their “Suicide Squad” roles. Cara Delevingne, who played Enchantress, said their director gave her an odd-sounding assignment to do. “David asked me to go into a forest under a full moon and take my clothes off to feel what nature felt like, to feel what it felt like to be an animal. And I did it,” she said. “It didn’t sound that weird to me.”

Karen Fukuhara, meanwhile, revealed she read the comic books before taking on the role of Katana. “I felt like I knew Katana as soon as I read the comic,” she said.

Emmy Award-winning actress Viola Davis also weighed in on her character. “‘How can I be a badass?’ I had to do it internally. Of course I wore my ‘fro. And I embraced her bio. That was all I had. I didn’t have a cape or a golden lasso. Davis played Amanda Waller, the character who came up with the idea to create the film’s titular squad.

“Suicide Squad” will hit theatres on August 5.
