Robbie's performance in Suicide Squad as Harley Quinn is highly anticipated and easily one of the most hyped elements of the upcoming blockbuster. But in order to get her look right, Robbie went through many different costumes before settling on one.

"We tried on every variation of the costume. I cannot [emphasize] enough how many outfits, and how many variations of the Harley Quinn costume we tried," the actress told HelloGiggles.com recently. "We tried the court jester costume, we tried the corset and skirt, we tried leather pants, we tried literally every type of costume possible for her. I really love where we ended up. And who knows, maybe in the sequels we'll go with the court jester one. I think there's a world of possibilities."

What Is 'Suicide Squad' & Who Are Its Members?

As for her approach to performing as Harley Quinn, Robbie is not using the "method" approach, like Jared Leto and the late Heath Ledger used for playing The Joker.

"No, I'm not a method actor, I don't think anyone would still be friends with me if I were trying to be method with Harley," she said. "My best friend, who is my assistant, I don't think she'd put up with that!"

Robbie also noted that the entire ensemble, which includes Leto, Will Smith, Jai Courtney and more, gets their moment to shine in the film.

Suicide Squad is scheduled for release in theaters on Aug. 5.
