"Ms. Margot Robbie, who auditioned several times to win the part, worked with an acting coach to rid herself of her initial dislike of the character.

"She also met with the real-life inspiration for the character, a former model named Nadine Caridi, and other women who followed the same trajectory. “Had I not met them, I would’ve thought that the character I was doing in the film was so melodramatic and so unrealistic,” she said, “but then once I meet them it’s like, ‘Wow, I’m doing a dulled-down version of this.’”
