The movie follows the true story of Fox News anchor Megyn Kelly (Theron), who made sexual harassment allegations against Fox News’ late chairman, Roger Ailes (John Lithgow), in her memoir Settle For More. Kidman stars as fellow Fox News presenter Gretchen Carlson, who also filed a lawsuit against Ailes. Robbie’s role – ambitious young Fox News producer, Kayla Pospisil, who falls prey to Ailes – is fictional.

In a cover interview with Variety, Robbie has explained how she prepared for the role, which included a covert dive into the murky depths of Twitter.
