In Bombshell, Charlize Theron plays Megyn Kelly as she reaches a turning point in her cold war with Roger Ailes. The film which follows the unfolding scandal after anchor Gretchen Carlson (Nicole Kidman) accused the Fox News chairman of sexual harassment and filed a lawsuit against him in July 2016. Kelly finds herself stranded in the middle, unsure if she should speak out against Ailes, or wait on the sidelines until the dust settles.

In an exclusive clip, which you can see above, watch as Kelly reaches her breaking point when her team tells her about all the male anchors and commentators, like Sean Hannity and Brit Hume, who are publicly supporting Ailes. Then, she gets even more riled up when they tell her that those men wonder why no one uses the Fox News hotline, which employees can use to complain about potential harassment.

“It’s bullshit,” Kelly declares. “They have a contractual right to monitor our communications. A hotline in this building is like a complaint box in occupied Paris.”

She continues, on a tear now. “It’s like we’re telling women, Go on, speak up for yourself—just know the entire network is with Roger,” she adds. ‘“No one will believe you. They’ll call you a liar.”

Though Ailes denied the allegations, Carlson’s suit was settled two months later for $20 million. Ailes died the following May after falling at home and sustaining a head injury.

Theron does an eerily spot-on Kelly impression, aided by prosthetics designed by Kazuhiro Tsuji, the Oscar-winning artist who transformed Gary Oldman into Winston Churchill in Darkest Hour. “The quality of Kazu’s work was just so phenomenal,” Theron said in a recent interview with Deadline. She also noted, rather surprisingly, that the prosthetics needed one key element to make everything click into place: the eyelids.

“Whenever we applied everything but the eyelids, it never, ever felt right,” she said. “I looked like a young Glenn Close. It was bizarre.”

Theron has been stirring up Oscar buzz for her portrayal of Kelly, a polarizing figure who’s been embroiled in numerous controversies over the last few years (including insensitive remarks about blackface and Santa Claus). While on the circuit, Theron has been careful not to defend Kelly’s controversial comments, but has also made sure to applaud her for standing up to Ailes. “Up until four weeks into shooting, I was still grappling with who she was as a person, and it wasn’t until I really zeroed in on that year and a half of the story that I could actually defend her,” Theron told the New York Times .

“There are things she has said that I’ve definitely had issues with, but it doesn’t invalidate how I feel about her struggle,” she added.

Bombshell, directed by Jay Roach and written by Oscar winner Charles Randolph, will hit theaters on December 13.
