The Full Cast of Bombshell: Nicole Kidman, Margot Robbie, and More

The Big Little Lies star plays Gretchen Carlson, who was among the first to publicize Roger Ailes's sexual harassment.

In addition to starring in the upcoming Birds of Prey, Robbie will appear in Bombshell as a fictional character named Kayla Pospisil.

Atomic Blonde's Charlize Theron will portray Megyn Kelly, who has said she "could do worse" regarding Theron's casting.

Late Night's John Lithgow is playing the late, disgraced Roger Ailes, the villainous chairman of the network who died in 2017.

We don't know much about SNL alum Kate McKinnon's character, listed as Jess Carr, but judging from the trailer, she's a production assistant type working in the Fox News office who shows Robbie's Kayla the ropes.

Alice Eve (Black Mirror, She's Out of My League) is playing Fox News television personality and author Ainsley Earhardt, who's the cohost of Fox & Friends.

The name of The Good Place actress's character has yet to be disclosed, but it seems she works in the Fox News office with Kayla and Jess.

Legally Blonde alum Alanna Ubach is stepping into the shoes of conservative TV figure Jeanine Pirro, who is currently the host of Fox News Channel's Justice With Judge Jeanine.

Oscar winner Allison Janney plays Susan Estrich, a lawyer and professor who became the legal counsel to Ailes in 2016.

Ailes's wife Beth was played by Sienna Miller (in heavy prosthetics) in The Loudest Voice, but now Connie Britton is taking over in Bombshell. We've yet to glimpse the actress in character, but we already have a feeling she'll nail it.
