Nicole Kidman and Margot Robbie also star in the film about the Roger Ailes sexual harassment scandal at Fox News.
The former Fox News host's bad marriage with NBC News is officially over with a big payout.

"I can be Doc Brown, and I wear the outfit and wig and not change my skin color," the "Today" host said.

Kelly drew backlash in recent days over comments defending "blackface."
The former NBC host is living her "best life" and is partnering with ABC for a new show.
NBC aired a rerun of "Megyn Kelly Today" on Thursday following backlash over the host's blackface comments.
The "Today" host defended blackface this week, after years of stirring up controversy on Fox News.
The "Today" show host said his NBC colleague should apologize for defending blackface Halloween costumes. Later, Kelly did just that.
The NBC host faced backlash after questioning what was racist about white people darkening their skin for Halloween costumes.
"We're people, not costumes," writer Amber Ruffin explained.
“Sometimes you say stupid things when you’re live, but I’m just going to be honest," the CNN host said.
"What is racist?" the "Today" show host asked an all-white panel.
"So long as you were dressing up as a character," she said.
