Megyn Kelly last appeared on NBC more than a year ago, trying to contain an uproar over on-air remarks about blackface that ultimately brought her tenure at the network to an abrupt, unhappy end.

In a few weeks’ time, she will make a return — of sorts.

On Jan. 5, NBC will broadcast the 2020 Golden Globes, where Charlize Theron will walk the red carpet as a leading nominee for her portrayal of Ms. Kelly in the movie “Bombshell,” a dramatized account of the Fox News chairman Roger Ailes’s downfall that puts Ms. Kelly center stage.

Viewers will be treated to clips of Ms. Theron’s uncanny rendition of Ms. Kelly — the actress captures, with startling precision, the vocal tics and lawyerly cadences of the former Fox News anchor — in a performance that generated awards buzz even before the film opened on Friday in New York and Los Angeles. (Its wide release begins next Friday.)

But so far, Ms. Kelly has shown little interest in weighing in on her big-screen doppelgänger.

She did not participate in the making of the film — which was directed by Jay Roach from a script by Charles Randolph — and she and Ms. Theron have never spoken. Ms. Kelly attended a screening of “Bombshell” in New York last month, according to two people familiar with the event, but made no public remarks about it.
