Nicole Kidman, the superstar who has starred in shows like Big Little Lies, has joined Pen15 co-creator Maya Erskine's limited series thriller based on the novel The Nanny Killer at HBO.

According to Deadline, Kidman and Erskine will co-star and executive produce, while the latter will also act as the writer and creator of the show. The thriller will be based on the book of the same name by Leïla Slimani.

The premise of the book, which was inspired by real events, sees a seemingly perfect nanny who works for a couple with two young children, but her helpful personality eventually deteriorates into something sinister.

This is not the only show Kidman has in the works. She is also going to star in Yellowstone creator Taylor Sheridan's upcoming series called Lionness. She will also executive produce this show.

Based on a real-life CIA operation, the show's premise centres on "rough-around-the-edges but passionate" young marine Cruz Manuelos (played by Laysla De Oliveira), who's brought into the Lioness Engagement Team to help wipe out a terrorist organisation.

Kidman will play Kaitlyn Meade, "the CIA's Senior Supervisor who has had a long career of playing the politics game."

The synopsis continues: "She must juggle the trappings of being a woman in the high-ranking intelligence community, a wife that longs for the attention she herself can't even give, and a mentor to someone veering suspiciously close to the same rocky road she's found herself on.

"

As for Big Little Lies, her co-star Zoe Kravitz has given the unfortunate update that the show will likely not go on.

Speaking on a Q&A hosted by GQ in 2022, Kravitz said: "I don't think it is. We talked about doing a season 3 a lot and, unfortunately, Jean-Marc Vallée, our incredible director, passed away this last year and I just can't imagine going on without him.

"He really was the visionary for that show. So, unfortunately, it's done," she added.
