HBO has cast Nicole Kidman and Maya Erskine in the adaption of The Perfect Nanny by Leila Slimani, Deadline has reported. The limited series will be led by the two, who will also executive produce the series. Erskine, best known for being the co-creator of Pen15, is the creator and writer of the adaption of the same name as the novel.

The novel was published in 2016 in France. Inspired by the 2012 Krim children murders, the story follows a seemingly stable and hardworking nanny who is working for a couple with two young children. As time goes on, her personality starts to shed and reveal something darker lurking behind her cheery smile. Although Nicole Kidman and Maya Erskine will star as the leads in The Perfect Nanny, their roles are currently unknown.

The two leads will executive produce with Per Saari, Pascal Caucheteux, and Philippe Godeau.
