Sarah Snook & Dakota Fanning Star

Sarah Snook is living a parent’s worst nightmare come true in All Her Fault, Peacock’s upcoming series starring Snook and Dakota Fanning. The streamer dropped the first trailer today along with some additional first-look photos of the series based on Andrea Mara’s 2021 bestselling novel.

The trailer opens with Snook’s Marissa arriving to pick up her young son Milo (Duke McCloud) from his first playdate, but she does not recognize the woman who answers the door. The woman does not have Milo and has never heard of him. There’s no sign of Milo anywhere. 

“If anyone has any information, please, we beg you to come forward,” an emotionally distraught Marissa pleads at a news conference asking for the public’s help.

As the investigation unfolds, Marissa comes under intense scrutiny and judgment from family and strangers alike who seem to be blaming her. It later becomes clear that the culprit can only be someone from Marissa’s most trusted inner circle. As her entire life unravels, she swears “I will do whatever it takes to get my son back.”

Fanning stars as Marissa’s friend Jenny. Cast also includes Jake Lacy, Michael Peña, Abby Elliott, Daniel Monks, and Jay Ellis.

Megan Gallagher (Wolf) serves as writer, creator and executive producer. Minkie Spiro (3 Body Problem) directs the first episode, among others, and executive produces. EPs also include Nigel Marchant, Gareth Neame and Joanna Strevens for producer Carnival Films (The Day of the Jackal), Jennifer Gabler Rawlings and Christine Sacani, producer Terry Gould and associate producer, Andrea Mara, who wrote the novel All Her Fault. Universal International Studio, a division of Universal Studio Group, is the studio.

All Her Fault premieres on Peacock with all eight episodes November 6, 2025.
