The Peacock series All Her Fault, headlined by Sarah Snook, has rounded out its main cast by adding Daniel Monks, Duke McCloud and Kartiah Vergara. The series, based on a best-selling novel of the same name by Andrea Mara, also stars Dakota Fanning and Abby Elliot in prominent roles. 

Monks, McCloud and Vergara will play Brian, Milo and Ana respectively in the series. While Fanning plays Jenny, Elliot will essay the role of Lia. As previously announced, Snook takes on the role of Marissa Irvine. Touted to be a "suburban-thriller series", the cast also stars Jake Lacy, Sophia Lillis and Michael Peña in pivotal roles as Peter, Carrie and Detective McConville respectively.

All Her Fault revolves around Marissa Irvine who experiences every parent's worst nightmare when she goes to pick up her son Milo from his first playdate. However, the woman who answers the door is unfamiliar and doesn't have Milo.
