Sarah Snook returns to television in 'All Her Fault,' a Peacock limited series adapted from Andrea Mara's 2021 novel, where she plays a wealthy Chicago mother whose son is kidnapped. The eight-episode thriller explores themes of parenthood and class amid a frantic search for the missing child. All episodes are now streaming on Peacock.
Overview
'All Her Fault' follows Marissa Irvine (Sarah Snook), a self-made wealth manager in Chicago, as she discovers her 5-year-old son Milo (Duke McCloud) has vanished after a playdate. The series, created by Megan Gallagher and produced by Universal International Studios, delves into the family's unraveling as they investigate suspects including the nanny Carrie Finch (Sophia Lillis) and Marissa's acquaintances. Directed by Minkie Spiro and Kate Dennis, the show was filmed in Australia despite its Midwestern setting.
Cast and Plot Details
Snook executive produces and leads alongside Jake Lacy as her husband Peter, Dakota Fanning as friend Jenny, and Michael Peña as the lead detective. Supporting roles include Abby Elliott as Peter's sister Lia, Daniel Monks as brother Brian, Jay Ellis as Marissa's business partner Colin, Thomas Cocquerel as Jenny's husband Richie, and Kartiah Vergara as family nanny Ana. The narrative centers on buried family secrets, gender dynamics in marriage, and the anxieties of hiring childcare, drawing comparisons to thrillers like 'Big Little Lies' and 'The Hand That Rocks the Cradle.' No ransom demands complicate the search, forcing scrutiny of those closest to the Irvines.
Release and Context
Premiering two and a half years after 'Succession,' Snook's showcase role highlights her emotional range, though the series paces deliberately with twists in later episodes. It critiques working mothers' blame in crises but leaves some character backstories underdeveloped. The full season became available on Peacock on November 6, 2025, marking another entry in the affluent mystery genre.
