After captivating audiences as the sharp, complex Shiv Roy in HBO's Succession, Emmy and Golden Globe winner Sarah Snook is back on our screens, and she's jumping straight into another high-stakes, emotionally charged role. Forget the corporate backstabbing; this time, it's personal. Snook leads the cast of Peacock's upcoming psychological thriller, All Her Fault, a series that promises to keep you on the edge of your seat and deeply unsettled, especially if you're a parent.
The premise alone is enough to send shivers down your spine: a mother goes to pick up her son from a playdate, only to find the woman who answers the door has never heard of him. Sound terrifying? It absolutely is. The recently released trailer has already sparked a frenzy online, with viewers calling it "chilly" and "heart-dropping." It's clear that Snook, alongside a phenomenal ensemble cast including Dakota Fanning and Michael Peña, is delivering a truly gripping experience.
The Chilling Premise: Unraveling a Seemingly Perfect Life

The core of All Her Fault centers on Marissa Irvine (played by Snook). When she arrives to collect her young son, Milo (Duke McCloud), from what should have been a routine first playdate, her world instantly shatters. The woman who opens the door isn't a familiar face, and worse, she claims she doesn't have Milo and has no idea who he is. It's truly "every parent's worst nightmare," as the show's logline chillingly describes.
What begins as a frantic search quickly spirals into a complex investigation, led by a detective portrayed by Michael Peña. As secrets unravel, Marissa finds herself under intense scrutiny and judgment, not just from strangers but from her own family. The series teases that "new questions lead to deep secrets, revealing cracks in the Irvine's seemingly perfect world until everything is left shattered." The detective's ominous line in the trailer – "I honestly didn't see this coming—these nice people, killing each other" – hints at a far darker, more personal truth hiding beneath the surface, suggesting the culprit might be someone from Marissa's own trusted inner circle.
From Bestseller to Screen: The Creative Minds Behind the Thriller

This eight-episode limited series is an adaptation of Andrea Mara's bestselling 2021 novel of the same name. Mara herself serves as an associate producer, ensuring the essence of her gripping story is faithfully translated to the screen. Megan Gallagher, known for her work on the BBC's Wolf and Apple TV+'s Suspicion, adapted the novel and serves as the series' writer, creator, and executive producer.
The series, though primarily set in Chicago, notably took its production to Melbourne, Australia, marking a special homecoming for its lead star. This blend of international talent and localized filming brings a fresh perspective to the psychological thriller genre. Behind the camera, the directorial duties are split between two accomplished names: Minkie Spiro, celebrated for her work on 3 Body Problem and Pieces of Her, directed the first half of the season, while Kate Dennis, who helmed episodes of The Handmaid's Tale and GLOW, took the reins for the second half. This division of creative vision promises a dynamic and consistent storytelling approach.

Sarah Snook's Deep Dive into Motherhood and Twisted Tales

For Sarah Snook, taking on the role of Marissa Irvine was a unique and profoundly personal experience, especially as she recently welcomed a daughter of her own. She shared insights into how motherhood has impacted her approach to this heartbreaking story.
"To be pregnant in one show and then have your child go missing in the other—let’s hope that’s not the motherhood journey for most," Snook joked in an interview with Vanity Fair. "There’s a different kind of attention to those roles that I can bring now from being a mom, and also a depth of feeling that I wouldn’t have understood prior to having a kid. Thinking back on other shows where I’ve been a mom, [I’m] going, ‘Oh no, I don’t want to watch that because I would’ve made different choices if I was actually a parent.'"
Snook also expressed that she was drawn to the series because of "a real gift of a twist" embedded within the story, hinting at the complex layers and unexpected turns viewers can expect. This level of personal investment, combined with her unparalleled acting talent, promises to make Marissa's anguish and determination incredibly real and resonant for audiences.
