What Happened: Snook’s First Major Role Since Succession

“It’s very different from Shiv,” Snook explained at a press conference. “She’s internally cold and stiff. Marissa has warmth.” The actress drew inspiration from costuming choices to maintain that warmth even during the series’ tension-filled moments. The 8-episode limited series began streaming on Nov. 6 with all episodes available immediately to Peacock subscribers.
“Finding something different was really important. Succession was such a huge, zeitgeist moment. I can’t top that experience.”
The series reunites Snook with Jake Lacy as her husband Peter and features Dakota Fanning as family friend Jenny. Supporting cast includes Michael Peña, Sophia Lillis, Abby Elliott, and Jay Ellis. Directors Minkie Spiro and Kate Dennis helm the mystery with a female-centric vision.
Why This Matters: Motherhood Meets Mystery
Snook isn’t just acting in this mystery—she’s an executive producer shaping the story’s vision. Her own experience as a mother of a 2.5-year-old daughter deeply informed how she approached Marissa’s role. The actress married Australian comedian Dave Lawson in 2020 and became a parent in May 2023.
“There’s a lot reflected from my current state insofar as me working and trying to be a parent simultaneously,” Snook shared. “Marissa has the added stress of her husband also working and trying to create a career. It’s about balance and who’s more important in this moment—then a child goes missing.”
The series tackles the “invisible labor” women perform daily in relationships and households. When Marissa’s son vanishes, questions emerge about who’s responsible. The title itself becomes a commentary on societal blame cast on mothers. Snook worked with female showrunner Megan Gallagher and female directors intentionally to capture these nuances authentically. Such leadership ensures the themes land with deft precision rather than heavy-handedness.
The Details: A Thriller with Social Commentary
All Her Fault adapts Andrea Mara’s bestselling novel, but producers relocated the story from Ireland to Chicago‘s wealthy neighborhoods. When Marissa arrives to pick up her 5-year-old son Milo from a playdate, the woman answers the door claiming no playdate occurred. Milo has disappeared.

The mystery deepens as Marissa, Jenny, and Peter investigate Milo’s disappearance. Every character harbors secrets. The twist becomes increasingly complex as family dysfunction surfaces. Beyond the thriller mechanics, the show critiques the impossible balance working mothers face.
Snook credits the female-led creative team for executing these themes deftly. “You don’t want to be too on-the-nose. Otherwise, they’re overlooked. If you’re more deft, people who need to see those moments will think, ‘Oh, that’s a really good point.'” Showrunner Gallagher added: “Every woman I know working and raising children has breakdown crying fits outside their kids’ school.”
What To Watch For: Series Themes Beyond the Mystery
- How the series balances thriller pacing with social commentary about motherhood
- Snook’s chemistry with Fanning as two women navigating impossible situations
- The “invisible labor” theme—household tasks women absorb without recognition
- Whether wealthy surroundings shield or complicate Marissa’s crisis unfolding
- How blame gets displaced onto mothers in society—central to the show’s thesis
Critics have praised All Her Fault as a gripping mystery anchored by authentic performances. The Hollywood Reporter called it a “satisfying domestic mystery,” while NPR highlighted how the 8-part series examines the psychological toll of motherhood under pressure. Snook’s warmth counterbalances the thriller darkness, making her vulnerability real and compelling throughout.
Is Her Fault the Fresh Start Snook Needed After Succession?
Sarah Snook deliberately chose a project that differed drastically from Shiv Roy‘s cold ruthlessness. “I can’t top that experience, so finding something different was really important,” she explained. All Her Fault delivers exactly that—a complex mother grappling with modern parenting anxieties within a suspense framework.
As both actress and executive producer, Snook championed eco-friendly set practices during filming in Australia and Chicago. She pushed for reusable materials, electric vehicles, and sustainable production choices. This commitment to environmental responsibility mirrors her character’s care and intentionality as a mother.
The series resonates because it asks: When catastrophe strikes, how much responsibility lands on women? Snook’s Marissa responds with desperation, intelligence, and humanity. Will you stream All Her Fault on Peacock and explore how motherhood becomes the central mystery itself?
