Sarah Snook Stuns Viewers With Gripping Comeback in Peacock Thriller ‘All Her Fault’

Emmy-winning actress Sarah Snook has made her highly anticipated return to television with the Peacock thriller All Her Fault. The Australian star, known globally for her role as Shiv Roy in HBO’s Succession, steps into a new emotional territory as she portrays a mother caught in a tense kidnapping mystery. Premiering this week, the limited series marks Snook’s first major TV role since Succession concluded in 2023.

What the Series Is About

Adapted from Andrea Mara’s bestselling novel, All Her Fault follows Marissa Irvine, played by Sarah Snook, whose life unravels after she arrives to collect her son from a playdate—only to find him missing. Set in suburban Melbourne, the six-part drama explores themes of family trust, wealth, and deception.
The show was developed by Megan Gallagher and Nigel Marchant, with Snook also serving as an executive producer. The series blends psychological tension with social commentary, offering a layered look at privilege and parental fear.

What Sarah Snook Said

Speaking to TheWrap, Snook described the project as “too delicious to turn down,” despite initially planning a break after her West End performance of The Picture of Dorian Gray.

“They told me the premise, the plot, and the twist—and I knew I couldn’t say no,” Snook said.
She explained that Marissa was a “very warm, maternal” character—quite different from the icy corporate strategist she portrayed in Succession. Snook also shared that the role demanded “piano wire tension all the time,” given the high emotional stakes of the story.

Snook added that working with Dakota Fanning, who plays her friend Jenny, brought “a sense of safety and lightness” to the intense set. She also helped implement sustainability practices, including electric vehicles and zero-waste food operations, during production in Melbourne.

Why It Matters

Snook’s return to TV underscores her continued impact as one of Hollywood’s most versatile performers. After Succession ended with critical acclaim and multiple awards, her decision to take on All Her Fault positions her firmly in the psychological thriller genre.
The series also highlights Snook’s growing influence behind the camera, as she explores executive production and environmental responsibility within the industry.

What’s Next

While Snook is taking a short break from theater after Dorian Gray, she hinted at pursuing a “really good film with a great director” next—potentially a period drama. For now, All Her Fault is streaming exclusively on Peacock, with critics praising its emotional depth and Snook’s commanding performance.
