Sarah Snook

After four seasons of playing Siobhan "Shiv" Roy of the wealthy New York Roy family in HBO's Succession, Sarah Snook is now heading to the suburbs in All Her Fault. The series, created by Megan Gallagher, marks the Golden Globe and Emmy Award-winning actress' first starring TV role since Succession, which came to an end in 2023. Snook is also executive producing the forthcoming thriller from Universal Studio Group. Peacock announced the straight-to-series order for the project back in February of 2024.

Before Snook returns to the small screen, here is everything to know about All Her Fault.

What is the All Her Fault release date?

A premiere date has not yet been announced for the suburban-thriller series.

How to watch All Her Fault?

All Her Fault will stream on Peacock.

Who is in the cast of All Her Fault?

Snook has been cast to play the lead role of Marissa Irvine in the series. Stay tuned for casting announcements!

What is All Her Fault about?

According to Peacock, All Her Fault "opens on a plausibly terrifying situation that eventually unearths the deep secrets of a wealthy Chicago community." Snook's character Marissa arrives at 14 Arthur Avenue to pick up her young son Milo from his first playdate with a boy at his new school. However, "the woman who answers the door isn't a mother she recognizes. She isn't the nanny. She doesn't have Milo. And so begins every parent's worst nightmare."

Is All Her Fault based on a true story?

No, but if the story sounds familiar, it's because the series was adapted from Andrea Mara's 2021 novel of the same name.

The author, who is serving as an associate producer of the Peacock series, reacted Snook's casting news on Instagram, writing: "I wish I had a photo of my face when I heard this news – Sarah Snook, who played Shiv Roy in Succession, is to play Marissa in the screen adaptation of All Her Fault.(Obviously, I made a weird scrunched up cry face and screamed)."

Mara admitted that "the idea that a character I made up during one of my kid's occupational therapy appointments five years ago is being brought to life by actual @Sarah_Snook is insane."

She added, "And, bizarrely, last week I started writing my 2026 book and named the main character Siobhan, after Shiv, though I had no idea that's who was being lined up to play Marissa, so maybe this is how to manifest things 😄OK, back to screaming and scrunched up face here, and more news as I get it!"
