Sarah Snook’s first major post-succession series kills Peacock

In the wake of her brilliant four-season run on the HBO hit “Succession,” Sarah Snook has done it again…and by “redone,” I mean she’s established herself as a major attraction on the small screen.

Snook’s relatively new Peacock original series, “All Her Fault,” according to an exclusive report from Variety, has racked up a frankly incredible 46 million hours watched in just three weeks – with the miniseries released on Peacock in its entirety on November 6, 2025 – and in doing so, the outlet reports that “All Her Fault” is now “the most-watched original series debut in the streamer’s history.” Not only that, but Variety also revealed that “All Her Fault” topped the streaming show charts overall during the same three-week period (during which it logged just under 50 million hours watched).

“All Her Fault” stars Snook alongside a truly excellent cast that includes Jake Lacy, Dakota Fanning, Michael Peña, Jay Ellis, Abby Elliott and Sophia Lillis, and is, according to the review on our other site Static Looper (hmm, there’s something familiar about this author…), a paint-by-numbers psychological thriller that still manages to transcend the genre with sharp writing, an unforgettable touch and incredibly layered performances (especially from Snook and Fanning). If you haven’t yet watched “All Her Fault,” you’re apparently in the minority, but in any case, here’s the gist: Snook plays a mother who is disconcerted when she realizes that not only is her young son not where he’s supposed to be, but he’s actually nowhere to be found at all.

Specifically, when we first meet Sarah Snook’s wealth manager Marissa Irvine in “All Her Fault,” she is picking up her son Milo (Duke McCloud), who is only five years old, from a meeting that is supposed to be with the young son of Marissa’s fellow mother, Jenny Kaminski (Dakota Fanning). When she arrives at the address Jenny provided, Marissa finds an older woman she has never heard of. either mom, and Milo is nowhere to be found; When Marissa gets in touch with Jenny, she then discovers that the latter never provided the address or even texted Marissa about a play date in the first place. The whole thing is a set-up of sorts, and Milo is immediately declared missing – with Detective Jim Alcaras (Michael Peña) leading the investigation. Thanks to Marissa’s immense financial success, she and her family assume that the kidnappers simply want a ransom, but there appears to be something far more sinister at play, particularly around a mysterious woman named Carrie Finch (Sophia Lillis).

I won’t spoil the absolutely twisted ending of “All Her Fault” here, but as you watch, you’ll end up suspecting everyone from Marissa’s troubled sister-in-law, Lia Irvine (Abby Elliott), to Lia’s secret lover and Marissa’s business partner, Colin Dobbs (Jay Ellis), to Marissa’s own husband, Peter Irvine (Jake Lacy). Clearly, all eight episodes of “All Her Fault” resonated pretty well with audiences, and while the entire cast and showrunner Megan Gallagher deserve a lot of credit, a lot of that is probably due to Snook’s mere presence, as the actor has built up an incredible amount of goodwill over the past couple of years.

I’m willing to bet that a lot of people who watched “All Her Fault,” which I did, watched specifically because, like me, they missed seeing Sarah Snook on their small screens. Snook, as you probably know, originated the role of Siobhan “Shiv” Roy in Jesse Armstrong’s masterpiece series “Succession,” which ran from 2018 to 2023 and lasted for four seasons. As the only daughter and youngest child of powerful but elderly media mogul Logan Roy (an imperious Brian Cox), Shiv constantly battles with her buffoonish brothers Kendall and Roman (Jeremy Strong and Kieran Culkin) for potential control of the family business, the conglomerate Waystar Royco. She’s also involved in an engagement and subsequent marriage to bootlicker Tom Wambsgans (Matthew Macfadyen), and to say that Shiv treats this guy poorly is… a massive euphemism.

Which means Snook, who won two Golden Globes and an Emmy for her portrayal of Shiv in “Succession,” has quickly become one of the entertainment industry’s most lauded performers. Not only did she win a Tony Award in 2025 for her absolutely daring and physically daring solo version of “The Picture of Dorian Grey” on Broadway (which also earned her an Olivier Award when the show played in London’s West End), but when the Golden Globe nominations dropped on Dec. 8, she scored another Golden Globe nomination for “All Her Fault.” (It is relatively it’s safe to assume, I think, that another Emmy nod will follow.) Snook is a terrific performer who has established herself as a dramatic powerhouse, and “All Her Fault” continues to prove that she is an exceptional talent.

“All Her Fault” is now streaming on Peacock.
