🚨 JUST DROPPED: Peacock’s hottest mystery thriller explodes onto screens TODAY—starring an Emmy-slaying powerhouse in a web of lies, secrets, and suburban nightmares that’ll have you glued. 😱 Early buzz? A killer 83% on Rotten Tomatoes already. But is it the next binge obsession? Who’s hitting play first?

Sarah Snook is trading the cutthroat boardrooms of Succession for the treacherous cul-de-sacs of suburban London in Peacock’s latest limited series, All Her Fault. The Emmy-winning Australian actress headlines the six-episode mystery thriller, which drops its first four installments today, November 6, 2025, earning quick praise from critics with an 83% Tomatometer score on Rotten Tomatoes based on initial reviews. It’s a solid debut for a show that’s already drawing comparisons to hits like Big Little Lies and The Undoing, blending domestic drama with pulse-pounding suspense.

Based on the 2021 novel by Andrea Mara, All Her Fault follows Marissa Irvine (Snook), a high-powered lawyer whose seemingly perfect life unravels when her young son vanishes from their front yard during a neighborhood playdate. What begins as a frantic search spirals into a labyrinth of hidden grudges, buried secrets, and finger-pointing among the tight-knit—and increasingly hostile—community of Willowbank Gardens. As police zero in on Marissa herself, she races against time and suspicion to uncover the truth, questioning everyone from nosy neighbors to her own inner circle.

Snook, 38, steps into the role with the kind of raw intensity that made her Shiv Roy a Succession standout, earning her a 2023 Primetime Emmy for Outstanding Lead Actress in a Drama Series, plus two Golden Globes and a Critics Choice Award. Her portrayal of the Roy family’s cunning youngest daughter catapulted her from indie darling—roles in Predestination and The Dressmaker—to global icon, with Succession‘s finale in 2023 cementing her as TV’s sharpest anti-heroine. “Sarah brings this incredible vulnerability layered over steel,” director Jessica Hobbs (The Handmaid’s Tale) told Variety in a recent profile. “Marissa’s not just fighting the world—she’s dismantling it from the inside.”

The ensemble bolsters Snook’s tour de force with familiar faces primed for breakout turns. Dakota Fanning, 31, plays Marissa’s brittle best friend Ellie, a yoga-influencer mom harboring her own demons—Fanning’s first major TV gig since The Alienist trilogy wrapped in 2020. Jake Lacy (White Lotus Season 1’s sleazy Shane) embodies Marissa’s devoted but flawed husband, Roisin, whose corporate secrets threaten to torpedo the investigation. Sophia Lillis, 23, the It scream queen turned indie darling in I Am Not Okay with This, steps up as the enigmatic teen next door with ties to the disappearance. Abby Elliott (The Bear‘s ever-reliable Sugar) and Michael Peña (Ant-Man‘s gruff Luis) round out the suspects as a pair of meddlesome neighbors whose facades crack under scrutiny.

Created by Malaika Mfalme (Snowfall) and executive produced by Snook herself alongside Hobbs and Mara’s team, All Her Fault adapts the bestseller with a keen eye for psychological tension. Filming wrapped in London’s outskirts last spring, capturing the eerie contrast between manicured lawns and simmering resentments. “The book hooked me because it’s not just about the ‘what happened’—it’s the ‘why do we do this to each other?’” Mfalme said at a virtual press junket. “In a world of Ring doorbells and Facebook mom groups, paranoia is the new normal.”

Early reviews are pouring in ahead of the drop, praising the series for its taut pacing and Snook’s magnetic pull. The Hollywood Reporter‘s Angie Han called it “a deliciously addictive guilty pleasure, with Snook anchoring every twist like a pro.” IndieWire gave it a B+, noting, “It leans into the soapier side of thrillers, but damn if it doesn’t work—especially when Fanning and Lacy go full feral.” The 83% score, derived from six critics so far, marks All Her Fault as Certified Fresh, though some quibble it’s no Succession (96% average). Variety‘s Caroline Framke warned, “Expect comparisons, but don’t sleep on this—it’s got claws.”

Peacock, NBCUniversal’s streaming arm, is betting big on the title as part of its post-strike content surge. The platform, which launched in 2020, has carved a niche with prestige imports like The Office reruns and originals such as Poker Face (Season 2 hit 100% in May 2025) and Based on a True Story. All Her Fault slots into Peacock’s growing thriller lane, following Fight Night: The Million Dollar Heist (2024’s 85% scorer) and the upcoming The Day of the Jackal remake. With ad-supported tiers starting at $5.99/month and premium at $11.99, the service reported 34 million subscribers last quarter—a 15% bump year-over-year, per Comcast earnings.

Snook’s post-Succession trajectory has been a masterclass in selective reinvention. After turning down several HBO pilots to avoid Logan Roy’s shadow, she dipped into features with a voice role in The Garfield Movie (summer 2024’s surprise hit) and a lead in A24’s Materialists, a rom-com opposite Pedro Pascal set for 2026. TV-wise, whispers of a Succession spin-off focusing on Shiv persist, but Snook’s team shut them down at TCA in July: “She’s done with the Roys—for now.” All Her Fault marks her first scripted series lead since the HBO juggernaut, and insiders say it’s a deliberate pivot to “grounded genre” that lets her flex dramatic range without the prestige baggage.

The cast’s chemistry was a highlight on set, per a Deadline deep dive. Fanning, reuniting with Snook after The Girl from Plainville (2022), bonded over shared Aussie expat woes. “Dakota’s got this quiet ferocity—it’s terrifying in the best way,” Snook shared in a Marie Claire cover story. Lacy, fresh off Girls5eva Season 3, joked about his character’s arc: “I’m the husband everyone loves to hate, but wait till the third episode.” Lillis, now 23 and eyeing directing, brought youthful edge, drawing from her Sharp Objects scars. Peña and Elliott, both SNL alums in spirit, injected levity into the gloom—Elliott’s comic timing a nod to her Oath roots.

Mara’s novel, a Sunday Times bestseller, tapped into pandemic-era anxieties about child safety and social media vigilantism. Published amid lockdowns, it sold 500,000 copies in the UK alone, spawning a German adaptation in 2023. Mfalme’s script amps up the racial and class undercurrents—Marissa’s Irish immigrant background clashes with the WASPy enclave—without preaching. “It’s not message fiction; it’s mirror fiction,” Hobbs explained. “You see your own neighborhood in it.”

Promotion has been a slow burn, with Peacock teasing snippets at New York Comic Con in October. A trailer dropped last week, racking up 12 million views on YouTube, featuring Snook’s tear-streaked interrogation and a chilling score by Hildur Guðnadóttir (Joker). Social buzz is building: #AllHerFault trended on X yesterday, with fans posting “Snook as a suspect mom? I’m unhinged already.” Early audience scores on Rotten Tomatoes hover at 78% from 200+ users, praising the “non-stop hooks” but docking points for “predictable turns.”

Yet not everyone’s sold. A Guardian review dinged the finale for “rushing the reveals,” scoring it 2/5 stars, while The AV Club quipped it’s “prime water-cooler fodder, if your cooler runs on Chardonnay.” The score could climb as more reviews roll in—All Her Fault is positioned as Peacock’s answer to Netflix’s true-crime boom, sans the docs.

For Snook, it’s personal. In a Vogue Australia interview, she reflected on motherhood—her 2024 debut with husband Billy Connolly Jr.—mirroring Marissa’s terror. “Becoming a parent sharpened my edges for this,” she said. “It’s not abstract anymore.” The role also reunites her with Hobbs, who directed her Succession swan song.

As the remaining episodes hit weekly, All Her Fault arrives at a thriller-saturated moment. Netflix’s The Residence (75% in October) and Hulu’s Paradise (86%, starring Sterling K. Brown) set a high bar, but Snook’s draw could tip the scales. Peacock’s strategy—bundling with Bravo and sports—aims to retain eyeballs amid cord-cutting.
