Emmy winner Sarah Snook (Succession<\/em><\/a>) stars in Peacock\u2019s gripping thriller All Her Fault<\/em><\/strong>, based on Andrea Mara\u2019s bestseller. The eight-episode series premiered on November 6, 2025, and follows Sarah Snook as Marissa, a successful, self-made wealth manager whose young son, Milo, disappears while on a playdate with a classmate. Or at least that\u2019s where Marissa and her husband, Peter (Jake Lacy, Apples Never Fall<\/em><\/a>), believed their son to be until Marissa tries to pick him up and discovers he\u2019s vanished.<\/p>\n Snook, who also serves as an executive producer, recently participated in a press conference in support of the Peacock series. Discussing the challenges of taking on the role, Sarah Snook said she needed to find a way to portray the reality of the traumatic situation.<\/p>\n \u201cIt is high drama, but like getting into this hysterical, histrionic overreacting \u2026 like finding the kernel of truth in these things. Like, \u2018What is it like to have your child go missing? What is that like?\u2019 For this person like that, that was the hardest thing to constantly make sure that we were delving down into what is the truthful version of this.\u201d<\/p>\n Snook added, \u201cWe\u2019re during the first read through and I write on the first page: \u2018Must find different ways to cry.\u2019 Because I was crying all the time, dealing with what\u2019s happening. Finding different levels of like, \u2018Okay, this is level 10. This is a guilt cry. This is a shame cry. This is a fear cry. This is a sorrow cry.\u2019 You know, finding ways to create light and shade with a palette like that is tricky.\u201d<\/p>\n
