Actor Sarah Snook, who is widely recognised for her role in HBO's black comedy-drama series Succession, is all set to star in and executive produce the upcoming thriller series All Her Fault at Peacock. The series is based on a best-selling novel of the same name by Andrea Mara.

All Her Fault revolves around Marissa Irvine, played by Snook, who experiences every parent's worst nightmare when she goes to pick up her son Milo from his first playdate. However, the woman who answers the door is unfamiliar and doesn't have Milo. Details regarding rest of the cast members and a release date have not been revealed yet.

Snook's role as Shiv Roy in Succession earned her an Emmy award in 2023. She also won two Golden Globes for the same. She is also known for her role in the drama series Soulmates, Netflix's Black Mirror and films like Steve Jobs, Pieces of a Woman, Predestination, and The Glass Castle.

Megan Gallagher serves as the creator of the series while also executive producing it with Snook. Minkie Spiro will direct multiple episodes, including the premiere, and join as an executive producer. Other executive producers include Nigel Marchant, Gareth Neame, Joanna Strevens, Jennifer Gabler Rawlings, and Christine A. Sacani.
