Sarah Snook Peacock Series ‘All Her Fault’ Rounds Out Main Cast

The Sarah Snook-led Peacock series “All Her Fault” has filled out its main cast with three new additions, Variety has learned exclusively.

Daniel Monks (“Ricky Stanicky,” “Kaos”), Duke McCloud (upcoming “Kinda Pregnant”), and Kartiah Vergara (“Ticket To Paradise,” “Dora the Explorer: The Lost City of Gold”) have all signed onto the series, which is based on the Andrea Mara novel of the same name.

The show was originally picked up to series at Peacock back in June with Snook in the lead role. The cast also includes Dakota Fanning, Abby Elliot, Jake Lacy, Sophia Lillis, Jay Ellis, Thomas Cocquerel, and Michael Peña. Monks will play the character Brian, while McCloud will play Milo and Vergara will play Ana.

The official logline for the series states, “Marissa Irvine (Snook) arrives at 14 Arthur Avenue, expecting to pick up her young son Milo (McCloud) from his first playdate with a boy at his new school. But 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.”

Nigel Marchant, Gareth Neame and Joanna Strovens of Carnival Films also executive produce along with Jennifer Gabler Rawlings and Christine Sacani. Minkie Spiro will direct the multiple episodes, including the first, and serve as an executive producer. Terry Gould is a producer while Mara is an associate producer.
