A parent's worst nightmare - of their child, a 5-year-old, being taken - as viewers discovered, is only one of the Peacock psychological thriller's many twisty layers. And its those layers that convinced executive producer and Carnival Films managing partner Nigel Marchant, whose credits include Downton Abbey and The Day of the Jackal, to scoop up Irish author Andrea Mara's homonymous bestseller for Megan Gallagher to adapt on the small screen.

Gallagher, says Marchant, "really helped cement some of those twists and turns" as well as capture the underlining themes "about the inequality of domestic labor in straight married couples where mothers have to be the CEO both at home and in the office, [as well as] how women in these circumstances face a harsher sense of scrutiny than men." There was never a question that Snook, who has an Emmy for her role as Shiv Roy in HBO hit Succession and a Tony for her Broadway debut in The Picture of Dorian Gray (where she played 26 characters), could inhabit lead character Marissa's many emotions to anchor the series, which also stars Michael Peña, Jay Ellis, Abby Elliott and Emmy nominees Jake Lacy and Dakota Fanning. Snook's presence, Fanning shared, drew her to the role of Jenny Kaminski, mother to Jacob (Tayden Jax Ryan), Marissa's son Milo's (Duke McCloud) intended playmate. "I was excited at the opportunity to work with Sarah as such a fan of hers," she shared. "I knew most of my scenes would be with her and that our relationship would be at the center of a lot of the story." Who and what Jenny represents also enticed Fanning: "There were things in Jenny that everyone could kind of see themselves in. Even if they don't have kids yet or aren't married, they can see the struggles she's going through of just trying to be everything to everyone." Considering Jenny's nanny Carrie (a breakout role for Sophia Lillis) is, as viewers ultimately discover, the one who took Milo, the two mothers evolving into supportive friends is not the typical direction for these characters. "You might expect it to go down in flames and become the pointing fingers thing," noted Fanning. "We flipped that on its head and said, 'No, these two are going to be friends, and they're going to help each other through this. They're going to lean on one another and learn things from one another.'" In the spirit of learning some of the whys behind the key moments of All Her Fault, The Hollywood Reporter questioned Snook and Gallagher - who, outside of their main roles as actor and showrunner, also serve as executive producers of the series - and asked if this is really the end and a limited series adaptation, or if a second season could be in the cards. *** Let's talk about the ending and Milo actually being Carrie's (Sophia Lillis) son, whose real name is Josephine. SARAH SNOOK One of the hardest things with a story with as many twists and turns and size of the plot [here] is that you have to be a dean of the details. You have to make sure who knows what piece of information when. Does the audience really understand this is Josephine instead of Carrie? All the pieces that fit together, and the timing of that information coming out, has to work together and work well. Megan, as you know, was hugely instrumental - obviously, because she's a writer - in creating and passing it out. For me as an actor, it's a joy to work on scenes where you have multiple characters all with slightly different information, who are all finding out new information together. Those revelation scenes are amazing to act out. Was that element something that really captivated you about Andrea Mara's novel when you were adapting it, Megan? MEGAN GALLAGHER Absolutely. So often thrillers live and die by their endings. So many of them hook you in and are interesting, and then start treading water and peter out. But Andrea's novel is such a whopper of an ending. She really swung for the fences and did an incredible job. So it was so fun and reassuring, because, as Sarah points out, it's a complex show with lots of twists and turns. It's so helpful to have such a big North star that you're
