All Her Fault cast: Sarah Snook and Dakota Fanning star
The cast of the new and twisted drama is star-studded, but who makes up the ensemble?

It's the kind of drama that has a central premise that will be nightmare-inducing for many viewers, but especially parents. All Her Fault centres on the mystery disappearance of a young boy who is believed to be at a playdate.
But when his mother Marissa Irvine (Sarah Snook) goes to collect him, she finds a woman that has never heard of or seen Marissa or her son Milo. While the search starts notching up, secrets are soon uncovered and the seemingly perfect Irvine family starts to show some cracks, proving that they may be everything but.
Succession star Snook leads the cast as grief-stricken mother Marissa while her newfound mum friend Jenny is played by Dakota Fanning. Snook is joined by Jake Lacy (Apples Never Fall) as Marissa's husband Peter, with the rest of the cast boasting familiar faces from shows like The Bear, Insecure and Kaos.
