All Her Fault: Sarah Snook on Playing a Successful Mom's Worst Nightmare

Plot Overview

Snook plays Marissa, a self-made wealth manager whose young son, Milo, disappears during a playdate with a classmate.

Sarah Snook’s Perspective

Also serving as an executive producer, Snook reflected on the emotional demands of the role during a recent press conference. She emphasized the importance of portraying the trauma authentically, avoiding exaggerated reactions.

“It is high drama, but like getting into this hysterical, histrionic overreacting … like finding the kernel of truth in these things. Like, ‘What is it like to have your child go missing? What is that like?’ 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.”

She also revealed how emotionally taxing the role was, saying:

“We’re during the first read through and I write on the first page: ‘Must find different ways to cry.’ Because I was crying all the time, dealing with what’s happening. Finding different levels of like, ‘Okay, this is level 10.’”

Summary

Sarah Snook delivers a deeply emotional and nuanced performance in All Her Fault, exploring a mother’s harrowing experience with heartbreaking authenticity.
