Sarah Snook Reflects on Motherhood and Acting

For Sarah Snook, leaving her then-2-year-old daughter to work on All Her Fault helped her connect to her role as Marissa Irvine, a Chicago businesswoman who faces a terrifying situation. In the series, Marissa goes to pick up her young son Milo from a playdate, only to find she is at the wrong house and that Milo was never there.

“It was useful to kind of use my daughter. What would it be like to have the situation happen to me? I understand that more in depth now being a parent.”

However, Snook admits she could not fully imagine her own child in Milo's place. “If I had, I would have just decided not to work. It’s too hard, it’s too much,” she says.

The Thrilling Premise

Marissa’s search leads her to another mom, played by Dakota Fanning, who denies any knowledge of the missing child, as does the homeowner. The suspense builds as Milo’s disappearance remains a mystery.

“All Her Fault” is a twisty eight-episode thriller with some gasp-worthy moments that takes its depiction of motherhood—and the blame women place on themselves when something goes awry—very seriously.

Summary

This series offers a gripping look at the pressures of motherhood and the complex emotions of guilt and responsibility that many women face.
