All Her Fault

All Her Fault is a high-stakes psychological suspense thriller television series starring Sarah Snook. The drama series features Snook in the lead role of Marissa Irvine, trading corporate backstabbing from her previous roles for pure psychological terror in an intense project designed to keep audiences on the edge of their seats from the start.

The narrative begins with immediate psychological horror rather than traditional action elements such as sudden gunfire, high-speed car chases, or heavy pyrotechnics. Snook revealed that the series opens with a bang that alters everything for her character by dropping viewers straight into a parent's absolute nightmare right out of the gate.

The project earned industry attention as a nominee for Outstanding Limited or Anthology Series at the 2026 Primetime Emmy Awards. It competed in a crowded limited series category against other high-profile shows including DTF St. Louis, Beef, and Love Story: John F. Kennedy Jr. & Carolyn Bessette.
