Bill Hader is actively preparing his feature directorial debut, They Know, for potential distribution after successfully wrapping production in May 2026. The psychological horror project, which Hader directs and stars in alongside Linda Cardellini, has officially entered the sound mixing phase and is expected to be screened for prospective distributors soon, according to an IndieWire interview published by ComicBook.com on October 20, 2026.
Plot and Creative Origins of They Know
The film follows a divorced father, played by Hader, who suspects that his former wife is secretly dating a mysterious man. As the relationship progresses, the stranger’s influence on their children becomes increasingly troubling. The project draws directly from real-life discussions that Hader and his frequent collaborator Duffy Boudreau had regarding divorce, co-parenting dynamics, and the difficult situations that can surface even when former partners maintain amicable relationships.
Hader previously collaborated with Boudreau on the critically acclaimed HBO dark comedy series Barry, which earned Hader multiple DGA Awards, Emmys, and Critics Choice Awards. MRC is financing They Know, with Bob Graf and Hader producing under Hader’s Hanarply banner, and Alyssa Donovan serving as co-producer.
Production Insights and Directorial Choices
During a rehearsal for the psychological horror film, an unexpected performance choice by co-star Linda Cardellini completely altered the planned approach to a key scene. What had originally been storyboarded to require four or five separate camera shots was adapted on the spot into a sequence intended to play out in a single, continuous take.
This creative pivot highlights Hader’s hands-on approach to his feature debut behind the camera. Having previously directed numerous episodes of Barry, Hader transitions into feature-length filmmaking with a project that blends intimate family dynamics with unsettling genre elements.
Anticipated Distribution and Release Timeline
With principal photography completed in May 2026 and sound mixing currently underway, They Know is gearing up for industry screenings to secure a formal distribution home. Industry observers are closely watching the project as one of the most anticipated horror debuts of the coming slate.
