Bill Hader is set to write, direct and star in upcoming horror movie They Know, which marks Hader's return to the horror genre seven years after the release of It: Chapter Two. It's also his directorial debut in a feature film after directing some Barry episodes in the past.
Per Deadline, They Know centers on a divorced dad (Hader) who grows suspicious that his ex-wife is secretly dating a mysterious man who is having a strange influence on their children. The story is based on an original story Hader created with his Barry collaborator Duffy Boudreau, which he teased back in 2023.
