Bill Hader, the Emmy-winning creator of the dark comedy 'Barry', is set to make his directorial debut with the MRC horror film 'They Know'. The film will see Hader writing, directing, and starring in a story centered around a divorced dad's growing suspicion that his ex-wife is secretly dating a mysterious man who influences their children. This marks a significant shift for Hader, who is known for his comedic talents, as he ventures into the horror genre, joining a lineage of comedic talents who have made their mark in horror, such as Jordan Peele and Zach Cregger. The film is based on an original story created by Hader and his 'Barry' collaborator, Duffy Boudreau, and will begin production in Los Angeles this spring. With his production company, Hanarply, and co-producer Alyssa Donovan, Hader is poised to make a significant impact in the horror genre. MRC, the studio financing the project, is also known for its recent success with 'Wuthering Heights', which has grossed over $92M worldwide. Hader is represented by UTA and Felker Toczek Suddleson, while Boudreau is represented by UTA and TroyGould. Nexus Point News was the first to report on 'They Know'.
