In his first outing behind the camera since Barry, his Emmy-winning dark comedy for HBO, Bill Hader has officially locked in plans to write, direct and star in They Know, a new horror film for MRC, which will begin production in Los Angeles this spring.

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.

With the film, Hader is set to become the latest major comedic talent to make his mark in horror, joining a lineage that includes the likes of Jordan Peele, Zach Cregger, and most recently, Curry Barker.

MRC is the studio financing the project, which is based on an original story Hader created with his Barry collaborator Duffy Boudreau. Bob Graf and Hader are set to produce under the latter’s Hanarply banner, with Alyssa Donovan co-producing.

With his work on Barry, a tragicomedy about a hitman trying to turn over a new leaf as an actor, only for the consequences of his actions to slowly but surely catch up with him, Hader became the rare winner of three DGA Awards, also winning multiple Emmys and Critics Choice Awards. Hader co-created the show with Alec Berg and also served as its co-showrunner, executive producer, director, writer, and star. A longtime cast member on Saturday Night Live, Hader’s other acting credits include Trainwreck, Superbad and The Skeleton Twins. He will next be starring in Warner Bros. Pictures Animations’ The Cat in the Hat, out November 6.

Coming off the release of Emerald Fennell’s Wuthering Heights, which has grossed over $92M worldwide in a little over a week, MRC’s upcoming slate includes The Only Living Pickpocket in New York and The Gallerist, which just premiered at Sundance, as well as A Place in Hell, The Best Is Yet to Come, Unabomer, and Eloise.

Hader is repped by UTA and Felker Toczek Suddleson. Nominated for three Emmys, with additional credits including The Lowdown, Hit-Monkey, Documentary Now!, and Big Mouth, Boudreau is repped by UTA and TroyGould.
