EXCLUSIVE: Comedian Jim Gaffigan has come aboard the dramatic thriller, Them That Follow, joining Thomas Mann, Olivia Colman, Alice Englert, Walton Goggins, Kaitlyn Dever and Cameron Monaghan. Brittany Poulton and Daniel Savage are directing the pic, from their original screenplay about a small community in Appalachia where believers handle poisonous snakes to prove their righteousness before God.

Gaffigan will play Zeke, the pious, steadfast husband of the community matriarch, Hope (Colman). Although he’s one of the pillars of the church, Zeke’s faith is tested when his son, Auggie (Mann), is bitten.

Filming is scheduled to commence this month in Youngstown, Ohio. Alan Siegel and Danielle Robinson of G-Base are producing. Bradley Gallo and Michael Helfant will produce for Amasia Entertainment, which is also financing the project.

Up next, Gaffigan co-stars alongside Jason Clarke and Kate Mara in the soon-to-be-released Ted Kennedy film Chappaquiddick and in the Alec Baldwin-Salma Hayek comedy Drunk Parents.

Gaffigan is a client of Brillstein Entertainment Partners, UTA, and Schreck Rose Dapello & Adams LLP.
