EXCLUSIVE: AMC’s Preacher has cast another co-lead. British actor Joseph Gilgun (This Is England) has joined the drama pilot based on Garth Ennis and Steve Dillon’s cult 1990s comic. The project, from Seth Rogen & Evan Goldberg, Sony TV and AMC Studios, is about Jesse Custer, a conflicted Preacher in a small Texas town who merges with a creature that has escaped from heaven and develops the ability to make anyone do anything he says. Along with his ex-girlfriend, Tulip (Ruth Negga) and an Irish vampire named Cassidy (Gilgun), the three embark on a journey to literally find God.

Jesse’s sidekick Cassidy is described as the most wild-ass, bestest “bro” you’d ever want to meet. He may be 100 years dead but no one’s more boisterously alive than Proinsias Cassidy. An incorrigible mischief-maker, Cassidy’s up for anything — joyriding, bungee-jumping, bank robbing, peyote dropping. He’s also a relentless conversationalist with opinions on everything from religion to politics to pop culture to theories on why people are better able to tolerate the odor of their own flatulence.

In addition to Negga, Gilgun joins Ian Colletti who was cast as Eugene Root, aka Arseface. Dominic Cooper has been in conversations for the lead, Jesse.

While he has been steadily working in film in TV in his native England for a decade, Preacher marks only Gilgun’s second U.S. gig — he is co-starring opposite Vin Diesel in the upcoming feature The Last Witch Hunter. Gilgun is repped by UK’s Hamilton Hodell and Peikoff Mahan.
