The third season of Preacher is ready to explore the darkest corners of the comic. Season two ended with Jesse, Tulip and Cassidy driving up the road to the L'angelle farm, home of Jesse's psychotic, abusive family. It seemed certain that the next season would have to feature Jesse's terrifying grandma and her minions, and a new press release confirms that they are indeed joining as recurring cast members.

AMC is adding Marie L'angell to the cast, here simply named Gran'ma, as played by Betty Buckley (Split). Jeremy Childs (Nashville) will play Jody, the man who taught Jesse everything he knows about violence. Colin Cunningham (Falling Skies) will play TC, Jody's gleefully perverse sidekick. Finally Liz McGeever (Homeland) will be playing Christina, who shares a name with Jesse's mother in the comics, though her official description doesn't mention that exactly.

The official character descriptions, as described by AMC are as follows:

Betty Buckley joins the cast as “Gran’ma” – A spiritist with true powers, who can cast spells and even bring back the dead (for a price). Pay the fee or pay with your soul to feed Gran'ma's thirst for eternal youth. She is weathered, tough, and mean, but also intelligent beyond measure. She’s Jesse's only living family and she loves him.

Colin Cunningham joins the cast as “TC” – A man born of the bayou and the loyalcaretaker and soldier for Gran'ma. Weasely and wiry, he'll gladly tell you about his perversions whether you ask him or not. While he seems like the friendliest guy you'll ever meet, don’t make the mistake of turning your back on him.

Jeremy Childs joins the cast as “Jody” -- Massive and intimidating, Jody emanates danger. He’s the enforcer for Gran’ma and the only man Jesse’s never beaten in a fight. He’s nobody’s fool, and not someone to cross.

Liz McGeever joins the cast as “Christina” - Capable and efficient, Christina has a face that lures customers in for her family business. Christina hides it well, but she hates her job and has dreams and aspirations outside of her current life -- but suffers to protect her child.

Preacher stars Dominic Cooper as Preacher Jesse Custer, Ruth Negga as Tulip and Joe Gilgun as Cassidy the Vampire.
