It was announced a few weeka ago that production has officially begun in New Orleans on the third season of AMC’s “Preacher“ with several characters from the comic book joining the series, including Tony-winner Betty Buckley (“Supergirl,” Split) as “Gran’ma,” Colin Cunningham (“Blood Drive,” “Falling Skies”) as “TC,” Jeremy Childs (The Last Castle, “Nashville”) as “Jody” and Liz McGeever (“Star,” “Nashville”) as “Christina.”

Now, Deadline reports on a huge addition, Jonny Coyne (The Nun) as Allfather D’Aronique! The cluelessly malevolent character is physically large, overweight, and a revolting slob, but also potentially the most powerful man in the world. He is quietly sinister with eyes that see more than he says.

Here are the previously announced new additions.

Betty Buckley joined 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 loyal caretaker 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.

In Season 2, “After Jesse accidentally discovered that God is absent from Heaven, Jesse, Tulip, and Cassidy set out on a road trip to find Him, all while being hunted by the Saint of Killers, an unstoppable, mythical killer from Hell. The trio’s pursuit led them to New Orleans, where they dodged local gangsters, dangerous agents, and other unimaginable mayhem on their way to uncovering an even bigger secret. Now, with Tulip’s life and Cassidy’s friendship in the balance, Jesse must rely on a mysterious figure from his past in order to save his friends and continue on with his mission.”
