True Blood alumna Lucy Griffiths has joined the cast of AMC drama pilot Preacher, based on Garth Ennis and Steve Dillon’s cult 1990s comic. Dominic Cooper continues to be in negotiations for the lead in the project, from Seth Rogen & Evan Goldberg, Sony TV and AMC Studios. It centers on 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 (Joseph Gilgun), the three embark on a journey to literally find God.

British actress Griffiths, repped by Don Buchwald & Associates, Principal Entertainment LA and UK’s Hamilton Hodell, plays Emily, a no-nonsense single mother of three who is a waitress, the church organist, bookkeeper and Jesse’s loyal right hand. The cast also includes Ian Colletti, who was plays Eugene Root, aka Arseface.
