Casting continues on the Preacher pilot at AMC, from writers/directors Seth Rogen and Evan Goldberg. The potential series is an adaptation of the beloved Garth Ennis graphic novel of the same name, and fans are no doubt hoping that Rogen and Goldberg are the ones who can finally bring this property to the screen.

Per Deadline, Dominic Cooper—who played Howard Stark in Captain America: The First Avenger as well as Marvel’s Agent Carter TV series—continues to be in negotiations for the lead role of 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 what he says. This would be a major starring role for the very talented Cooper, who was first rumored for the part last month.

In terms of solidified casting for Preacher, Deadline says True Blood actress Lucy Griffiths has signed on in an unspecified role. Griffiths was poised to be the female lead on NBC’s Constantine before the network opted to change course and kill her character off in the pilot. No matter, that freshman series’ future looks murky at best.

So far, Rogen and Goldberg have already assembled a fair amount of their ensemble. Ruth Negga (Agents of S.H.I.E.L.D.) will play Tulip, Ian Colletti (Rake) is Arseface, and Joseph Gilgun (This Is England) recently signed on to play Irish vampire Cassidy.

Rogen and Goldberg co-wrote the pilot with Breaking Bad alum Sam Catlin, who will act as showrunner should AMC order the pilot to series. Production will get underway this summer in anticipation of a potential 2016 debut.
