"Preacher" fans can expect some surprises in AMC's upcoming adaptation of the beloved Vertigo series originally penned by Garth Ennis and Steve Dillon, according to the new show's producers.

Speaking to the Television Critics Association on Friday, Evan Goldberg Seth Rogen and Sam Catlin, the self-avowed loyalists of the beloved comic series who developed the property for the small screen, discussed their new show and the alterations they made to the story of Rev. Jesse Custer's quest against God, which they say will better suit the format, come with the blessing of the original author, and will keep familiar fans on their toes.

"We talked to Garth [Ennis] and he encouraged us to make small changes," Goldberg said, according to the Hollywood Reporter.

Likening the process to that of fellow AMC comic series adaptation "The Walking Dead," the producers promised to be true to the original while affording themselves certain flexibilities. Revisions include the origins of Arseface, played by Ian Colletti, which they say was updated to make the character more sympathetic.

The show's creators say they embrace the creative challenges and opportunities presented in adapting the story to a new medium, which they hope will win over fans, whether they are familiar with the series or not.

"We're fans of the comic. We love the comic. And we're going to make a show that we like, so we hope that translates to people that love the comics, as well," Seth Rogen told press, according to Variety, adding, "Our goal is to make a great, entertaining, fun TV show that, if you've never heard of the comic book, you'll love."

Die-hard fans of the story can expect additional layers to enjoy beyond what a casual one might notice, according to Catlin, who said, "People who know the comics, there are all sorts of Easter eggs throughout it."

"We want fans who love the comic to get everything they want--but we make twists and turns," Goldberg explained.

Starring Dominic Cooper, Ruth Negga and Joseph Gilgun as Rev. Jesse Custer, Tulip O'Hare and Cassidy, the "Preacher" pilot will debut at March's South by Southwest festival before making its eventual network premiere at an as-yet unannounced date. Check out a trailer of the AMC series below.
