The 'Watchmen' alum has booked a six-episode arc in the adaptation of the controversial graphic novel.

AMC's Preacher adaptation has enlisted Oscar nominee Jackie Earle Haley to play an iconic character from the graphic novel.

Haley has been tapped for a six-episode arc on the upcoming AMC drama, where he will portray the iconic character of Odin Quincannon, The Hollywood Reporter has learned.

Based on Garth Ennis and Steve Dillon's 1990s comic series from DC Comics imprint Vertigo, Preacher revolves around Rev. Jesse Custer (Agent Carter's Dominic Cooper), a badass Texas preacher who, after losing his faith, learns that God has left heaven and forsaken his duties. Jesse becomes the only one who is able to track God down and hold him responsible for his abdication. Tulip O'Hare (breakout Ruth Negga), Jesse's beer-guzzling vampire ex-girlfriend, accompanies him on his quest for answers.

Haley's Odin is described as a small, decrepit man with the unscrupulous iron will necessary to be the most powerful man in Annville County, Texas. The chief employer in town, Odin runs Quincannon Meat & Power, a 125-year-old family-operated slaughterhouse business.

In the comics, Odin is a member of the local KKK branch and clashes multiple times with Jesse, with the latter eventually discovering him having sex with a mannequin made out of meat products.

Repped by Gersh and Leslie Allan-Rice Management, Preacher marks Haley's latest role in a comic-book adaptation. He previously portrayed Rorschach in the feature-film take of Watchmen (2009). His credits also include Little Children and The Bad News Bears.

Preacher, expected to debut in the summer, hails from executive producers Sam Catlin (Breaking Bad), Seth Rogen and Evan Goldberg (This Is the End).
