DJ Caruso directing Preacher. But who will play Arseface?

Preacher, Garth Ennis' ultra violent comic about a Texas preacher who travels the US searching for God and only finds horror, junkie vampires, and insanity, is getting made into a movie by Disturbia's DJ Caruso. How is this possible?

Earlier today DJ Caruso twittered that he was officially making Preacher:

My deal just closed on Preacher. Going back to the dark side and pretty fucking pumped!

Great for him. But seriously, how in the hell is this movie going to get made? For those of you that have read the comic, you know what we're talking about. Women are abused and turned into junkies, people blow their faces off with shot guns, and the comic is an orgy of gore and violence. Heck, the main character, Jesse Custer, murders his entire congregation (granted, he's possessed by Genesis, but still). We have absolutely no idea how Caruso can make this film without watering it down into an unrecognizable mess. But what we do know is that it MUST have the character Arseface (Preacher's break-out comic book character).

Here's a synopsis:

Preacher tells the story of Jesse Custer, a down-and-out preacher in the small Texas town of Annville. Custer was accidentally possessed by the supernatural creature named Genesis in an incident which killed his entire congregation and flattened his church.

Genesis, the product of the unauthorized, unnatural coupling of an angel and a demon, is an infant with no sense of individual will. However, as it is composed of both pure goodness and pure evil, it might have enough power to rival that of God Himself. In other words, Jesse Custer, bonded to Genesis, may have become the most powerful being in the whole of living existence.

Custer, driven by a strong sense of right and wrong, goes on a journey across the United States attempting to (literally) find God, who abandoned Heaven the moment Genesis was born. He also begins to discover the truth about his new powers. They allow him, when he wills it, to command the obedience of those who hear and comprehend his words. He is joined by his old girlfriend Tulip O'Hare, as well as a hard-drinking Irish vampire named Cassidy.

The film has been at Columbia for some time and was originally pegged to Sam Mendes. While we're excited to see what will happen with a Preacher movie, we have no idea how they're going to translate this cruel world onto the big screen.
