The classic Jonah Hex stories by Micheal Fleisher are great and I recommend them. Michael Fleisher wrote one hundred and twenty five Jonah Hex stories. The movie was inspired by the classic Jonah Hex stories written by Micheal Fleisher, specifically the Quentin Turnbull issues. The movie features Quentin Turnbull as the villain, who first appeared in Weird Western Tales #22 (1974), written by Micheal Fleisher, and when the movies script was written in 2007, Quentin Turnbull hadn't appeared in a comic book since Jonah Hex #85 (1984), written by Micheal Fleisher.
John Malkovich explained "I play a plantation-owner called Quentin Turnbull, who holds Jonah Hex responsible for the death of his son in the Civil War it's set right after the American Civil War, 1872, I think it's set in. It's Josh, Megan and Michael Fassbender, who's terrific. I love Josh Brolin he's a friend of mine, and he said, 'Would you be interested?' And I like the guy, Jimmy Hayward, who's directing, so I said, 'Sure.'"

Quentin Turnbull being a plantation-owner holding Jonah Hex responsible for the death of his son in the Civil War is right out of those classic Jonah Hex comic books written by Micheal Fleisher. Michael Fleisher created Quentin Turnbull. Quentin Turnbull was a driving force in Jonah's life in those comic books. We see, in flashbacks, the death of Quentin Turnbull's son in Weird Western Tales #29 (1975), one of the best and most pivotal Jonah Hex stories. We also see in that issue that Jonah Hex and Quentin Turbull's son Jeb had given Quentin Turnbull the Eagle-topped cane in 1861.
Southerner Jonah joined the Civil War as a Confederate in 1863 but after killing a slave Jonah is remorseful and decides that he can't continue to kill slaves and Yankees that are fighting for men to be free, but he can't turn and fight against his Confederate comrades, either. Jonah surrenders to the Union solders at Fort Charlotte. Jonah's Confederate platoon is subsequently captured. The Confederate solders turn against Jonah thinking of him as traitor and call him a "sneaky, ******-lovin'...", and then many of them are killed during an attempted escape known as the Fort Charlotte Massacre. Jeb is shot and dies in Jonah's arms. Jonah later hunts down the captain and kills him in revenge. Jonah is accused by the surviving Confederate solders of being a traitor. Two weeks later when the news of Jeb's death and Jonah's betrayal reaches Quentin Turnbull, he swears vengeance upon Jonah for the death of his son. That's all in the flashback in Weird Western Tales #29 (1975). So Turnbull hires assassinations to kill Jonah Hex and the first confrontation is in 1872 in Weird Western Tales #22 (1974).

Jimmy Palmiotti, writer of the current Jonah Hex comic book series, told the Philadelphia Daily News about the additional filming that "I know for a fact that the shoots on Hex are additional story being added...not reshoots." And the reason they pushed up the release date of the film to June 18th is "because the studio saw the rough cut and loved it, so much so they pushed up the date and decided to put more money into the film."

In February Jimmy Palmiotti further explained that "they are doing some additional scenes which will help expand on the story and back story, a good thing, trust me."

The movie does sound pretty brutally violent. In the teaser that was shown at Comic-Con there's a scene of a guy asking what happened to Jonah Hex's face. Jonah says, "I cut myself shaving," shoves an axe in his head and says, "What happened to yours?"
