The film stars Josh Brolin, John Malkovich, Michael Shannon, Will Arnett, Megan Fox and Daniels from The Wire (a.k.a. Lance Reddick). From the official site:
Jonah Hex (Josh Brolin) is a scarred drifter and bountyhunter of last resort, a tough and stoic gunslinger who can track down anyone…and anything. Having surived death, Jonah’s violent history is steeped in myth and legend, and has left him with one foot in the natural world and one on the “other side.” His only human connection is with Lilah (Megan Fox), whose life in a brothel has left her with scars of her own. But Jonah’s past is about to catch up with him when the U.S. military makes him an offer he can’t refuse: in exchange for his freedom from the warrants on his head, he must track down and stop the dangerous terrorist Quentin Turnbull (John Malkovich). But Turnbull, who is gathering an army and preparing to unleash Hell, is also Jonah’s oldest enemy and will stop at nothing until Jonah is dead.
