Written and directed by Mark Neveldine and Brian Taylor (Crank), the film is based on the DC Comics title in which Hex, known for having the right side of his face disfigured and wearing a Confederate army uniform, was a rough-and-tumble gunslinger and part-time bounty hunter whose adventures always ended in blood.
“Jonah Hex,” created by by writer John Albano and artist Tony DeZuniga, first appeared in the early 1970s in the issues of “All-Star Western” before graduating to his own series in 1977 that ran for about 10 years. A new series was launched in 2005. The character also had a run in the 1990s that combined the Western genre with supernatural elements.
