“Hex” 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.
Unfortunately, this won’t be a direct adaptation of the western. Instead, the filmmakers plan on adding a lot of “supernatural overtones to develop a franchise”. This could be a really big mistake – it sounds like they are going to have Jonah fighting vampires and werewolves ala the DarkWatch video game. While the game was fun, I just don’t see Jonah Hex as Jericho Cross.
