Fox says she wants the comic book 'fanboys' to like the film, but adds that, to be successful, it has to reach beyond that small but loyal fan base. "I feel like it's impossible to please the hardcore comic book fans because they'll never be happy no matter what you do. You can't focus completely on pleasing them because you'll never win and then you're excluding a whole other world of people who weren't aware of the comic in the first place. So I think you have to take some liberties to make it into a live-action film or it wouldn't work," she says.

"Jonah Hex" co-stars John Malkovich as the villain, Turnbull. The cast also features Michael Shannon, Michael Fassbender and Will Arnett. After achieving success as an animator, Canadian-born Jimmy Hayward makes his live-action directing debut with "Jonah Hex."
