Jonah Hex has hit a roadblock: Crank and Pathology writer/directors Mark Neveldine and Brian Taylor have left the film adaptation of the comic series. The duo wrote the script, but their exit as directors was attributed to “creative differences.” No other details was provided.

Being developed by production companies Mad Chance and Weed Road, the studio is moving quickly to get a new director. The film is still being targeted for a Spring 2009 start.
