Arnold Schwarzenegger is returning as Conan the Barbarian. Announced earlier this year, King Conan will bring him back to reprise his role. Speaking to the long-running Schwarzenegger fan site The ArnoldFans, “Next year, we are going to do King Conan.” It was more than a decade-long journey to find “someone who really understands [Conan author] Robert E. Howard that understands the artwork of Frank Frazetta and to continue on.” Schwarzenegger also wants to bring back Barbarian director John Milius as a producer.  

If you look at IMDB there are currently five writers associated with the production, how many will get official credit remains to be seen.  Current credits include:  Will Beal, Andrea Berloff, Robert E. Howard (based on his characters but also listed as a screenwriter), Christopher McQuarrie, and Chris Morgan.

I have little doubt this will be a good if not great movie, McQuarrie as writer/director will not allow it to be less in my opion.
