"I hear tell of a "Princess of Mars" series."
Sounds interesting, do you have any refs for it?

Article is from Oct. 6, 2005. The project is on hold while the director, Jon Favreau, completes Iron Man. Don't really know much more about it.
Thanks for that link! I had never read this series. Went to the site and started reading it last night!
