Stumbled across this today, posted by the staff of Gygax Magazine. Apparently this movie almost happened much earlier, and Gygax had hopes it would be of the quality of Star Wars. Well...here's hoping for the next one. Interestingly (I've not read it all yet) it appears the movie begins in the real world, then slips into the imaginary one, which is exactly how I always thought it should be. At any rate, this article explains it a lot better than I can.
