The third movie is supposed to be fairly dark, with a lot of the Jedi getting killed. I wonder if we'll get to see Master Mace Windu biting the big one onscreen?
Last I heard, the editted Obi-wan/Anakin duel clocked in at over 20 minutes. It will be the longest one-on-one sword fight in cinematic history.
In comparison, the Qui-gon/Obi-wan/Maul fight lasted less than 5 minutes onscreen.
