Perhaps it was 13 minutes I cant remember exactly, ill have to look it up, they did say it would be the longest in cinema history (outside of joke films anyway I guess). I think its an awesome idea, one of the very, very few highlights of the new ones was the fight between Darth Maul and Obi/Qui in the first one. Im sure it will be cut with other action, like the end fight in Jedi, so it wont be just a continuous fight.
Fighting = No acting = Better chance at movie not sucking due to the incompetence of the actors, George and all the other people afraid to tell George the acting, script and directing are atrocious.
