Unless your counting the clone wars cartoon none of that is explained including his coughing which 95% of those that saw the movie, were like, "what the hell is this crap!" To me it fills in the plot hole better than exists now. The plot holes in the entire saga are so innumerous that it actually, ironically works to the favor of GL by fandom coming up with wild theories to explain all of it. I had thought of doing a clone wars edit as well actually, though this would be last on my list. I am thinking of using some sound bites from it though early on. BTW, Commander Courage...sadly, and wonderfully, I had never seen those tome poems on theat 2nd page of the DVD, very pleasant suprise and a trove of good soundbites for my edit...THANK YOU! Including Maul Dialogue (clearer than whats in the duel of the fates video) I wish I could get someone to catalog movies such as closer with natalie potman or pulp fiction with samuel jackson and see if any audio could link up to the movies. There is a number of aforementioned holes that other drafts of the script really fill in, but is lost on the final movie. I could drive myself crazy doing all of this. I am too obsessive about this.
