This reminds me of reading about George's first intentions to have Obiwan the "main" jedi in TPM for the first act. Then, he meets Quigon at Coruscant I read it here. For a guy that professes that he wants his "original vision" to be seen he does change it a lot.

That idea still steams me about having ObiWan as a secondary character in TPM. Making QuiGon the lead makes the movie all the more irrelevant in the grand scheme of the saga. If Lucas atleast did the supposed force ghost scene with QuiGon in ROTS, it would atleast give some relevance to his character, that he was the was the one who figured out the trick, but we get one stinkin line from Yoda, so Lucas could check off another OT tie-in in the last 20 minutes of the movie.

Kenobi should have found Anakin, and their relationship should have been central to Episode I, thus you wouldn't have to keep showing their friendship in AOTC & ROTS just so people know they are pals. Every relationship should have been set up in TPM, that would give two movies to advance the plot, instead Lucas has main characters QuiGon & Jar Jar who take up major screen time in the movie, and Anakin/Kenobi are secondary until AOTC.
