i really think it is worth keeping in mind that to an extent the star wars saga as a film series is somewhat removed to the EU (ie expanded universe). they must work well as films in their own right without relying on outside sources. if boba were to be seen escaping from the sarlacc we could be left wondering why he doesnt re-enter the film later on.
the beauty of removing him is that it just removes the question of if he is/isnt dead etc. as escape could just be one of those loose plot lines like the whole sifo dyas thing that wasnt actually explained on film.
ive just watched the dagoba scenes again and its really blown my mind. if/when you ever do the prequels ady, would you modify yodas colouring to fit in more with this? or is that a bit to far off yet?:p either way i am astounded by the improvements!:D
