Bingowings said:My feeling about the Vader suits is that a good case could have been made for Vader updating his suit between films if the suit in ROTS had looked quite a bit more retro than the one he wore in ANH. (see the Radical Prequel Redux Thread for details).
Instead we got a very tidy hybrid of all the OT suits which looked more advanced than the one he wore in ANH, which like so many of George's decisions creates more problems than were there before hand.
If someone fixed the ROTS suit the updating theory would automatically correct any continuity issues with Vader in the OT.
Someone else came up with the idea of not even showing Vader in his suit in ROTS; the idea being that if you were to design the Prequels to fit with the Originals (so you could watch all 6 in order and not give away any surprises), then you would have to have Anakin called "Anakin" throughout the entire Ep I-III run and the last we see is him burning up.
That way when Vader makes his entrance in A NEW HOPE, you have no idea he is the same person until EMPIRE and JEDI. It would also help the "helmetless scene" in EMPIRE turn into a clue as to who Darth really is even before he makes his reveal to Luke at the end.
This would also mean that you couldn't show Obi-Wan on Tatooine giving Luke to Owen either, though it could be more dramatic to simply show a ship flying away with Padme's unnamed son, fate uncertain (if the Padme Organa idea is used, Leia would stay behind to continue the family line)
There is a Gary Kurtz interview link on the EMPIRE:R thread that I think everyone should read (as far as what JEDI "could" have been):
Key points:
(1) Vader was continuing in his quest to have Luke join him to destroy and replace the Emperor, but not so much out of conquest so much as a means of atonement.
(2) Leia was to be crowned Queen, as Luke wandered off to find his sister and become a full-fledged Jedi Knight (which would have been the impetus for the next 3 movies)
