Theforce.net is reporting that George Lucas is thinking of changing/updating the original trilogy once episode III is done. I'm not sure if it's all even true, but oh well. Below are the rumored changes and my comments on each.

Episode IV: A New Hope

01. The Imperial March has been added to Darth Vader's first appearance on Princess Leia's ship.

Very cool. Necessary, if you ask me.

02. When Obi-Wan is talking to Luke about his father Anakin's Theme plays in the background and then it turns into the Imperial March as he talks about Vader.

Good change.

03. The lightsaber effects have been redone and the frame jumps of lightsabers being turned on has been removed.

Necessary. There are too many times during the Obi-Wan/Vader duel where the saber is barely even colored.

04. There's a new scene which has been shot during the filming of Episode III in which the Emperor dissolves the Senate.

Cool, but shouldn't be too long or it'll distract from the story.

05. In the Cantina, the Duros (green aliens guys) have been replaced with Neimoidians and some aliens from the prequels have been added.

Not really necessary, but it shouldn't be too bad.

06. The bleeding arm on the floor in the Cantina has been replaced with a non-bleeding arm because it's now canon that lightsabers cauterize wounds.

That's cool. It's probably the only blood in the entire Star Wars saga, and that's a weird shot to begin with.

07. The original shooting scene between Han and Greedo has been restored.

GOOD.

08. Jabba the Hutt has been given a makeover and Han no longer steps on his tale.

Improvement.

09. In place of R2 wobbling down the stairs to the Falcon's hangar, a CG R2 navigating the stairs like he does in Attack of the Clones was added.

Cool.

10. The white boxes around space ships have been removed and new CG shots have been added.

That's good. They're distracting at times.

11. The scene of the Falcon being chased by the two Star Destroyers was modified. The Falcon now does spinning moves, avoiding the Star Destroyers' fire.

Very cool. One of my favorite SE changes was the Falcon during the escape from Mos Eisley and the end Death Star battle where the falcon swoops away after taking those TIEs off Luke's back. Much better than the original shot where it just kind of floated up out of frame.

12. When the Death Star destroys Alderaan there's a new scene of Yoda's reaction to the disturbance in the Force that is created by all those deaths and then it cuts to Obi-Wan reacting to it as well.

I'd rather have Yoda's first appearance inj the OT be where it is now, in ESB.

13. The Dianoga has gotten a CG makeover and were are now able to see more of the creature.

Cool.

14. The Death Star's paneling and computers have been slightly altered to show similar displays to those in the prequels.

That should be neat.

15. The words "Tractor Beam" with Aurebesh lettering.

And there goes the only time english lettering is used in the Star Wars movies. :)

16. More stormtroopers have been added to the Death Star.

Necessary, if you ask me. Makes more sense for there to be more than there were.

17. Temuera Morrison's voice is being recorded for use with all the stormtroopers.

This kind of kills the EU notion that stormtroopers were all human conscripts from worlds conquered by the Emperor...there might be an out though, because maybe the Empire ran out of clone troops at one point and had to start conscripting.

18. The Obi-Wan/Vader duel has been spruced up. It is much more epic and there is much more movement. A modified version of Duel of the Fates is being considered for the scene.

How they're going to do this, I have no idea. I guess they could CGI-up Obi-Wan but I think that'd look silly. The fight as it is though, is kind of odd because it's not really fancy or anything.

19. The Death Star plans that are taken from R2 have been updated. When the Rebels are reviewing the Death Star plans they look similar to the plans we see in Attack of the Clones.

The current graphic that they show is pretty poor, and also inaccurate. This should be nice.

20. The Death Star battle is much more epic with more Tie Fighters and more Rebels being blown to bits. We get to see old Naboo starfighters being used by the Rebels.

I'm all for making the fleets bigger in every space battle.M

21. There's a new scene (shot during Episode III) where Darth Vader goes to Coruscant and lands his ship in the same building Count Dooku does at the end of Attack of the Clones. Except now the building is all fixed up and it is now Palpatine's palace. He meets with Palpatine to ask for forgiveness for his failure and inform him of a new potential who is strong in the Force.

Ok I guess.

22. Chewbacca now gets a medal.

Heh...he deserves it!

I'll do the (rumored) changes to the other two movies later on.

EU=Expanded Universe (books) OT=Original Trilogy
