A NEW HOPE
-When Vader boards the Tantive IV, have the original music lead into a strong rendition of the Imperial March, and when he pauses to survey the carnage, a lighter version. The Imperial Motif theme would now be the Death Star theme, and reserved only for it.
-Eliminate shot of R5-D4 after he explodes. (Already corrected: Darth Editous)
-Music change: In Obi-Wan’s house, when Vader is mentioned, the low, slow, ominous version of the Imperial March.
-Dialogue change: “I wanted you to have this when you were old enough, but your uncle wouldn’t allow it.”
-Re-rotoscoping Anakin’s lightsaber to match PT special effects.
-Removing some of the more ridiculous SE aspects of Mos Eisley.
-Wolfman back in instead of goofy replacement aliens.
-I don’t know if it’s possible to alter the shot of Ponda Boba’s arm so there is no blood, but if there is that is a must.
-Han shoots first.
-No Jabba scene.
-Re-rotoscoping Luke using Anakin's saber on the Falcon.
-Eliminate Vader's gesture when there’s no line when he’s talking to Tarkin. (Already corrected: Darth Editous)
-Insert faint Imperial March when Vader is walking through the Death Star halls.
-The Duel: Re-rotoscoping the lightsaber when necessary (activation, cores, etc.). Music change: When they first confront each other, some low, omnnous music. This transitions into Battle of the Heroes when the duel begins. The Force theme plays during Obi-Wan's "You can't win Darth..." General re-editing: Cut the really slow part where they’re stumbling around stabbing at each other. Move Vader’s “you should not have come back” to later in the duel, as that shot needs to be reversed ; Vader’s chest plate is backwards. This spreads out the dialogue too. The music of the Order 66 in RotS plays over Obi-Wan's death and their escape instead of Princess Leia’s Theme. There's a very cool re-edit of the duel I saw that uses these muscial cues. I saved it and I'll upload it for your viewing pleasure later.
-Obi-Wan’s death: Face added to robe in final shot. (Already corrected: Darth Editous)
-Update the graphics on the Death Star. (Already corrected: Darth Editous)
-We can discuss incorporating Palpatine and Bail into the movie. Before I thought there was not way to accomplish that in a fan edit but techniques are getting to a point where it just might be possible.
-If we find it impossible to insert Palpatine in any other way, ADigitalMan’s easter egg after the end credits is a must, and might work regardless.
So there's my general outline for ANH. This doesn't address any of the newest suggestions such as Obi-Wan telling Luke the real truth and all that, but it's a start.
