Full list of Star Wars blu-ray deleted scenes
TFN has released some information on the deleted stuff on the bonus discs. Here's a run-through and some speculation on what they contain.
BTW it looks like this will be all "new" deleted material, not simply a repackaging of the DVD deleted stuff. So you have to own the DVDs and the blu-rays in order to get all the deleted stuff it seems. Anyway:
TPM
Trash-talking droids: When Obi-Wan and Qui-Gon first land on the ship, there was going to be a comic-relief scene with two droids talking about the Jedi.
The Battle is over-Not sure what this one is..but I think it's an extended scene on the Royal starship where the Jedi notice most of the TF's blockade fleet has vanished leaving the droid control ship.
Anakin's return: Anakin landing his starfighter in the hanger bay, to a suprised Bravo squadron. (I think)
Battle on the boarding ramp-some more of the Qui-Gon/Maul fight on Tatooine. Maul follows Qui-Gon up on the ramp and the two briefly resume their duel before Qui-Gon kicks Maul off.
Extended podrace wager-Probably just some extra dialogue.
Bail Organa of Alderaan-Originally, Bail Organa was going to be played by actor Adrian Dunbar and make his appearence in the senate voting against Valorum. (Dunbar was later retconned into Bail Antilles) Of course he was recast with Jimmy Smits in the sequel. Not sure if this is the original Dunbar footage or something they've put together with Smits reprising his role. I would expect the latter from Lucas....
AOTC
Extended speeder chase-Some more of the speeder chase near the beginning.
The lost twenty-We learn more about Dooku's Jedi background in this scene that was cut out of the library scene.
Anakin's nightmare-Not sure about this scene, perhaps an Episode III like vision of Anakin's mother?
Anakin and Ruwee-Anakin chatting with Padme's father (Who appears in Episode III at the end but was cut out of AOTC).
Raid on the Droid control ship-Previously only available as an unfinished/animatic on Starwars.com's premium membership, maybe this will be a better version of the scene. Basically, a squad of Jedi try to take control of the spherical droid control ship, only to realize that the droids have built-in backup systems.
Extended arena fight-Some of the Jedi vs. Droid action cut from the film.
ROTS
Elevator antics-Yes, more silly elevator stuff.
Escape through the hanger-Anakin, Obi-Wan and Palpatine return to the hanger bay to discover that it's a total mess and their starfighters are unavailable.
Changes to the constitution-I think this one might be the Jar-Jar scene that was cut. Not sure though.
Utapau chase animatics-Nothing special here, I don't think.
Mustafar duel animatics-Just more animatics.
Kashyyk animatic-Yes, another animatic.
Anakin kills Shaak Ti-This is an interesting one. In the original film two deaths were shot for Shaak Ti. The first is her getting killed by Greivous, and is included on the DVD while the next has her killed in the temple by Anakin and this will be the blu-ray one. The Force Unleashed game ignored both deaths, and used her in it.
Jedi Imposters at the temple-Clone troopers clad in Jedi robes to fool any Jedi returning to the temple. Of course Obi-Wan and Yoda are wise to this and take out the clones.
Senate Duel animatic-Another animatic, obviously
Yoda communes with Qui-Gon: The missing scene where Qui-Gon explains the Jedi secret of immortality. Presumabely they got Liam Neeson to record the lines while he was doing work on Clone Wars.
ANH
Tosche station-Scene with Luke trying to get his friends to watch the battle overhead.
Old Woman on Tatooine-An old lady yells at Luke as he pulls into Anchorhead.
Aunt Beru's blue milk-Aunt Beru pouring blue milk. Really.
The search for R2-D2-Possibly an alternate shot of the scene where Luke and C-3PO are in the landspeeder, with a quick look at a Tatooine temple similar to Jabba's. This scene used projection but didn't sit well with Lucas.
Cantina roughcut-The rough cut of the scene, with Han and some girl, a British, non-articulated-mouth Greedo, and other differences from the finished film.
Stormtrooper search-Not sure about this one, perhaps old Dewback footage?
Darth Vader widens the search-A version of this scene was dubbed over for the holiday special. Basically Vader consults with Chief Bast about the Tatooine search, and Vader calls Tarkin foolish.
Alternate Biggs and Luke reunion-Possibly includes the scene where Red Leader said he flew with Luke's father.
ESB
Extended Echo Base argument-Some more dialogue from their argument at the beginning of the film.
Luke's recovery-Luke getting a bacta mask cut off by the droid. I think.
Luke and Leia: Medical center-Scene where Luke and Leia almost kiss.....
Deleted Wampa scenes-The scenes with the Wampa in Echo base, with rebels fighting it and also Stormtroopers getting mauled. The creature footage was apparentally not that great so they dropped most of this storyline out of the finished film.
The Fate of General Veers-Hobbie loses control of his snowspeeder and crashes into the cockpit of General Veer's AT-AT, destroying it.
Yoda's Test-Presumabely where Luke is asked by Yoda to cut a branch using his saber, and Yoda says if he were a Jedi the branch would have been in many more pieces.
Hiding in the asteroid-Not sure about this.
Alternate Han and Leia kiss-Presumabely another take of the scene.
Lobot's capture-Not sure about this one...
Leia tends to Luke-Probably more footage of the Falcon's medical bay.
ROTJ
Vader's arrival and reaching out to Luke-Part of this scene we've seen on the blu-ray preview last year. Basically Vader reaches out to Luke while he's building his lightsaber.
Tatooine Sandstorm-The fabled sandstorm scene with the full size Falcon prop and some exposition.
Rebel raid on the bunker-Footage of Han and co. taking on stormtroopers in the bunker
Jerjorodd's conflict-Possibly the scene where Jerjorodd is choked by Vader as he tries to enter the Emperor's tower.
Battle of Endor: The Lost rebels-Possibly just cockpit footage, including the Mon Calamari seen in the teaser.
