I have no idea if this is even possible, but over on the Starkiller thread about a year ago we talked about during the beginning of ESB, show the DSII being built. I think we put it by Mustafar.
Anyways.

The scene where Vader walks to his shuttle works great with no dialogue at all.

If you keep the wide shot from the SE, there's no reason for Vader to say anything. He's in a foul mood, and striding purposefully to his ride. I just tried it with the dialogue pulled out and it plays fine.

I actually like the new Wampa footage, but the biggest problem is that it shows just how badly compromised they were with trying to make the original Wampa suit look believable in the original production. the Wampa's were originally meant to play a much larger part in the Hoth scenes, but you only have to look at the footage in Jambe Davdar's Building Empire to see how much they struggled trying to make the Wampa suit work on film. I don't know why George didn't replace all of the Wampa shots with the new suit when he first made the special editions, as the new Wampa looks nothing like the original (didn't they have any reference photos of the original prop?)

Especially the initial attack on Luke on his Tauntaun, the Wampa's face just looks like a big static Muppet of the abomnible(?) snowman from one of those cheesy 'Frosty the Snowman' Christmas stop motion animation specials , being thrust at the camera, and the colour and lighting don't even come close to matching the footage of Luke that was shot on location, let alone the sense of scale, and then the big static arm on a stick swats him from his Tauntaun and breaks the creatures neck without any sign of articulation.

then theres that horrible shot inside the cave as the Monster is running towards luke which just screams 'Im an average sized guy in a shoddy looking suit running towards camera with my hands obscuring my face so you can't see how shoddy the suit is.'

as for the 'Wampa was scarier when we couldn't see him' argument, as valid as it may be, the truth is we've known for nearly 30 years what the creature looks like, he only has a brief shining moment in the whole saga. Rather than cutting the new footage of a far more convincing looking Beastie why not try and make the original footage look as badass and scary as the film-makers intended and attempted to in the original production?

It may sound ambitious , and i'm not sure how talented Ady's 3d animators are when it comes to character animation, but judging by what they were able to pull off with the new space-battles and ships, it shouldn't be too hard for them to breathe a little more life into the few quick frames in which the creature is shown. I wouldn't normally bring something like this up, but the original Wampa shots have stood out as some of the dodgiest looking effects in the series since I originally saw Empire as a 10 year old in 1980.

a few more suggestions

After seeing what you were able to achieve in ANH with the new death-star reveal got me thinking how cool it be to perhaps see a brief shot of giant Drop-ships carrying AT-AT's and ground forces deployed from the Star Destroyers and head toward the planet.
I have no idea what such ships would look like, but theres probably some sort of visual reference floating around in the EU, besides it'd give your CG crew a chance to be creative and add a new ship design to the series.

Luke's escape from Hoth always seemed a little too easy to me , how did he manage to avoid running into the Imperial blockade that all the transports had to escape through? or did he wait until the battle was over and the Imperials had packed up and left?
Maybe you could insert some Star Destroyers in the far off background of the shot where Lukes x-wing leaves the planet, so that it looks like he left planet on a different vector to avoid the Imperials. There's also a rebel transport that is taking off at the same time as Luke, so shouldn't it have been his duty to escort the transport past the Imperial ships to safety? especially if he knew an alternate route? maybe the transport and the remaining X-wings could be added into the shot so that it looks like they all got off the planet together and safely?

someone else mentioned that it might be a good idea to see a few more shots of rebel transports getting past the Imperial star destroyers?, perhaps we could see a rebel transport that wasn't lucky enough to get past them getting blown to oblivian, it would heighten the tension especially if it was slotted in and implied that it was the transport that Leia would've been on if she didn't get out on the Falcon, although that probably negates the suggestion I made in the last paragraph.

whatever you can do to make the 'Our first catch of the day' seem less ham-fisted, the line itself is fine, it's just the badly overdubbed delivery that kills it, know any decent voice actors that could make it sound more convincing?

echo someones previous suggestion to add glowing embers to the Wampa's severed arm and the shot of Han cutting open the taun- taun, at the moment it's only really the saddle straps that flame a little when Han cuts the taun-tauns belly open.

some people have also mentioned removing Luke's 'willhelm scream' as he lets himself fall to his doom after the Vader/father revelation, but that was an audio change that only appeared on the 97 Special Edition and was fixed/removed from the 2004 DVD's.
but as Luke is sucked into the exhaust pipe he enters with his head facing up and feet facing down, in the next shot it looks like they have flipped the image upside down and Luke is sliding along the top the tube with his head facing downwards, I'm guessing they flipped the shot so that they could reuse it agan in the same sequence to extend his slide through the exhaust tubes, but it's a jarring transition seeing him suddenly upside down.

"I have no idea if this is even possible, but over on the Starkiller thread about a year ago we talked about during the beginning of ESB, show the DSII being built. I think we put it by Mustafar"

^^ Very interesting idea. It would have to be skeletal though (like in ep. 3)

However I wonder if that would take away the element of surprise when we see the new one in RoTJ?

Maybe I am wrong, but wasn't there also some discussion about having there be three or more death stars in ROTJ?

^^ I think the amount of work it would take to insert Piett and actually make the hangar look different isn't worth it. This is probably an area where Ady could just change it back to how it was originally.

if he does delete it, i hope he includes that scene in ROTJ

Yes, there's an early draft screenplay in which there are three death stars (starwarz.com's Jedi Bendu script archive has it). Very different take on the story than the 1983 version (check the ending too!).

No it shouldn't be the same, voices are not genetic! If you took a set of identical twins and seperated them as tenagers and they grew up in totally different environments for 20+ years they would no longer sound the same (if they even did in the first place). You don't even need to explain this with a voice scrambler or something, there is just no reason for their voices to be the same.

Using Temuera Morrison's voice was just a cheap attempt to link the two trilogies, maybe if his delivery of the lines wasn't so bad then it would be OK, but it is a change that only damages this great film.

Sorry for the rant but this kind of stuff really bugs me. The theatrical version of ESB is great and I think some people here are just looking for things to change just to make it different, that's what Lucasfilm did and we ended up with a worse version of the trilogy.

I love that sketch, it's really funny! The only thing that bugged me was that they were hanging out in the chancellor's office. Like Palpatine wouldn't have taken the 20 years to build a really impressive throne room instead, one that would make the one on the second death star look tiny. But since its a spoof, I guess it doesn't matter.

I like the idea of adding Mas Amedda too, if done right. But no advisors in the hologram, its a private chat and would look wierd.

I also don't think the Jedi ghosts should be added. I understand tieing it to the PT but I think you also has to consider those that chose to watch it in production order. And then they would be very confused. Anyway, this is a bit off-topic since this is the ESB thread so maybe we should postpone that part of the discussion?

You mention Vader being prepped by an advisor before his chat with the Emperor. That was Sate Pestage and it was a deleted scene from the movie. I would really like to se that but even if they filmed it, adywan would probably not have access to it. Its sealed away at Skywalker ranch or something like that.

Anyway, this is the scene I think you're talking about:

286 INT VADER'S STAR DESTROYER - VADER'S CHAMBER 286

Darth Vader stands before a shimmering holographic
image which slowly comes into focus. The image is
that of SATE PESTAGE, Grand Vizier to His Eminence,
Emperor.

VADER
Sate Pestage, I would see the
Emperor. He commands it.

PESTAGE
I must warn you, Lord Vader,
The Emperor is in a foul mood.
He bids you wait. Have you any
progress to report?

VADER
The rebel base on Hoth has been
destroyed. I am tracking down
the survivors.

PESTAGE
The Emperor will be with you in
time.

VADER
I wait at his convenience.

Vader gives the answer:

"prepare to land our troops beyond their energy shield, and deploy the fleet so that nothing gets off the system."

The shield didn't cover the entire planet, so the imperials landed and deployed the at-ats beyond its reach.
