Random thoughts while watching the rough cut:
I like the idea of the opening scene but as the main characters aren't included I think it needs to be a lot shorter, something more reminiscent of the first scene of Empire
I like Yoda handing Luke the green crystal for his lightsaber
I'd cut the exposition scene of the droids walking to the palace, cut from deleted scene to them getting to the big door
I fear you're biting off more than you can chew with this edit; some seriously ambitious stuff in the first few minutes that will take uber cgi and compositing skills
Jabba's 'What is it' should end with a ?
Less Salacious frikkin' Crumb would be better
I like the idea of Palps' new first scene
I'd make lots of cuts to the Jabba sequence to make it seem less kiddy, Han less lame and the whole thing a bit pacier
Interesting use of the sandstorm scene, works well
Surprised to see the Wicket/Leia scene - it's usually about the first thing editors cut
Just thinking out loud here: I wonder if there's some way to make Threepio's story to the Ewoks more cinematic, maybe with flashbacks or something
Not sure about the ROTS flashback - if one of the themes of the film is Vader wrestling with how he's been dehumanised etc, the theme should be established in act one
I don't think the Skywalkers' shuttle landing in the DS hangar bay is necessary - it reminds me of Lucas' bad changes to Empire
I like the shot of the Falcon's turret window looking out on star destroyers during the battle, although it's unclear who's in there using the gun
If you're gonna cut out ghost Anakin you should probably crop the shot so Yoda and Obi Wan are centre frame
I don't think the ending works, it doesn't really go anywhere; probably better to end on Endor
Interesting edit, gonna be a lot of work to get some of these concepts fleshed out. I'd personally choose to cut a lot more childish Jabba and Ewok stuff - but since it's well beyond two hours now I think that's possible and it'll still clock in around a couple of hours.
I also think the Fett storyline doesn't make much sense - he's in the opening scene working for the Empire, then goes to Jabba's palace, then gets his head chopped off. I still think it's best that he's not in the film, as he doesn't really do anything, and has no arc at all.
An idea off the top of my head: there are a couple of fan films with decent footage of Mandalorians attacking stormtroopers in a forest, so what if somehow the rebels paid the Mandalorians to fight for them as mercenaries (think: the ghosts fighting for Aragorn in ROTK) and during the battle Fett died as a kind of anti-hero, then he would have an arc that could work. But I imagine that would be better in a non-Ewok cut.
Anyway, good luck!
