Hey Possessed. I just found this thread and got excited about your edit.
I LOVE the idea of cutting the first Ewok scene with Leia. I've dreamed of what that would achieve-- it would definitely pick up the pace at that point and keep our focus on Luke where it belongs.
This is probably too late, but I had some other ideas that might suit this project:
1. What if the first things we see in Jabba's palace wasn't from the droids, but was actually the capture of Chewie and failed rescue of Han?
This would improve the "plan" that Luke et al seem to be enacting. My question has always been-- what if Leia succeeded? How would they get Chewie and the droids? Or was Leia's failure part of the plan? Anyway, starting with Chewie gives the plan a more logical escalation and gives Jabba a stronger sense of menace.
This would mean cutting around 3p0 for that scene. Use subtitles to replace his lines. Then I'd cut to an even whackier idea:
2. What if Luke's trip to Degobah came next? Luke isn't on Tatooine yet, he's busy with another errand first-- Yoda. This would get us right into the main story earlier and remove a big kink from the storyline that occurs when this scene is saved for later. The idea that Luke would go to Yoda before saving Han would indicate the level of pain Luke is still going through over his fight with Vader.
Both of these changes would bring a dose of darkness to the opening of ROTJ. In my mind, that brings it closer into alignment with ESB.
After Luke leaves Yoda and Obi Wan, we would get the scene of the droids walking up to Jabba's palace and the stage would be better set for their scene, the death of the first dancer, and then Luke's arrival and the reveal of Leia as Jabba's new bikini girl.
3. A minor note is that I would certainly recommend cutting the chatter between Han and Luke as they ride out to the Sarlaac pit. There is way too much "humor" that both falls flat and deflates the tension in that sequence.
I know you most likely want to finish your edit and I'm not sure why these ideas would make you want to hold off-- but I offer them in case they can be of any use.
I love what I'm seeing here and thanks for all your hard work!
