You make a good point that no good guy characters die, but we lose Darth Vader and the Emporer in one fell swoop with no form of sacrifice from any of the rebel characters.... If Lando was to Die he should still make it out the deathstar II but be on fire which destroys the millennium falcon in a later shot. Like a Big fire ball going down. It would also be symbolic like the flight of the phoenix which in mythology means the start of somthing new.
wiki:-The phoenix has long been presented as a symbol of rebirth, immortality, and renewal.
I think this is possibly a good direction to take. We don't need to worry like Lucus did at the time about the next Movie now we know that there will never be one.No need to show the misery of Han either that's war. Han already looked at it like it was the last time he would see the falcon so this was planned and changed later on probably. But if it stays the same as in the original is good too. Possible music scoring over Lando and the falson's destruction would be the creshendo / dramatic pert of Princess Leia theme, this would also be representitive of Leia's new role after the events that have transpired. There is no way you could destroy the falcon quickly it would have to have a massive impact... It really would need to be made affecting Visually and drawn out.
Cannot remove ewoks... Unfortunatley
Try to play with what dialogue we have of Alec Guiness perhaps there is another line from either ESB or ANH that could help this. I liked the part about "your friends ended up saving you..."
Han solo's Jelousy is Lame the Love triangle needs to go it was already resolved in ESB then re-intergrated into ROTJ when Leia frees Han from the Carbonite "somone who loves you" end of Love triangle IMO and I have tried to show you that it's more interesting to keep Leia in the dark about Luke being her brother... She realises she has power she just has not figured it out yet.
I don't personally feel the need to show celebrations all over the galaxy, But on Endor is acceptable and would be happy for the movie to end with the funeral pyre.
I surprised myself with the rough cut of last act albeit before you pointed out the shield was not down when the executor crashes into DSII, but what do you make of this being lukes exit point? I think you need to do your own rough cut regardless of script so you can see why I chose to do what I did. my rough cut needs a revision in light of your respose as I made a booboo.
Don't worry too much about leaving a loose end or 2 it gives a movie more life after you finished watching it... Most of the best films don't explain everything and leave it up to the audience to interpret meanings or what happens now?....or what about this?... And gives you another reason to Ponder and watch it again.
Hope this helps you out with your script btw happy anniversary!
