In what ways “Revenge of the Jedi” and Leigh Brackett’s Empire Strikes Back different from what we got? Aside from Vader not being Luke’s father in Brackett’s screenplay were there some massive changes? In terms of world building, characters…

Off the top of my head;

• the Rebels hid in a giant ice fortress, supposed to be an ancient abandoned castle of some kind
• A lot more of the Hoth sequences focused on the Wampa attacks on the base
• after leaving Hoth, they went to find Han’s stepfather, a head smuggler who sells them out instead of Lando
• Yoda is called Minch Yoda
• Luke trains with the ghosts of Obi-Wan and his father (not Vader) and Minch Yoda on Dagobah
• Vader is not Luke’s father
• In a different draft, Lando was a clone left over from the Clone Wars

These are all half baked memories and I’m unsure how accurate they are

Doesn’t Ben come back to life in Revenge of the Jedi proving what he said in Star Wars, shall strike me down I shall become more powerful than you can possibly imagine. He returns from the netherworld of the force and joins forces with Luke and Vader to defeat the Emperor. I vaguely remember something about Vader casting himself and Palpatine into a lake of fire sacrificing himself.

The other hope Yoda speaks of is Luke’s sister Nellith, who has been trained in the Jedi arts at the other side of the galaxy. Leia was just a princess / love interest.

To me that is the thing I would like to have seen the most. I very well love Vader being Luke’s father, but the Luke/Leia thing… it still bugs me.

It was contrived. Totally forced and jarring. And Carrie Fisher´s reaction in the movie was underwhelming (even she admitted this in The Making of Return of the Jedi book). Nellith would have been way better. Fortunately the EU did some interesting things with Jedi Leia.
