The early draft of the script for Return of the Jedi was more or less the same as the movie we wound up with, until about halfway in, when it took a 12-parsec left turn into the crazy sector. In the script Luke Skywalker travelled to the capital of the entire Empire, a lava planet called Had Abbadon, to confront Vader in a final duel. He winds up stranded on a rock in the middle of a lava lake, and suddenly becomes aware of someone standing behind him. He turns around to meet ... Obi Wan Kenobi! Obi Wan explains to Luke that he's come back to help him defeat Vader and the Emperor because apparently he could just come back from the dead any time he wanted, which would have been super helpful the first time Luke engaged in a climactic duel against Vader in The Empire Strikes Back. And if this wouldn't have made the audience groan hard enough, the next line in the script is:
Suddenly, Yoda appears beside Ben.
"Be grateful the prequels don't exist yet, or the anthropomorphic fuzzy dildo Jedi would be next."
That's right, the entire cast of dead characters from the franchise return to life in the final scene, so that death in Star Wars would have been about as meaningful as it is in a Superman comic.
So did it culminate in an epic multi-Jedi, lightsaber gangbang? Nope. Luke still winds up dueling Vader alone while Obi Wan and the Emperor watch from the sidelines, offering commentary like it's Mystery Science Theater.
"Do a backflip, nerd!"
