Something that I don’t think I ever really got when I was a kid is that we’re supposed to be surprised that the Death Star II is operational. Obviously there’s lines of dialogue that set this up, but when you’re young you pay more attention to the visuals (at least I did), and while visually the second Death Star is incomplete, the weapon part of it is not.
So basically my idea is, what if the Death Star II is missing its dish? So we think there’s no possible way it could fire. But then, suddenly, it fires anyway (out of the recess that should hold the dish).
On a separate ROTJ note, does anyone have any idea how to have the droids get taken by Jabba without playing Luke’s hologram? Could you just cut from them entering the palace to being in the droid torture dungeon? Would that make sense? Maybe recut the scene with Bin Fortuna and add subtitles saying basically “yeah right an audience with Jabba, you two are ours now.”
