I think that the biggest problem with RotJ is the pacing, the movie can become very dull and dragged down by overly long scenes. George was always big on saying that a movie was made in the editing room and I've been thinking how you could rearrange or cut scenes to make RotJ stronger. The movie starts with a rather pointless scene of Darth Vader talking to a random Imperial, this should be replaced with the scene of the Emperor arriving that is later in the movie. The Jabba sequence goes on far too long and that's mainly because the same theme of someone showing up at Jabba's palace and getting captured happens three times, the entire Jabba sequence should begin with Luke coming through the door, everything prior to that was superfluous and should be cut. After the Leia/Luke speeder bike sequence we get another action scene of Leia and now Wicket fighting stormtroopers, that action scene should be cut, the speeder bike sequence was enough and all that scene needs is Leia meeting Wicket and communicating with him. The entire scene of Luke meeting ghost Obi Wan should be removed, it's just an exposition dump repeating what was said in the Yoda scene but more directly. Endor really drags but the only thing I can think of that really demands cutting is the pointless sequence of R2 trying to open the bunker and then getting shot. Any other editing ideas?
