^I would be curious to see as well. I'm not against making drastic cuts, like the one I suggested for the Obi-wan and vader duel, but I have trouble with the idea of cutting the Rancor because it really is one of the standout parts of ROTJs production design. The sequence overall may be kind of dicey, but so much of ROTJ's ideas feel like a retread, and the Rancor is something trully unique to the movie and is unlike almost anything we've seen before. That's especially true if you cut the unnecessary planet core monsters from Episode 1, leaving the Rancor as the first instance we see a creature of such size and scope.
Maybe in the end it would serve the pacing and Luke's character development better, but I'd definitely like to explore every conceivable option before just cutting it.
