Plot Holes:
When Luke first entered Jabba’s throne room, he used the Force to snatch a gun from a guard, but was grabbed before he could do anything with it. Was he planning to have a shootout in the throne room? Without his lightsaber and with only Lando to help out, he really didn’t think he could win, did he? (R2 wasn’t nearby, so couldn’t have tossed him his lightsaber.) Was falling into the Rancor Pit part of Luke’s plan? If so, it sounds like a pretty foolhardy plan! Was it his intention all along to get Jabba sufficiently riled-up that he’d condemn Luke and company to the Sarlaac Pit? Again, this seems like an amazingly foolhardy plan – while it’s true that R2D2 was quite loyal and trustworthy, was Luke
really betting the lives of himself and his friends that R2 would just happen to be assigned to Jabba’s sail barge and therefore be in the right place when needed?
Granted, Luke was a bit flustered at the time and perhaps not thinking too clearly, but why did he
throw a skull to hit the button that dropped the overhead door on the Rancor and killed it? Why not simply reach out with the Force to push the button? It would have been a lot simpler, and it would have been consistent with his training in the Jedi arts.
After they were captured on the Forest Moon of Endor, Luke and his companions were taken to the Ewok village, where they were reunited with Leia, whom they feared had been lost or killed. Inexplicably, Leia was sporting a new set of clothes and a new hairdo. (Did the Ewoks just happen to have a dress handy in her size?) Why did the Ewoks initially view Luke, Han, and Chewie as potential food, but Leia as an honorary Ewok?
When Vader’s shuttle landed on the Forest Moon, we saw that there was an AT-AT guarding the shield generator. Boy,
that sure would have been handy for repulsing the Rebel/Ewok attack that was to come shortly! Where did it vanish to?
