I wasnt asking why the people would want to rescue Han, I understand those are his friends. Why was Lando a hidden guard? Why was Leia supposed to get caught? what did they serve? Luke was trying to be diplomatic? He stole a gun and tried to shoot Jabba with it. Are we to assume Luke KNEW they were going to be taken to the Sarlaac Pit? Like something out of Dumb and Dumber, "but what if they shot you in the palace". None of it makes sense, its like Lucas filmed himself playing with his Star Wars toys then adapted it to film. I mean, couldn't Luke and co going thru Jabbas Palace cutting *****es down be just as awesome?
Leia wasn't "supposed to get caught." She was sneaking around in the middle of the night and ruining Jabba's trophy because she
didn't plan on getting caught. As for Lando, the first time that we see him undercover, it's watching Chewie being led away, and the second time is when Jabba asks for Han and Chewie to be brought before him, because he's the one who rushes out of the room to go get them. Evidently, he was undercover as Jabba's jail master, presumably so that he could free Chewie shortly after Leia thawed Han, but she was caught, so he stayed undercover.
As for Luke being diplomatic, yes, he was diplomatic twice
before trying to kill Jabba. First, he sent the droids in to deliver his message and as a peace offering; then, in person, he gave Jabba one final chance to make a deal to avoid unpleasantness. As for why Lucas didn't just have him and his friends come in and cut the place up, there are two good reasons: 1) it's not in the Jedi or Luke's nature to just massacre others without trying a more diplomatic approach first, and 2) the utter failure of his plan shows us that Luke is fallible, a little too confident in his abilities, still has things to learn and isn't just a Gary Sue.
Not sure what to make of this, in pretty much every Star Wars movie there is communicating devices being used. ANH, ESB, TPM, AotC and RotS all off the top of my head. Disney ones im not so sure
OK, you're right. I forgot that, at the beginning of ESB, Luke talks with Han through a device on the sleeve of his coat. I was thinking that you meant "why didn't they communicate between the ships and the planet surface?" If you did, then I think that my point still stands, but if you were asking why the separate teams on the surface of Endor didn't have the same communicators that they had on Hoth, that's a fair question, though a bit of a nitpick, IMO. It could be explained by there being no array of "cell towers" on Endor like there could've been around the Rebel base on Hoth to relay transmissions, similar to how our cell phones wouldn't work in Antarctica.
