Revealing: In many far away shots of the sail barge you can see it is on a dune rather than in mid air.

Revealing: In most shots at the pit of Carkoon scene, it is really obvious that the backgrounds are matte paintings. This is easiest to spot when 3PO and D2 are picked up.

Continuity: When Lando says "Go on, you pirate" his entire outfit is reversed - his shoulder holster strap goes the other way, and his rank insignia changes side too.

Continuity: When Han Solo is frozen in carbonite, he is wearing brown trousers, BUT when he is rescued in Jabba's palace, he is wearing blue trousers with a yellow stripe.

Continuity: On the forest moon of Endor when Princess Leia first meets the Ewok, she takes her helmet off and is holding it in her hand (which frightens the Ewok) in the very next shot she is removing it again to show it to him.

Revealing: As they take Han away, watch Lando. Just before he tilts his mask down so we can see who he is, he whacks his head on the doorway.

Continuity: When Luke is prodded out to 'walk the plank', into the Sarlaac pit, he jumps off the board and springs himself back up. If you watch this in slow mo, you can clearly see that only one hand catches the board and that just by the fingertips, but in the next shot both hands are springing him upwards.

Visible crew/equipment: After the heroes get snared and surrounded by Ewoks on Endor, the Ewoks mistake C3P0 for a god and start bowing. There is one Ewok which only has holes where the eyes and mouth are and you can see the eyes and mouth of the person inside the Ewok costume.

Continuity: The shots at the end of the movie with the emperor are obviously lit from the front. This exposed too much of the emperor's head inside the cowl so it was darkened to make him look more menacing. Look for the added shadow - it looks like someone took a black magic marker and coloured on the film. (This may be corrected on the re-release).

Continuity: When Leia gets shoved on Jabba's belly upon her capture, watch carefully - in the side shot of her being pressed against him, we see her arching back from her master-to-be as he talks. Their faces are a good foot or so apart. However, in the next shot of her, we see her face is mere inches away from him as he licks his lips in horny anticipation.

Audio problem: When they are fighting on the little ships above the big pit, Luke beckons to Leia to get her to swing on that rope with him to safety. Watch closely...he says, "come on", but his mouth never moves.

Visible crew/equipment: When Han is running from the explosion of the shield generator on Endor, you can see his reflection in the plexiglass that is used to protect the camera from the explosion. Since the reflection isn't of Han's back, the plexiglas must be in front of him.

Continuity: When Leia offers the Ewok food, she holds it out in her left hand, but from a different angle it's in her right.

Continuity: When Lando is hanging over the pit, he has gloves on, then he has no gloves, then they're back and so on.

Continuity: When Jabba pulls Leia's chain, there is a long shot as she leaps up onto his throne, and he is holding his wine goblet in his left hand, and pulling her chain with his right. However, in the very next shot (in which he says "Soon you will learn to appreciate me"), the entire frame is reversed. This is evident in Jabba's holding the wine in his "right" hand, his higher-placed nostril (which is normally on the left on his face) is now on the "right," Leia's reversal of her armlet, etc.

Continuity: When Vader ignites Luke's lightsabre, Luke is standing next to a column. When Vader extinguishes the lightsabre, Luke is standing further away from the column. In the next shot, he is standing next to it again. This can only be seen in the widescreen version.

Plot hole: The Rebel task force is suited up in camouflage gear when they land on the forest moon, and walk stealthily to avoid detection. So why then do they bring along a shiny, gold-reflective droid, or fail to at least try to alter his appearance to something less conspicuous?

Continuity: When the guards take Chewie to his cell, you can plainly see that when the guard closes the door you only hear it close. You can see that it is still open.

Continuity: The birthmark on Leia's back keeps changing sides during the 'Jabba' scenes. This seems to happen when Jabba's tail changes sides. I guess the model of him only went one way, so they flipped the negative.

Revealing: Right before Luke leaps from the speeder bike to the scout trooper's speeder, there's a shot showing the front of the speeders. Notice the area surrounding the speeders in this shot. During the rest of the speeder bike chase, the speeders pass through this area several times, even though they are not flying in circles. This can be seen, for example, from the sunlight hitting the ground and the tree on the left side with a bush in front of it. Also, one of the shots where this area is seen is the shot before the speeders pass two more scout troopers, but the background has been flipped.
