Continuity mistake: When Luke confronts Jabba the Hutt, Jabba says to Bib Fortuna, "You weak-minded fool." In the next shot, Jabba's tail has switched position. (00:22:55)
Continuity mistake: When Luke removes Vader's mask, Anakin's eyebrows have been removed in the 2004 DVD. However, a part of his left eyebrow can still be seen in some shots, and it even changes size a few times. (01:55:50)
Suggested correction: It's not part of his eyebrow. It's a shadow.
Continuity mistake: When Leia wakes up in the woods, she sits straight up. In the next shot, she is still lying on the ground. This is best seen in the widescreen version. (01:00:25)
Revealing mistake: On Jabba's sail barge, Luke's hand is wounded before it is shot at.
Continuity mistake: When Leia knocks out a scout trooper with a branch after being discovered on Endor, she is turning to the right. In the next shot, she has turned the other way.
Revealing mistake: During the speeder bike chase, the speeders never cast any shadows on the ground.
Revealing mistake: When 3PO and R2 are being assigned to their droidly duties in Jabba's palace, there is a shot of a poor droid having hot irons branding his feet. The irons are never closer than an inch from the droid's feet, and the steam that allegedly comes from the burning is obviously being shot out of holes in the droid's feet.
Continuity mistake: When Vader's shuttle is approaching the Death Star, the crew in the control room of the Death Star are wearing black gloves. One of them then reaches forward to press a button, but in the close-up of his hand pressing the button, the hand is not wearing gloves at all. This can only be seen in the widescreen version. (00:02:25)
Audio problem: When Vader is talking to Moff Jerjerrod in the beginning of the film, he says, "Perhaps I can find new ways to motivate them." As he says the last two words, Jerejerrod's mouth is moving as if he were talking, but nothing is heard. (00:04:00)
Revealing mistake: After Wicket tells the rebels where the secret entrance to the base is, there's a shot of spaceships flying in space. An X-Wing passes through the Millennium Falcon and another one through a Calamarian cruiser.
Other mistake: Widescreen version: When Luke and Vader enter the Emperor's throne room, the stars seen through the window behind the Emperor move a little faster than the stars seen through the two other windows. (01:26:35)
Audio problem: After landing on Endor, Han says, "This whole party will be for nothing if they see us.", but his lips hardly move. (00:55:10)
Continuity mistake: After Leia frees Han from the carbonite, she begins to put her hand on his face as she kisses him. As the first shot ends, her hand is on his jaw, but in the next shot, her hand is on his cheek. (00:19:10)
Continuity mistake: At the end of the scene when the Emperor and Darth Vader walks through the Death Star's hangar, you can see that the Emperor walks past a squad of grey suited commanders. But in the next shot there are only white dressed storm troopers and scout troopers on the right side of the Emperor. And if you compare the last shot in the scene with the earlier shots you can see differences in the soldiers' placements. (00:37:45)
Continuity mistake: When Luke pulls Vader away from the edge of the abyss, a wall can be seen behind them, quite close to them. But several times earlier in the movie, there was no such wall in this area of the Emperor's throne room. (01:52:40)
Continuity mistake: In the scene where Leia frees Han from the carbonite, there's a table on the right side of the room. The position and existence of the fruit and other objects lying on and around the table keep changing between shots.
Continuity mistake: When Vader is searching for Luke in the dark, as he says, "If you will not turn to the dark side, then perhaps she will." he is holding what appears to be Luke's lightsaber in his left hand. But when Luke ignites his sabre in the next shot, he somehow has it again. (01:48:10)
Revealing mistake: 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.
Continuity mistake: After the Death Star explodes, in the first shot of the Ewoks, a grey one is standing next to Chewbacca (who can be seen on the extreme right). In the next shot, this Ewok has disappeared, and another one is standing next to C-3PO. This Ewok has disappeared in the following shot, and a third one, who was nowhere to be seen in the previous shot, is now standing in front of Chewbacca. Also, C-3PO, Chewbacca and the Rebel next to him are standing in different positions between shots. (00:58:15)
Continuity mistake: During Luke and Vader's conversation on Endor, as Vader says, "That name no longer has any meaning for me," he is pointing the hilt of Luke's lightsaber at Luke's chest. In the next shot facing Luke, the hilt is nowhere to be seen, even though it should be, because of its position in the previous shot. (01:20:35)
