Continuity: When the Emperor is torturing Luke, in the shot after Luke groans, "Father, please", Vader and the Emperor are standing further away from each other than in the previous and following shots where both are visible. (Time)

Revealing: During the speeder bike chase, the speeders never cast any shadows on the ground.

Continuity: When Vader's shuttle has landed inside the Death Star, behind the stormtroopers on the left side, there is a large structure. But when Vader and Jerjerrod, the Death Star commander, pass these stormtroopers, the structure is no longer there. (Time)

Continuity: 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. (Time)

Continuity: In the first shot of the hologram of Endor and the Death Star, the Death Star orbits Endor in an counter-clockwise direction. In the subsequent shots, the Death Star orbits in a clockwise direction.

Continuity: Widescreen version only: when Darth Vader (Anakin Skywalker) dies, the chin part of his helmet is missing in the last shot. (Time)

Revealing: 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. Submitted by Dr Wilson

Revealing: Look at the ewok that first meets the Princess. You can see the actor's normal pink thumb sticking out of the costume while he is holding the helmet. (Time)

Continuity: When Lando says goodbye to Han, after Ackbar's speech, Lando's lapel pin/medal swiches shoulders several times. (Time)

Continuity: In the scene of the rebels planting explosives in the bunker, the first shot shows someone with gloves planting an explosive. Then it cuts to a wide shot of Han's team and none of them are wearing that style of glove. (Time)

Continuity: When they get ambushed in the shield generator complex, an imperial in black appears from the right of the screen in front of the ledge with the railing. Han throws the container in his hands at the imperial. If you notice, the imperial actually begins to jump over the railing before the box even hits him.

Continuity: When Bib Fortuna attempts to persuade R2-D2 to show him the message to Jabba, his hands keep changing position between shots. (Time)

Continuity: When Vader is driven to his knees during the duel, his elbow is over the handrail, but when Luke cuts off his hand, Vader's wrist is lying over the handrail instead.

Revealing: When Vader's shuttle lands on the forest moon of Endor, an Imperial AT-AT walks near the landing pad. There's a strange shadow that keeps appearing and disappearing on one of its leg. Maybe the shadow of the puppeteers? Submitted by Dr Wilson

Revealing: When Darth Vader lands on the forest moon of Endor, he exits the shuttle and his head passes through it. Submitted by Dr Wilson

Continuity: In the beginning of Luke and Yoda's conversation, there's a cauldron hanging over the flames in the fireplace. In the shots facing Yoda, it is hanging higher up than in the previous shots. (Time)

Other: In the original version, when the Rebel fleet reaches the Death Star, Lando says, "Fighters coming in" and the Millennium Falcon flies towards the screen. If you play it in slow motion when the Falcon leaves the screen, you can see two white figures shaped like TIE fighters on the Falcon's underside. As the Falcon leaves the shot, they disappear. This has been fixed in the Special Edition.

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.

Continuity: At the end of the scene when the Emperors 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. (Time)

Revealing: When the shield generator explodes, a piece of shrapnel flies towards the left side of the screen and then flies back, because it bounces off the inside of the building the miniature was housed in. (Time)
