Continuity mistake: As noted in another mistake, when Han, Leia and Chewbacca are taken captive in Cloud City, two of the stormtroopers change position between shots. This also happens to some of the other troopers, as well as to Lobot, Lando's aide. This is best seen in the widescreen version.
Revealing mistake: If you closely when Vader cuts through the three poles at the end of the lightsaber duel, you can see that the saber never actually goes through the poles. (01:45:50)
Continuity mistake: Special Edition: Luke cuts off the Wampa's arm at the shoulder, but the limb seen hitting the cavern floor is way too short to be the entire arm. (00:09:30)
Continuity mistake: When the Rebels pick up the signal of the Imperial probe droid, general Rieekan says, "Princess - we have a visitor." In this close-up, his head is straight, but in the next shot, he is standing in a different place, leaning forward. (00:17:35)
Continuity mistake: When Han gets off the taun-taun when he is searching for Luke, the upper part of his jacket and the garment over his chin is covered in snow. In the next shot facing Han, the snow is gone.
Continuity mistake: As Major Derlin and another Rebel officer talk before the shield doors are closed, another officer walks under the starship Leia's standing by. In the next shot, he's gone. (00:11:30)
Continuity mistake: When Vader attempts to turn Luke to the dark side, the wires hanging from the structure that Luke is holding onto change in number and position between several shots.
Revealing mistake: If you look closely when Vader cuts off Luke's hand, you can see that Vader's lightsaber never actually cuts through Luke's wrist, but passes in front of his hand. (01:45:55)
Continuity mistake: When Luke uses the Force to lift a rock, the rock is much higher above the ground in the close-up than in the wide-shot. (01:05:45)
Continuity mistake: When Luke is standing on his hands while using the Force to lift a rock, he is distracted. As he collapses, the rocks on the ground are different and in a different position from the rocks seen in the shot before Yoda says, "concentrate." (01:06:00)
Continuity mistake: When Luke drops down in pain after his hand is cut off, he is not holding onto the pole with his other hand (watch closely), but in the next shot, his hand is now clutching the pole. (01:46:00)
Continuity mistake: At the rebel base on Hoth, the Falcon is being repaired in a hollowed-out snow cave. When Han blasts off out of the cave, none of the debris on the floor or in the cave moves at all, nor is there any effect from the Falcon's exhaust.
Continuity mistake: In the beginning of the scene where Luke meets Yoda, in the shots facing Yoda, his hands and walking stick are positioned in front of his face or shoulder. In the shots from behind him, they are positioned in front of his chest.
Continuity mistake: When the Millennium Falcon is pursued by the Star Destroyers after escaping the space slug and, Han pulls the lever for the hyperdrive. In the next shot from behind, the lever has not been pulled.
Continuity mistake: After the Millennium Falcon has left Hoth and Han is trying to repair the hyperdrive, in the shot after he asks for alluvial dampers, the tool box Chewbacca gives him can be seen in the lower left hand corner. When Chewie takes the box, it is lying in a different position than in the previous shot. As Chewie walks over to Han, he is holding the right side of the box with his right hand, but as he puts it down, he is holding the left side of the box with his left hand. There are also more tools in the box than in the previous shot.
Continuity mistake: When Leia briefs a group of Rebel pilots in the hangar on Hoth, the position of her head changes completely between the first and the second shot. As the second shot ends, she begins to turn around, but in the next shot, she has already turned around. Also, Major Derlin's (the man dressed in grey) head has changed position. (00:23:05)
Revealing mistake: During the escape from Cloud City, watch as C-3PO's head strikes a lamp on the hull of the Millennium Falcon. It bends out of shape.
Continuity mistake: When Luke has the vision of Obi-Wan, the amount of snow lying on his back and arm changes significantly between shots. In some shots, he is covered in snow, in others, most of it is gone.
Continuity mistake: On Hoth, when the rebel troops starts to see the At-ST, there is a shot where rebels take place for the battle and there is destroyed equipment and black smoke in the air, even though the battle has not started.
Continuity mistake: When the Empire ship shoots asteroids in the asteroid field, the first one explodes before the laser even hits it.
Answer: Star Wars being for the young and the young at heart, Han and Leia's relationship unfolds in a deliberately childish manner that kids can relate to and adults will find comedic. Leia is irritated at herself for her attraction to Han, and certainly unamused that Han teases her over it, while at the same time he is not brave enough to admit his own feelings, either.
