Continuity mistake: When Luke is attacked by the ice creature all the scars are on the right side of his face, but right before he talks to Obi-Wan you see a big scar on the left side of his face, then when he talks to Obi-Wan you can see there are no scars on the left side of his face. (00:11:00 - 00:13:05)
Continuity mistake: When Lando releases Leia and Chewbacca, as Leia says, "What do you think you're doing?" her body is turned in a different direction from the previous shot, and she's holding the blasters differently. (01:37:55)
Continuity mistake: When Janson (Wedge's gunner) fires the harpoon at a leg of an AT-AT, in the first shot of the snowspeeder flying around the AT-AT, the speeder casts a shadow on the snow. In all other shots of this sequence, there is no shadow of the snowspeeder.
Continuity mistake: During the escape from Hoth, C-3PO is far behind Han and Leia as they are running to the Millennium Falcon after the cave-in blocks their path. When they reach the door, he is much closer to them. (00:32:40)
Continuity mistake: When the Millennium Falcon is being chased by the Empire after leaving Hoth, C-3PO's position in the cockpit keeps changing slightly between shots. At one point he falls towards Chewbacca (with both arms in that direction) but during the in-between cut to Leia, he is also still there (with his left arm extended her way).
Continuity mistake: When Yoda is teaching Luke, he is strapped to Luke's back in a rucksack. When Luke puts Yoda down, the little Jedi master is still inside the bag. Luke then reaches for his jacket, and in the next shot of Yoda, he has in a few seconds managed to get out the bag and is now sitting next to it. He is not even sitting in the same place as in the previous shot, and is also holding a walking stick he didn't have when Luke put him down.
Continuity mistake: When the stormtroopers push Leia into the cell in Cloud City, she is wearing a completely different outfit from when she was taken captive. (01:25:20 - 01:28:35)
Continuity mistake: In the shot before Luke's hand is cut off, his left arm is bent and his elbow is positioned next to a pole. In the next shot, his arm is straight and his elbow is next to a different pole. Also, his lightsaber is held in a different angle. This is best seen in the widescreen version. (01:45:55)
Continuity mistake: As already noted in another mistake, when Han is about to be frozen in carbonite, his jacket appears and disappears between shots. This jacket can also be seen when Lando says, "You're being put into carbon freeze." This shot was not fixed in the DVD. (01:35:05)
Continuity mistake: In an exterior shot in Cloud City, Leia can be seen through the window of a building, with one hand on her hip and the other arm at her side. In the following interior shot, her hands are clasped together.
Continuity mistake: When Han and Leia are bickering in the corridor on Hoth, Han says, " Well, the bounty hunter we ran into on Ord Mantell changed my mind." In the next shot, behind them, there's a man walking past them that wasn't there in the previous shot. (00:05:55)
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.
