Visible crew/equipment: When the Wampa (ice creature) kills Luke's Tauntaun, the end of the "glove" used as the Wampa's arm can be seen in the bottom left corner, as well as the arm of the crew member wearing it. Widescreen version only. Note that this has been fixed on the 2011 Blu-ray release. (00:03:55)
Continuity mistake: In the wideshot where Luke lets himself fall down the pit in Cloud City, Vader lowers his outstretched hand. In the following close-up, he lowers it again. (01:52:10)
Continuity mistake: When Vader cuts through three poles at the end of the lightsaber duel, there are different poles in the shot where he cuts through them and the next shot where they fall. The poles that are cut have a white color, while the ones that fall are dark grey. (01:45:50)
Continuity mistake: When a one-legged 3PO is standing in the Millennium Falcon, begging R2-D2 to fix him, he is holding the severed leg by the knee, with the foot closest to the floor. Some shots later, he is holding it by the foot, with the knee closest to the ground. (01:59:00)
Continuity mistake: When Han and Leia kiss in the Millennium Falcon, Leia's arms are around Han's head in the wideshot, but not in the close-up. (00:49:55)
Other mistake: In the original version, when the Rebel Transport ship leaves Hoth before the ion cannon is fired, an X-wing flies past it, and you can see the transport ship through one of its wings. This has been fixed in the Special Edition.
Continuity mistake: After Luke first sees Boba Fett in Cloud City, he begins to walk away from the corner he is hiding behind. In the next shot, he is closer to the corner than in the previous shot. This has nothing to do with camera angles - notice the distance between him and the wall to his left. Also, his right arm is in a different position. (01:34:55)
Continuity mistake: When Vader cuts through the three poles at the end of the lightsaber duel, Luke is crouching down next to them. In the next shot, he is standing upright. (01:45:50)
Audio problem: When Luke and Vader are fighting in the carbon freezing room, at one point Luke forces Vader off the side, looks around, then jump down himself to look for Vader. Listen to the sound that is supposed to be the sound of Luke's feet hitting the ground; you can see Luke stand back up after jumping over the side in the bottom left corner of the screen, but Luke is almost full stood back up when we hear the sound of his feet hitting the ground. (01:45:20)
Continuity mistake: In the shot where Luke's hand is cut off, there's a large gash in his shirt on his left shoulder. In the following shots, the gash is much smaller. (01:50:20)
Other mistake: In the original version, in the first wideshot of the Super Star Destroyer, on the right side of the screen, the light of a Star Destroyer (but nothing else of it) can be seen just flying through space for two seconds before it disappears. This mistake is fixed in the Special Edition.
Continuity mistake: After Leia, Han and Chewbacca walk down the stairs in the carbon-freezing chamber, as the shot ends, Han is turning towards a stormtrooper behind him. In the next shot, he is turned in a different direction, and Leia's head is facing another way. The position and existence of some of the people around them changes between the two shots as well. (01:31:10)
Continuity mistake: During the escape from Cloud City, Chewbacca is shooting at the stoormtroopers while R2-D2 tries to open the door. The wall he is hiding behind keeps changing between shots, and the burn mark on the wall also changes a few times, without any laser beams hitting it. (01:47:55)
Other mistake: When the Star Destroyers are seen for the first time, in the second shot, some of the TIE fighters that fly over a Star Destroyer are transparent. (00:19:55)
Audio problem: After Han goes to the command centre during the battle on Hoth, Leia says to a controller, "Send all troops in sector twelve to the south slope to protect the fighters," but the words don't match her lips. (00:30:35)
Continuity mistake: When the Millennium Falcon is approaching Cloud City, Leia's hand is on the top of Han's pilot seat. In some shots, her hand is in the middle of the seat, in other shots, it is right next to the middle. (01:18:35)
Continuity mistake: When a blast rocks the command centre during the battle on Hoth, C-3PO is thrown backwards into Han's arms. As the wideshot leaves, Threepio is leaning backwards, supported by Han, but in the next shot, both of them standing upright in a normal way. Toryn Farr, the woman sitting behind them, has changed position as well. (00:30:40)
Continuity mistake: When Chewbacca is choking Lando, as Leia says, "We don't need any of your help.", Lando is standing on his knees. In the next shot, only his head can be seen, but the position of his head and Chewie's arms shows that he is now standing straight up. In the next shot, he is on his knees again. (01:38:15)
Visible crew/equipment: When Luke and Vader are fighting in the carbon-freezing room, in the wideshot after Luke does a somersault, a crew member is visible in the steam on the right side of Vader, moving out of the way. (01:40:50)
Revealing mistake: In the original (not Special Edition): When the AT-ATs are attacking the Hoth base, they do a camera angle from inside Luke's cockpit. As his snowspeeder is passing through the legs of an AT-AT, part of the cockpit becomes translucent and you can slightly see the AT-AT through a metal bar.
Chosen answer: He "searched his feelings" as Vader instructed; he reached out with the Force and felt the truth of the statement.
