Continuity mistake: After Luke is sucked out the window, he grabs hold of two bars in a railing, and his right hand is above the left one. As he hoists himself up in the next shot, it is the other way round: his left hand is above the right hand.
Continuity mistake: During the battle of Hoth, Wedge flies a full circle around the AT-AT walker and when the walker begins to fall, you can see the cable around its legs, but in a side view of the walker falling, the cable is nowhere to be seen.
Continuity mistake: When Han attempts to shoot Vader, Vader deflects the bolts into the walls. As he says, "We would be honored if you would join us," you can see burn marks by the door and on the wall to the left. Two shots later, the burn mark by the door has changed shape and size, and in the last shot of the scene, the other one has disappeared. (01:25:05)
Continuity mistake: Widescreen version: When Luke and Vader are fighting in the carbon-freezing chamber, as Vader says, "Only your hatred can destroy me.", the hose hanging from the ceiling behind Luke is pointed straight down, but in the previous shot, it was bent. This has nothing to do with camera angles - watch the smoke coming from it, it changes direction as well. (01:40:40)
Continuity mistake: When Vader addresses the bounty hunters, Piett says, "Bounty hunters-We don't need their scum.", and starts walking towards a corner. In the next shot, he is already at that corner. (01:03:20)
Continuity mistake: During the first scene in the lightsabre duel, Luke is holding his lightsabre in different angles between shots, depending on the camera angle.
Continuity mistake: Just after the Falcon leaves the hangar on Hoth, we see Luke watching the Falcon as it rises up into the sky. Look closely at Luke's head - he is looking at a point ahead of where the Falcon actually is. (00:35:45)
Continuity mistake: During the lightsabre duel, Vader hooks Luke's lightsabre out of his hand. When Luke summons it back to his hand, it is not lying in the same place as it landed. This can be seen from the lines on the floor.
Other mistake: After Vader cuts through a pillar with his lightsabre in the beginning of the duel, the hole in the pillar is much bigger than it should be. (01:37:35)
Continuity mistake: During the battle of Hoth, the weather keeps changing between shots. The sky alternates between being totally clear of clouds, clear with some clouds, and very grey and overcast.
Revealing mistake: After Luke escapes from the snow monster, he collapses, and there's a shot of Han riding. When the camera pans down, there are no tracks in the snow where the tauntaun just ran. (00:11:00)
Continuity mistake: When Han punches Lando, Lando's cape stays on his back, but in the following shots, it's folded over his arm., before he puts it back on again. (01:29:45)
Continuity mistake: When Luke crash lands on Dagobah, the view through his cockpit is crystal clear. But when the canopy pops open, the glass is dark tinted. (00:39:45)
Continuity mistake: When Lando invites Han, Leia and Chewbacca for refreshments at Cloud City, we see a box containing C-3PO's remains and the head of C-3PO is looking to the right. But when the four of them leave the room, we see a close up of C-3PO's head and it is now looking to the left.
Continuity mistake: Widescreen version: In the shot where Luke's hand is cut off, two of the poles that Vader just cut through can be seen in the lower right hand corner. The poles are much closer together than in the rest of the scene. (01:45:55)
Continuity mistake: When the Falcon is being pursued by the Star Destroyers after escaping Hoth, C-3PO enters the cockpit, attempting to talk with Han, but the ship shakes and he lands on Chewie. After Han says to check the deflector shields, Chewie pushes C-3PO off him, though C-3PO leaves his hand on Chewie's shoulder. In the next shot, C-3PO is suddenly standing at the other end of the cockpit, with his hand nowhere near Chewie.Casual Person
Continuity mistake: Before Han is frozen in carbonite, you can see there is nothing by Leia. When the platform Han is standing on begins to drop, we return to Leia and she now has an Imperial stormtrooper standing by her.
Continuity mistake: When Han says "Watch this!" when trying to get the Millennium Falcon to jump into hyperspace, C3PO turns his head around twice.
