Star Wars: Episode V - The Empire Strikes Back (1980)

Visible crew/equipment: A few seconds after Slave 1 (Boba Fett's ship) takes off there's a close-up of R2 and the camera and two crew members are reflected in his head. (01:43:15)

Continuity mistake: After R2-D2 opens the door to the landing platform during the escape from Cloud City, the droid exits through the door. Some shots later, he is back inside. (01:43:55)

Continuity mistake: After Boba Fett's ship takes off, C-3PO yells, "Oh no. Chewie, they're behind you." Chewbacca shoots at the newly arrived stormtroopers and one of them falls over dead, next to the big white sculpture at the top of the stairs. In the next shot, where R2-D2 spins around before going after the others, the stormtrooper's body is gone. (01:43:55)

Catwalk ★

Continuity mistake: When Vader and Luke are fighting in the carbonite freezing room, before Luke falls into the chamber, you can see the doors of the freezing chamber closed. In the next shot you hear the doors begin to open, but you can see that the doors are already completely open. (01:44:05)

Continuity mistake: When Leia and Lando are holding off the stormtroopers while Chewbacca and the droids escape into the Millennium Falcon, a stormtrooper comes running through the doorway. You can see the burn mark on his armour before Lando shoots him. When the trooper is shot, another trooper comes running through the door, also with a burn mark on his armour. Then Leia shoots another (or perhaps the same) trooper, and the burn mark is once again there before the trooper is hit. (01:44:20)

Continuity mistake: During Luke's and Vader's lightsaber duel, Vader says, "Release your anger" and in the next shot their interlocked lightsabers have switched positions. (01:44:50)

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)

rstill

Revealing mistake: When Luke runs into Vader again after being sucked out the window, as they are fighting in the control room, watch closely: Vader's lightsaber hits the wall a couple of times, but the explosions are not where the saber touches the wall. (01:45:20)

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 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)

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: 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)

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)

Kylantha

Continuity mistake: When Vader cuts off Luke's hand, as the shot ends, Luke is standing upright, but in the beginning of the next shot, he has already began to drop down. (01:45:55)

Continuity mistake: During the duel in Cloud City, Darth Vader cuts three pillars with his light saber, just before cutting Luke's hand. The pillars aren't burning after that yet in the following shot, they are burned. (01:45:55)

Dr Wilson

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 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: When Vader attempts to turn Luke to the dark side, he says, "With our combined strength, we can end this destructive conflict and bring order to the galaxy." As the second shot begins, Luke is standing much closer to the structure he's holding onto, than in the previous shot. (01:46:20)

Continuity mistake: When Vader is about to tell Luke that he is his father, as Luke says, "He told me enough," he is holding onto one of the thin poles next to him. In the next shot, his hand is positioned lower down and clutching the other pole. Also, his head is in a different position, seen from the markings on one of the other poles. The position of his head and hand changes in the next shot as well. (01:46:35)

Audio problem: When Lando is punching desperately at the door's control panel in Cloud City, he says "The security code has been changed!" but his mouth doesn't move when he says it. (01:47:10)
