Continuity: 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 lightsabre is held in a different angle. This is best seen in the widescreen version.

Revealing: Vader cuts off Luke's hand at the wrist. When Luke is holding on to the antennae-like assembly underneath Cloud City, in one shot, Mark Hamill bends his wrist, revealing the gimmick.

Continuity: The Wampa changes when we see it again in the ice cave. Its fur is less fluffy and its horns are bigger.

Revealing: Just before Darth Vader reveals his true identity, Luke yells, "I'll never join you." and his right hand, the one that got cut off, can be seen tucked under his shirt. This can also be seen when he says, "He told me you killed him."

Continuity: 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: During Luke's and Vader's lightsabre duel, Vader says, "Release your anger…" and in the next shot their interlocked lightsabres have switched positions.

Revealing: The medical ship where Luke, Leia and the droids are in at the end of the movie is transparent.

Continuity: At the fight between Luke and Darth Vader, after Luke pushes Vader to fall down from the top of the hibernating cabin, he looks down with the lighting light sabre in the hand. He goes back and we hear the switch-off sound of the light sabre, he comes back three meters left of the point he looked down and in his hand is the switched-off sabre. But as he goes back before this, we can see the end of the prop-light sabre taken out of Luke's hand and obviously the off-prop sabre is given in his hand.

Continuity: Viewed from inside, the hotel where Leia, Han and Chewbacca are in Cloud City has a flat glass roof, but viewed from outside, it is flat with sloped edges.

Factual error: The view from a Star Destroyer bridge should show the main hull of the ship, all we see here is the vastness of space, even worse is the Super Star Destroyer which is massive in comparision.

Revealing: When Yoda is training Luke by having him do a handstand and stack some rocks, watch closely during the close-up of one of the rocks. You can see a string holding it in the air.

Continuity: When Boba Fett shoots at Luke, he fires his blaster four times. The second shot hits the corner Luke is standing by, but in the next shot of Luke, there is no burn mark there. The only burn mark seen is the one from the third shot.

Continuity: 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.

Continuity: 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.

Revealing: After C-3PO gets shot, as Chewbacca walks over to the door, his right foot crushes one of the steps on a small set of stairs.

Revealing: When Luke is talking to Han over the comlink, there's a shot of Han riding a tauntaun. The animal leaves no tracks in the snow.

Continuity: 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: If you closely when Vader cuts through the three poles at the end of the lightsabre duel, you can see that the sabre never actually goes through the poles. Play it in slow motion for confirmation.

Continuity: 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.

Continuity: 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.
