Continuity mistake: The Wampa changes when we see it again in the ice cave. Its fur is less fluffy and its horns are bigger. (00:04:00 - 00:08:45)

Dr Wilson

Revealing mistake: When the medical droid tests Luke's mechanical hand at the end of the film, his thumb moves before the "muscle." (02:00:40)

Dr Wilson

Audio problem: When Chewie is choking Lando, Leia says "We understand, don't we, Chewie?" A shot later, her mouth moves but no sound is heard, and when she says "We don't need any of your help", her voice is heard a little bit after she starts moving her mouth. (01:42:20)

Dr Wilson

Revealing mistake: During the battle on Hoth, after Luke says: "Hobbie, you're still with me?", there's a shot of an AT-ST shooting at the rebel and after that, there a shot of an explosion behind them. You can see that the rebels are actually dummies in that shot.

Dr Wilson

Revealing mistake: When Luke quits Hoth, the planet is actually painted on a glass sheet but the problem is that you can see a line joining two sheets. (00:36:15)

Dr Wilson

Continuity mistake: On Hoth, the hangar's door starts closing twice. (00:11:45)

Dr Wilson

Continuity mistake: When they are escaping from the Hoth base, Chewbacca enters the Millennium Falcon but when Han and Leia enter some seconds later, Chewbacca is still going inside the spaceship.

Dr Wilson

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

Trivia: During the chase in the asteroid field, a TIE fighter is hit by a little one. If you watch in slow-motion, you can see the pilot ejected from the explosion.

Dr Wilson

Revealing mistake: When Luke and Vader are fighting in Cloud City, there is something looking like tape wherever they hit something with their lightsabers. Maybe it's pyrotechnic charges?

Dr Wilson

Continuity mistake: Special edition only: 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. (01:22:25)

Dr Wilson

Revealing mistake: When Darth Vader meet Luke in the Cloud city, you can see the stick used to make the special effects before Vader starts his lightsaber. (01:41:05)

Dr Wilson

Continuity mistake: When Leia, Han and Chewbacca follow Lando for refreshments, there is a window beside them. When he opens the door and they see that Darth Vader is there, there is no window but a painted panel with glass bricks.

Dr Wilson

Revealing mistake: When the Millenium Falcon fakes hitting the Star Destroyer, half of the sky is gray and the other half is black.

Dr Wilson

Continuity mistake: On Hoth, when the rebel troops starts to see the At-ST, there is a shot where rebels take place for the battle and there is destroyed equipment and black smoke in the air, even though the battle has not started.

Dr Wilson

Audio problem: At the beginning, when they close the door of the hangar, it makes no sound on the first shot. (00:11:45)

Dr Wilson

Revealing mistake: Look carefully at the end of the cavern where the Millenium Falcon enters the giant asteroid. It's a dark blue circle, because the light is dim. But there is a little white circle on the right and the two circles are much brighter on the left side. It's because it's an image of a planet with a moon.

Dr Wilson

Continuity mistake: When the Millenium Falcon escapes from the giant space worm, it comes from the center of the mouth, but viewed from outside, it comes from the side.

Dr Wilson

Visible crew/equipment: When the snowspeeders exit the rebel base to go to the battle, there are rails under them.

Dr Wilson

Revealing mistake: During the attack on the rebel base, after the headless AT-AT falls on the ground, another one shoots at the rebels. You can see the pyrotechnic charges where the impacts are. (00:33:05)
