Audio problem: When Luke says, "Now all we gotta do is find this Yoda, if he even exists," if you look closely, his mouth never moves.
Revealing mistake: In the shot where the Falcon is underneath the Star Destroyer, it is transparent and you can see the part of the Star Destroyer through it.
Revealing mistake: After Princess Leia switches C-3PO off and the camera angle switches to a close up of Han and Leia discussing where to go next, you can see C-3PO moving in the background as the actor inside the suit is breathing. (01:16:10)
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.
Suggested correction: The cable is thin and we only see closer in shots until the walker falls, but you still can see it, barely in 1080p, right as the head hits as a line between the top of the front leg connecting to the back leg.
Other mistake: When the AT-AT (Imperial Walker) blasts the shield generator, when it explodes, you can see the glowing remains of it (only visible on widescreen DVD). It was fixed in the 2019 version.
Continuity mistake: When Luke crashes on the snow he tries to open the cockpit pushing the canopy. A shot later he is pushing the windshield. This changes back and forth several times.
Continuity mistake: After Luke's snowspeeder crashes on the snow, right before he exits, there's no damage on the right window. From the outside shot it's broken all over.
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)
Continuity mistake: When the Imperial stormtroopers arrive to prevent Leia, Han and Chewbacca from escaping after being captured by Darth Vader, Lobot (Lando's aide) walks down the steps and stands in front of two of the stormtroopers. When we see Lando saying "I'm sorry" in the next shot, Lobot has disappeared. (01:28:40)
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. (00:37:10)
