Corrected entry: The AT AT'S first scene is where you see them for the first time as four groups and they start firing. However that scene has the AT AT's with red cockpits, but they aren't red ever again. Inside the cockpit, the seats aren't red, the walls aren't red, and the lights aren't red. So the AT AT's red cockpit scene doesnt make sense.
Corrected entry: When Luke cuts off Vader's head in the cave on Dagobah, the head rolls to a stop on the ground. The items on the ground next to the head vary from shot to shot between cuts to Luke. First there are sticks on the ground, then those sticks move to make way for the pieces of the broken mask, then the mask pieces disappear and a large branch appears.
Corrected entry: At the end of the light sabre duel in Cloud City, Darth Vader says "Come with me, it is the only way" and Luke falls off the platform into space. When Luke falls, you can see Vader lower his left hand down to his side, and in the next scene, he is seen lowering his hand to his side for a second time.
Corrected entry: In the hangar in the rebel base on Hoth, Solo talks to Chewbacca, and he replies to Solo in his "language," waving a welding device. In the next shot the camera is on Solo again and then back on Chewie, but now the welding rod is circa half its original length, even though no welding took place meanwhile. (00:04:30)
Corrected entry: On Hoth, in the scene where Luke is getting ready to get in his X-wing and Han is working on top of the Millennium Falcon, Han stops to talk to Luke and asks him if he is OK. There is a small droid that approaches from the right that Han stops to speak to. In the next shot of Han, the droid in the background is moving from right to left and you can see vertical cables being used to move the droid.
Corrected entry: During the Battle of Hoth, some of the Rebels fall down without being shot.
Corrected entry: When Han, Leia and Chewbacca are walking through Cloud City with Lando, when they come around a corner, Lobot (Lando's aide, with "headphones" on his head) walks off to the left. When the stormtroopers enter to cut off their escape, Lobot is back, but he enters from the right.
Corrected entry: When the Falcon hides behind the star destroyer, Captain Needa says he will go and apologise to Vader. But when Vader "accepts his apology," he addresses him as Admiral, which of course is an entirely separate rank.
Corrected entry: When the canopy on the snow speeders is coming down, there's a whirring sound as if there is a motor closing it, but it's actually the gunner pulling on two handles that's closing them.
Corrected entry: In the shot immediately before the AT-AT destroys the shield generator, we see many rebels running from this particular AT. It shoots at one of them, and despite the fact the lasers completely misses him, he falls and dies anyway (best seen in slow-mo).
Corrected entry: When Han, Leia, Chewbacca and Lando are walking through cloud city, Leia is between Han and Lando, and after they round a corner, Han and Lando switch places.
Corrected entry: When Han is evading the Empire and is parked on Veers' star destroyer, the apparent reason they cannot be detected is because the Imperial sensors have a minimum range. However, when we see the point of view from inside the Falcon, there are several more star destroyers hovering around the vicinity. Certainly one of them could have detected the Falcon, or at least seen it blatantly sitting on another star destroyer. (01:14:25)
