Corrected entry: In the scene where Luke is chasing the last Imperial Scout on the Speeder, he approaches two trees with very little room between them. He turns the Speeder on it's side in order to squeeze through them. This would only work if what he is flying is wider than it is tall, i.e. an X-wing fighter. By turning the Speeder on its side, he makes himself wider, giving himself less of a chance to survive the maneuver.
Corrected entry: This is in the "Special Edition" one, in the very last few scenes as the Death Star has been destroyed it shows all the different cities celebrating. I believe it is the shot of Corascaunt city, you can see a Storm Trooper crowd surfing over all the people.
Corrected entry: In one of the scenes where Vader and the Emperor are trying to turn Luke, the Emperor is trying to get Luke to "strike him down" with his lightsaber. Luke finally gets annoyed enough to give it a try, but as he swings down to slice the Emperor in half, Vader suddenly whips out his saber and blocks the blow; then the camera cuts to a nifty closeup of the crossed sabers and the Emperor laughing. However, according to that shot, the Emperor should be dead. Look carefully at the position of the sabers: Vader's (red) is on top of Luke's (green) - a position which should have driven Luke's saber straight into the Emperor's body.
Corrected entry: Look at Jabba: he is slimy, slimy slimy, but only around his mouth, nose, and upper stomach. His arms look dry. When he bats Threepio with his arm, the droid gets a notable amount of green goop on his armor. However, whenever Jabba pulls Leia to himself, he pulls her close; her body gets smooshed against his multiple times, and yet she somehow manages to stay completely dry. Unless there are major - not to mention unmentioned - time shifts in which she either cleans up or the slime dries up and crumbles off, there is no way Leia could stay clean.
Corrected entry: In the scene where the stolen imperial shuttle is flying past the star destroyer the bridge of the ship looks massive, yet in episode 5 the millenium falcon clips onto a stardestroyer's bridge and looks a lot smaller.
Corrected entry: Why does the Imperial Fleet give up as soon as the Death Star blows up? They still have more than enough firepower to wipe out the Rebels' ragtag fleet.
Corrected entry: In the scene where the Admiral of the rebel fleet indicates that the ships should wait for his signal before entering hyperspace to go to attack the death star all of the ships make the jump immediately.
Corrected entry: Look at Leia's sex slave costume carefully in the shot of her hip/hand next to Jabba's twitching tail. Notice how there are no panty lines, right? Then look at the scene of her running to the gun on the Sail Barge - her skirt blows back, revealing a pair of dark panties underneath. (00:21:50 - 00:34:35)
Corrected entry: I think that this is only on the Special Edition version. What is that annoying little black spot on the left side of Emperor Palpatine's face? This takes place while the Emperor is sitting on his throne and talking to Luke (he is looking out of the window) about his friends failure. It is like this error on the side of his hood that the restoring people forgot to edit out.
Corrected entry: During the battle on the skiff, Luke kicks the air and his opponent a few inches away falls back.
