Audio problem: When the shuttle Tydirium is approaching Endor, look closely when Han says, "Fly casual" - he begins to say the words before his lips start moving. When he stops talking, his mouth is still moving.
Continuity mistake: In the scenes where the Emperor is trying to convert Luke, watch the stars through the window behind him. The same group of stars go floating past every time.
Continuity mistake: Look at the full body shot of the holographic Luke. Luke, who normally has his lightsaber clipped to his left hip, now has it hung from his right hip. As well, his hair, which normally has a part on his left hand side, is now parted on the right. Afterwards, just before Artoo turns the message off, we get a shot from behind Artoo, and Luke's hologram is visible on the extreme right of the screen. Luke's lightsaber is now hanging from his left hip where it normally is.
Audio problem: In the desert after Luke starts putting his rescue plan into action, Han says "Boba Fett", before hitting him unintentionally. He immediately says "Boba Fett" again. It is the same sound, looped.
Other mistake: On Endor, after Han Solo's group was captured, C-3PO called out to the Empire's soldiers. One of them said "Bring those two down here!" Both C-3PO and R2-D2 were up there, but from the Imperials were standing, they could only see C-3PO. R2 was hidden behind a tree. They wouldn't know that he was there until they actually got close to the two.
Continuity mistake: When Han is speaking to Lando before he departs for Endor, the distance between the two men changes between shots.
Continuity mistake: Before the rebels take off for Endor, Han says to Lando to take the Millennium Falcon as "she's the fastest ship in the fleet". At this point, Lando can be seen moving his head down, but as the scene changes he is looking straight ahead again.
Visible crew/equipment: During Luke's conversation with Ben's ghost, you can see a boom microphone in the background. This applies to the original wide-screen version.
Revealing mistake: When Admiral Piett says "I have orders from the emperor myself," the right edge of the matte can be seen on the right. Theater version only. This has been corrected on the 1997 special edition release.
Other mistake: DVD and Blu-ray only: in the Battle of Endor, right after the rebel fighter says "there's too many of them." The Millennium Falcon goes into 1/4 of the picture, you can see a black square spot on the right side of the flash frame due to a bad filter usage. Widescreen only. It does not appear in the 4K release even though it wasn't removed.
Revealing mistake: When Han Solo lifts his hands up and he spots the Walker that Chewie and two Ewoks are in, one of his hands is transparent, and the trees are visible through his hand.
Suggested correction: They are not transparent. What you are seeing is glare from the bright sky in the background. You can see other ghost images matching the bright white portions of the shot. Besides, there would be no reason for it to be transparent. It appears to be a fully on-location shot with no compositing.
Completely not true. You can see the trees through his hands; therefore, they are transparent.
Look closer. There is a white ghost image that matches the bright white sky, offset to the left and rotated slightly. And why would the hand be transparent? This is not a composite shot.
While it's not a composite shot, that would mean that the shot of the imperial officer yelling "freeze" in the original version wouldn't have been transparent. But it's not a composite shot too, therefore, they are transparent.
This comment makes no sense. What Imperial officer are you referring to and what does it have to do with this shot? And if this isn't a composite shot, which you seem to be admitting, why would the hand be transparent? Do you think Harrison Ford's hand actually became see-through?
Continuity mistake: Outside the bunker the position of the bodies keep changing or moving throughout the battle on Endor.
Continuity mistake: When R2-D2 is shot by an Imperial stormtrooper whilst trying to open the shield generator's doors, he goes into the side wall and you can see a door open on his body with an interface arm sticking out of it. But when Han shoots the stormtrooper dead, we cut back to R2, and the door that was originally open is now closed.
Continuity mistake: When the Rebel fleet is preparing to make the jump to hyperspace to the second Death Star, the small fighters move first. Then the big ships. But when the big ships move into hyperspace, there are only the Medical Frigate, some transports and some Blockade Runners. What happened with the big Correllian command ships?
