Continuity: In the trash compactor, Han says, "One thing's for sure, we're all going to be a lot thinner." In the next shot, Han and Leia are both standing in a totally different position. For example, both of them are looking in another direction, and Han's left hand is in a different position.

Continuity: In the trash compactor, after the dianoga roars, there's a close-up of Leia standing straight up, with her arm over the large iron pole. In the next shot, she is crouching, and her arm is underneath the pole.

Other: Lightsabre blades have no shadow, but when Luke is practicing with his lightsabre against the remote, just before Ben says, "Remember, a Jedi can feel the Force flowing through him", if you look closely, you can see the shadow of the blade on his left arm.

Continuity: After Vader kills Obi Wan, he turns and starts to walk away down a corridor. A few shots later, Vader is back, stomping on what remains of Obi Wan's cloak.

Continuity: When they are searching for the monster in the garbage compactor, the garbage is shaking, except in one shot.

Revealing: When Wedge leaves the Death Star trench, the green screen is visible behind him for a few frames.

Revealing: Special Edition Only: In one of the new Mos Eisley scenes, the speeder goes down a road with two Stormtroopers on each side. The troopers are just mirror images of the ones on the other side of the street. Their movements are exactly the same.

Continuity: When Han is about to fire his blaster at the door of the garbage compactor, Chewie moves away from the door. In the next shot, he is back in his previous position, and moves away from the door again.

Continuity: After Luke is attacked by the sand people, a shot shows that his head is laying to the side. In the next shot, its facing straight up.

Continuity: When Luke and Obi-Wan are talking to Han in the Cantina, the black cup on the table is sometimes standing right by Han's hands, and sometimes right next to Luke, depending on the camera angle.

Revealing: Many times during the film, when someone shoots with a blaster, the shot does not came from the gun. A good example is in the detention block of the Death Star. Luke shoots and the laser comes from 10 centimeters over the gun. Special edition.

Continuity: When everyone is getting in fighters for the final battle, they all have white helmets with blue insignias. However, they aren't wearing them when they're flying.

Factual error: After the Death Star, when TIE fighters are attacking the Millennium Falcon, each time one explodes at high speed, the debris and the fire does not keep moving.

Continuity: In the trash compactor, as Han says, "I've got a bad feeling about this", Leia's arm is held straight, but in the next shot, it is bent.

Continuity: When Luke first tries his father's light saber in Ben's house, it has a blue color but when he is practising on the Millennium falcon, it now has a white or sometimes light blue color. It has nothing to do with lighting because light sabers always have a bright color in the rest of the movie, even in the darkness.

Continuity: When Owen is talking to C3PO, the droid has a wire coming form his head to his back. It's not there in the rest of the film.

Continuity: When Tarkin meets Leia in the Death Star, he touches her chin at a certain moment. His arm is bent, but it's impossible because he is too far from her in the previous and the next shot.

Revealing: When Luke is first practicing with his lightsaber on the Millennium Falcon against the remote, the zapping blasts that it sends at him are in 99% of the case headed nowhere near his body, but disappear in line with it [very poor FX work] and he flinches.

Audio problem: When Luke, Han, Chewie, Ben and the droids are in the control room, and Luke says "but they're going to execute her," watch closely: his mouth doesn't move for half the sentence.

Continuity: When Luke and Obi-Wan enter Docking Bay 94 in Mos Eisley, as the first shot ends, C-3PO is turned to his left and is standing right behind Obi-Wan on Obi-Wan's left. In the next shot, Threepio is turned to his right, and is standing further away from Obi-Wan, behind him on Obi-Wan's right.
