Audio problem: In teh French version of the film, Han Solo tells Obi-Wan and Luke to go to hangar 49. 94 is written at the entrance.

Visible crew/equipment: After the attack on the Death Star, when the pilots return to the base, the camera crew is visible on C3PO's body.

Continuity: If you watch Leia while they're in the garbage compactor, her belt, at various points, has fallen down around her thigh. It moves from her thigh to her waist (depending on the camera angle) during the whole scene.

Continuity: Luke is on the Millennium Falcon practicing with the floating orb. When he is done, he goes to shut off his lightsaber and as it turns off he jumps to the right due to a dodgy edit.

Revealing: For this one, you will need a LETTERBOX copy that is NOT the special edition.  In the final award scene, there is a long shot of Luke, Han, and Chewie walking through rows and rows of Rebel Troopers.  If you look quickly, the troopers on both ends of the screen are cardboard cutouts.  They are cropped off in the Pan and Scan version, and digitised in the special edition, so its got to be the right copy to see this mistake.

Continuity: Widescreen version only: When Luke activates his new lightsabre for the first time, the position of C-3PO's head is different from the previous shot. After he turns it off, Threepio's head is back to its original position.

Continuity: After the droids land in the desert C3-PO has a streak of oil running down his left shoulder. A couple of scenes later when he is walking after he splits up from R2-D2 there is a long shot of him and he still has the streak on his left shoulder. There is an immediate close up and the streak switches to the right shoulder.

Other: Drewe Henley, who plays Red leader, is misidentified in the credits as "Drewe Hemley."

Continuity: When Leia is recording her holo-message to Obi-Wan Kenobi, she pushes a button on R2D2 to finish the message but each time we see the actual message during the film, she turns a huge round button.

Continuity: In the beginning of the first scene of the duel between Vader and Obi-Wan, their lightsabres are held in different angels between several shots.

Continuity: In the opening shot of the movie, sunlight strikes Tatooine from above, but hitting the two moons from the left.

Continuity: When the walls of the trash compactor start moving, Han is holding the pole, and leans it against the wall to his left (we hear it hit the wall). In the next shot, the pole leaning on the wall to his right instead., and the right side of the pole moves up and down between the next few shots.

Revealing: During the escape from Mos Eisley, when Han says, "They're gonna try and cut us off", he grabs the control panel in the cockpit, and the whole panel lifts off the floor.

Revealing: When Luke ignites his new lightsabre in Ben's house, the reflection of the stick used during the filming is visible on C-3PO's body.

Other: When the stormtroopers stun Leia, if you play it in slow motion, you can see that she begins to fall before the beam touches her.

Other: In two close-ups of Han before he jumps down the garbage chute, you can see make-up smeared on his stormtrooper suit, under his chin.

Other: Just before Darth Vader enters the Blockade Runner, there are some kind of tiny white-green lasers in the air. They are sometimes in line with the normal red ones. The stormtroopers and the security guards of Leia are both using red lasers, so there is no reason to see green ones.

Continuity: When the rebel leaders are studying the tactical illustration of the Death Star, it shows a large, round indentation positioned at the Death Stars equator. The Death Star actually has a smaller, round indentation in its northern hemisphere. Can't be due to intentional differences between the plans and the finished thing, otherwise the rebels would have no way of knowing that the vulnerability was still there either.

Continuity: When Luke and Obi Wan arrive at the Cantina, watch the Jawas sitting outside the Cantina. They're initially sitting in a shadow, but when Luke and Obi-Wan walk towards them, they're suddenly in broad daylight.

Revealing: In the shot where Han Solo and Luke jump down the garbage chute, Smoke outlines the end of the corridor, revealing it is a board with the scenery on it.
