Corrected entry: When the four heroes are in the garbage compactor and Luke gets sucked under by the water creature there is only a foot to a foot and a half of water in there. Luke should have at least been able to stick his arm up for Han to grab. Even if he didn't Han should have been able to find Luke a lot quicker than he did.
Corrected entry: In the scene of Mos Eisley, where we see a Jawa fall of the creature, look at the right corner of the screen and you will be able to see a silver car standing there. It's a Volkswagen.
Corrected entry: When the Rebel star fighters are approaching the Death Star, there are a handful of X-Wing fighters and three Y-Wing fighters. During roll call, three members of Gold (Y-Wing) Squadron report in. In the ensuing battle three Y-Wings are shown exploding and three Y-Wing pilots are shown dying. When the Death Star explodes, shown escaping the explosion are the Millennium falcon, two X-Wings (Luke and Wedge), and one Y-Wing. Interestingly, Lucas upheld his "new math" when he remade the approach run digitally for the Special Edition.
Corrected entry: R2-D2 has several small, blue colored sectors on his dome shaped head. But in shots of him riding an X-wing against a star-filled background the sectors are black. In those scenes the robot was filmed against a blue screen, and the blue areas had to be changed for SFX purposes.
Corrected entry: When C3-PO is getting into the oil bath inside the garage and is talking to Luke, as Anthony Daniels had restricted vision from wearing C3-PO's helmet, you can see Luke walk across the room, and C3-PO doesn't see this and continues talking in the opposite direction to where Luke is.
Corrected entry: When the stormtroopers enter the docking port where the Millenium Falcon is, they start firing. Despite the fact that there are 5 or 6 of them, not only can't they hit Han but there is no damage whatsoever to the Millenium Falcon. But Han, who only has a single gun, manages to destroy half the port.Gavin Jackson
Corrected entry: The blueprints of the Death-Star that are retrieved from R2-D2 and shown to the group of rebel pilots are wildly inaccurate as far as representing what the Death-Star actually looks like. The big circular 'laser generating' ring that is shown to be located directly upon the equatorial 'trench' in the blueprints, is in the very next scene of the 'actual' Death-Star to be shown residing in the northern hemisphere of the Death-Star, about midway between the trench and the 'north pole'.
Corrected entry: When all the X-wing pilots are shown on the ground getting into their X-wings and strapping in, all the canopy windows are very dark-tinted, as are the visors on their helmets. However, once in flight, the windows are totally clear, and the visors are a very light orange tint.
Corrected entry: When Artoo and Threepio are in the escape pod early in the film, a shot shows them 'talking' while looking out a round port-hole at the receding imperial star destroyer that they just escaped from. The angle implies that the port hole is on the section of the pod that is facing the destroyer. In the very next shot, the outside section of the pod facing the destroyer is seen, yet there is no window or port hole that the two 'droids could have been looking out of. In fact, the bottom of the pod is completely filled up with rocket engine gimbals.
Corrected entry: Immediately after escaping the 'Death Star', Han and Luke climb into the Millennium Falcon's gun-turrets to mount a defense against the four attacking TIE-fighters. Han climbs up the ladder to the upper turret, while Luke climbs down to the lower one. However, whenever one of them scores a 'hit' by destroying one of the TIE-fighters, the editing makes them appear to be at the opposite ends of the tunnel: One of the TIE-fighters that Han destroys sweeps across the bottom of the ship before he shoots it, and the big dish antenna on the top of the Millennium Falcon can be seen as the TIE-fighter that Luke destroys flies by.
