Corrected entry: Toward the end of the movie, there are plans for a weapon that the "republic must not know we are building". It looks like the Death Star from Episode 4. However, according to many sources, the Death Star was made under the rule of the Empire. Palpatine personally oversaw its design, which was made by the same man that later designed 2 other super-weapons. How can it be that such a weapon is thought about when the person that designed the planet destroying super-laser, and the housing for it (The Death-Star itself) isn't even a teenager yet?
Corrected entry: When Anakin visits Cliegg Lars on Tatooine, it has only been 10 years since he left his mother. Ten years is not long enought for her to have been sold by Watto, marry Lars and have a fully grown child.
Correction: Common misconception - Owen is Anakin's step brother, not half brother. He's Cliegg's son (presumably from an earlier marriage), not Cliegg and Shmi's son.
Corrected entry: When Boba Fett picks up his dad's helmet (presumably with head still inside) it is remarkably lightweight.
Correction: Jango Fett's head flew free of his shoulders and fell out of his helmet - you can see two separate shadows if you look closely.
Corrected entry: In the final battle, Mace Windu has climbed aboard Yoda's open ship and turns around to deflect the blaster shots with his lightsaber. However, one of the shots slips through and would have hit him right in the chest. About 10 centimeters from his body, the red shot mysteriously vanishes... Obviously an interaction between live character and CGI that went wrong. (01:57:10)
Correction: The only one he doesn't block is closer to the camera than him - we see it impact on the side of the ship.
Corrected entry: Amidala is slashed across the back in the arena by one of the creatures. Later, when she falls out of the ship and onto the sand, the slashes have disappeared.
Correction: Not true - they're narrow slashes, and given that her top moves up and down a bit they're sometimes covered, sometimes not.
Corrected entry: During the fight between Anakin and Dooku, Anakin cuts that cable and all lights go out (all lightspots on the ground disappear). When Padme and the troopers arrive, the lights are up again, and lightspots can be seen again on the floor.
Correction: The cable was connected to the ship, not the lights. However, the slash would have caused a power surge back through the system that caused the lights to temporarily dim. They came back on right away during the battle.
Corrected entry: In Empire Strikes Back, Yoda tells Luke that he trained Obi-Wan. In Episode I Qui-gon had trained Obi-Wan.
Correction: This is explained on the Star Wars website (the databank makes fascinating reading if you're so inclined), but we also see the evidence. Yoda trains children up to a certain age, then they are partnered with a more senior Jedi for their apprenticeship.
It's actually Obi-Wan that says it. "Luke, you will go to the Dagobah System. There you will learn from Yoda, the Jedi Master who instructed me." Yoda not only trained Obi-Wan as a Padawan, but also well into Masterhood. At the end of Revenge of the Sith, "In your solitude on Tatooine, training I have for you" where he trains Obi-Wan how to commune with Qui-Gon.
Corrected entry: So, a clone army is being developed, supposedly for the Republic. The template they are using for the cloning is Jango Fett, who is an ally to Count Dooku. Yet, when the Clone Army of the Republic goes to Genoisis and they are fighting Dooku, he's wondering how the Jedi managed to come up with such an army so quickly...
Correction: Dooku knew about the army all along. He was pretending so his "gang members" wouldn't think he was turning on them because he hadn't used them to fulifll their purpose yet. He and the soon to be Emporer had it all worked out as stated in the end "Everything is going as planned."
Corrected entry: During the conversation with supreme chancellor Palpatine at the very begining of the film, he states that he will not let this Republic which has stood for a thousand YEARS be split in two. This is an error as the Republic has stood for a thousand GENERATIONS (as stated by Obi-wan in episode 4).
Correction: Actually, in Episode IV Obi-Wan says "For a thousand generations the Jedi Knights were the guardians of peace and justice IN THE OLD REPUBLIC." So the Republic has stood for a thousand generations. However, it is quite possible that Palptine intentionally misspoke, and for two reasons. First, he wants to appear less than competent, as indicated in the Attack of the Clones novel. Appearing ignorant of history makes him look like a foolish politician who is no threat to anyone. The Jedi would not fear him having emergency powers because he appears to be not that bright and they can control him. Secondly, the Sith where wiped out a thousand years ago. To him, the Republic has been a mortal enemy for a thousand years, so that's the number he's fixated on. He is revealing himself to the Jedi as the Sith Lord, and they are too arrogant to realize it..
Corrected entry: In the scene when Obi-Wan is being held in captivity on Geonosis and is speaking with Dooku, watch Dooku as he circles Obi-Wan while he talks. At one point after a shot of Obi-Wan, a shot of Dooku has his hands clasped across his midsection, but also notice he is amazingly holding the sides of his cloak. Four hands Dooku? You are on the dark side aren't you?
Correction: At times Dooku has his right arm lying across his stomach, but while he is doing that, his left hand is at his side. Then after a short while he drops his right arm to his side as well. He never clasps both hands across his middle.
Corrected entry: When Obi-wan sees Count Dooku on his speeder, and Anakin says "shoot it down," the clone responds that they're out of missiles. What about the fact that the assualt ships are bristling with lasers?
Correction: Count Dooku obviously knows about the clone army, and the clones are probably under instructions not to take out Dooku, so they use the excuse of having no missiles.
Corrected entry: In the scene where Anakin is in Padme's bedroom and he is whining about Obi Wan, he is floating a ball with the force. The ball's reflection shows in the window, but you cant see Anakin's reflection at all.
Correction: The ball's reflection shows more obviously because it is closer to the window where it was originally placed. As Anakin pulls it to his hand, you can see his hand reflected in the window as well, very faintly. The rest of his body does not show a reflection because he is too far away from the window.
Corrected entry: In the scene where the transport carrying Obi-Wan, Anakin, Amidala and the clone troopers is chasing Dooku, the pilot mentions that the ship is out of missiles. In a close-up shot of Anakin, a pod full of missiles can be seen on the wing of the transport in the background.
Correction: He uses that as an excuse. (As he is more than likely 'programmed' not to kill Dooku).
Correction: The only absolute rock hard definite sources are the films - George Lucas has publicy stated that. The books are by and large right, but the films take priority if ever there's a conflict. Therefore what we see in the films is "fact", so to speak, and the books are fiction, regardless of the order they were produced.
