Corrected entry: When Anakin is leading the troopers into the Jedi Temple, the sound of footsteps doesn't match the actual march from the clone soldiers.
Corrected entry: Early on in the film we see General Grievous escape from the Jedi by leaving a ship and skipping around in space. It is later established that the General has some internal organs (heart and maybe lungs) when Obi Wan kills him. How did these internal organs survive the vacuum of space, not to mention the cold and radiation?
Correction: According to Star Wars Revenge of the Sith: The Visual Dictionary, General Grievous's "gut sack is pressurized synthskin, allowing Grievous to survive in a vacuum." I assume this futuristic synthskin also protects his internal organs from the cold and radiation.
Corrected entry: After Palpatine has been rescued the ship starts to sink directly downwards. However there is a cut to Grievous at the front of the ship and everything is upright.
Correction: The point of view of this shot is directly facing Grievous, an image that would look the same no matter what angle the ship is at. [Note: Though not a part of the film, the book clarifies that Grievous's outer coverings are magnetic, which would cling to the floor of the vessel when it is magnetized.]
Corrected entry: Padme gives birth to two full size babies, but looking at her stomach, she's barely carrying one full size baby.
Correction: All women carry babies at different heights, and their stomachs appear to be different sizes.
Corrected entry: When Anakin cuts off both of Dooku's hands, Dooku's hands are at waist level. Yet after the cut, Dooku's lightsaber is now flying above head level for some unexplained reason.
Correction: Anakin either flipped it up in the air by directing his final slice upward, or he used the Force to do it so he could easily retrieve the saber.
Corrected entry: During Obi-Wan's departure scene on Coruscant, when he is telling Anakin how proud he is of him, Obi-Wan's eye color shifts from Ewan McGregor's' natural blue-green eyes to a dark brown.
Correction: There's no mistake or modification. The shift in Obi-Wan's eye color is due to a shift in shadowing and lighting,.
Corrected entry: On the bridge of Grievous' ship, Obi-wan cuts the head off of a magna droid and it keeps fighting. However, right before Obi-wan faces off with Grievous on Utapau, he cuts off the head of a magna droid and it falls dead.
Correction: The magna droid on Utapau is already badly damaged, so the loss of the head is enough to finish it off - in the prior encounter, the magna droid is otherwise in perfect shape, so is able to continue fighting.
Corrected entry: As Anakin tries to land General Grievous' ship on Coruscant, they are escorted by ships that try to put out the fire on Grievous' ship by shooting liquid on the flames. Given the intense speed at which they are traveling, the liquid should immediately fly backwards in a mist rather than stay mostly in a stream as it leaves the escort ships. (Try throwing water out a car window at 60mph to understand).
Correction: If the pressure is high enough, the stream could maintain cohesiveness for the short distance to reach the ship. Also, since it some sort of fluid that is clearly heavier than water (as it foams up and sticks to the hull of the ship), that would help keep it together as well.
Corrected entry: When Palpatine and Mace Windu are fighting and Palpatine is taking damage. His mouth is gaping in pain and you can get a clear view of his teeth - the number, cleanliness and configuration change between shots.
Correction: Well, yes Palpatine's teeth are changing drastically between shots. They are quickly deteriorating, as is his face, as a result of the powerful reversal of his force lightening.
Corrected entry: After the crash landing on Coruscant, Anakin, Kenobi, and Palpatine take a shuttle to the Jedi Temple. While Anakin and Kenobi are talking by the shuttle entrance a droid behind them picks up a single piece of luggage. After a few more moments of dialogue the same droid picks up the same single piece of luggage.
Correction: This is incorrect. In the first shot of the luggage there are three items - two on the right and one on the left. The robot removes the top right item, the view flicks to Obi-Wan and then back to the luggage and Anakin, but the angle is different so the second item looks like it's in the first's position. However, the third left hand item proves its position as the lower item of luggage.
Also, the shuttle doesn't take them to The Jedi Temple, it takes them to The Senate Office Building.
Corrected entry: Anakin has his lightsaber in his hands immediately after having his handcuffs cut off on the bridge of General Grievous' ship. In the next shot, he has to force-retrieve it from Grievous.
Corrected entry: In the opening battle General Grievous shatters the front glass on the bridge to escape. A metal barrier slides into place to stop the bridge from decompressing. But when Anakin is trying to land the disabled ship the metal barrier is gone and the glass appears to be back in place. If the metal barrier had just withdrawn everyone on the bridge would be being buffeted around to an insane degree by inrushing wind.
Correction: The metal shield only covered the damaged sections to the side (you can see it stop as it moves accross). On the closeup as the ship lands we can see only the very front of the bridge has intact glass, the rest of the bridge has metal shielding over the broken windows.
Corrected entry: When Padmé just has landed on the volcanic planet and is about to get off the ship, she is wearing a green/grey costume and no trousers. When she arrives at the platform she wears the same costume but also a grey pair of trousers.
Correction: Padme is always wearing trousers. They are fitted and so are not always easy to see as separate from skin.
Corrected entry: After Obi-Wan gets off that rainbow coloured creature he was riding, he reaches to pet him. His hand actually never touches the creature.
Correction: Obi-wan is pretty absorbed in looking at General Grevious and all of the droids. I would imagine his mind is not really on consoling the creature; therefore, him missing a "pet" is his mistake as a human, and not a mistake in the movie.
Corrected entry: When Mace Windu and Palpatine are fighting, Mace knocks Palpatine's lightsaber out of his hand and it goes flying out the window where the glass used to be. However, Palpatine has it later when he fights Yoda.
Corrected entry: In the opening scene where Anakin and Obi-Wan are flying to General Grievous's ship, a clone commander says, "All fighters follow me in." When he says that, his mouth doesn't move.
Correction: No such line is uttered in the opening battle. The only lines uttered by clone pilots, where you actually see the clone, are: "We're on your tail, General Kenobi.", "Set S-foils in attack position.", and "They're all over me. Get them off my-". All of them have corresponding lip movement.
Corrected entry: When Aayla Secura, the blue-skinned female Jedi, is killed, in the first shot, she's holding her lightsabre in her right hand (look closely in the lower left hand corner). In the next shot, the sabre is clipped to her belt, but in the following shot, she's holding it again. (01:18:30)
Correction: Aayla Secura carries 2 sabers.
Corrected entry: When Anakin and Obi-Wan are fighting on the table in the control centre, you can see the faces of the stunt doubles in some shots. For example, in the shot before Obi-Wan kicks Anakin for the second time, the face of Hayden Christensen's stuntman is obvious.
Correction: There were no stuntmen used for this duel, all the fighting was done by Hayden and Ewan. They only used digital images for the superhuman jumping, but no stuntmen.
Corrected entry: When the babies are born they are too big to be newborns. They appear to be 9-11 months old. Also there are no umbilical cords when they are born.
Correction: Padmé does not come from Earth. Maybe babies on Naboo are bigger and don't have an umbilical cord.
Correction: The "marching" sound heard as Anakin approaches the Jedi Temple with the troopers is actually part of the score - not a sound effect.
