During the Opera scene Palpatine tells Anakin about the dark ways of the force which he listens to without question. However later in the movie when they next meet Anakin asks him, "How do you know about the force?" as if he didn't know that Palpatine already knew about it. Anakin even acts as if he didn't know that Palpatine knew about the force. [In the Opera scene, Palpatine is telling Anakin a story relating to the Force that, as far as the younger man knows, he could have picked up anywhere - Anakin has no doubt heard a number of such tales in his time. In their later confrontation, it becomes clear that Palpatine knows how to USE the Force, which is something else entirely - when he questions Palpatine, Anakin is asking him where he gained this ability.]

Throughout the Mace Windu VS Palpatine fight you can see in most action shots the face of Palpatine is not Ian McDiarmid, but a stunt double. [According to the "Making Of" book and the Episode III set diary at starwars.com, Ian McDiamird did all of his stunts, except for the ones that are CGI (like the jump at the beginning of the fight). Although he did *have* a stuntman, he never did anything during the fight.]

During the fight between Anakin and Count Dooku, there's at least one shot where a lightsaber's shadow is visible on the floor. You see a shadow because they use a stick during the filming and later add the special effect. [Throughout the series of films, there are numerous shots where a lightsabre blade is seen to cast a shadow. As we don't know anything about the energy used to create the blade, we cannot say that it shouldn't cast a shadow, not least at the blades aren't translucent, meaning they definitely block light in some way.]

When Obi-Wan and Yoda are watching the video of Anakin becoming Darth Vader, and killing younglings in the Jedi temple, Obi-Wan refers to Palpatine as the Emperor - but he would not have known that Palpatine had declared himself Emperor. [In that video, Palpatine refers to the Republic as "The Empire." If it's an Empire, it has an Emperor. Obi Wan came to the logical conclusion that Palpatine had declared himself Emperor.]

When General Grevious's ship begins to de-orbit and crash, it turns its bow towards the planet's surface. The next shot of the characters inside the ship has them all tumbling towards the bow. This is wrong. Since they are accelerating towards the planet, the force they feel should pull them to the stern of the ship (much like accelerating in a car, the force pushes you back into your seat, opposite the direction of your acceleration). They should have been "falling uphill" in that shot. [While this may be true for a car accelerating on the ground, it does not apply in this case. The ship is "falling out" of the sky. It is accelerating under the force of gravity. Laws of physics state that all objects fall at the same rate under gravitation (g) force regardless of weight and size. However, as the ship is being slowed down by atmospheric friction but the people inside are not, their strugle to move "upwards" is true.]

Obi-Wan & Anakin manage to pilot what's left of General Grievous' star destroyer to a survivable landing on Coruscant. As they do, the ship is steered towards a long, straight landing strip in the city. Since when do spaceships & aircraft in the Star Wars universe need landing strips? Everything, including even the largest ships, use advanced hovering technology, and can make pinpoint vertical take offs & landings. [A couple of explanations for this arise: 1. There is no guarantee that every civilization has the hovering technology, or that they are willing to use it. The landing platforms must be able to accomodate all kinds of craft, even if there appears some without hovering capability. 2. Technology is developed over time, and the landing strips might just as easily be a leftover from the days when few ships had the VTOL technology. And furthermore, not every ship has the capability to land. "The largest ships" that you mention does not have this, as they are built and operate entirely in space. It would be very impractical to attempt to land a Super Star Destroyer (seen in "Return of the Jedi") or a Nebula-B frigate (the hospital ship from "Empire Strikes Back") on a planet surface.]

A physics-related mistake in the scene in which Obi-Wan and Anakin attack Gen. Grevious's ship: As they approach the hangar bay in their fighters, Anakin shoots out the forcefield generator, rendering the hangar bay completely exposed to the vacuum of space. The Jedi crash-land their craft in the hangar just before the emergency doors close on them and then they instantly leap from their respective cockpits to engage the guard-droids. There is no conceivable way to replenish that huge volume of air in the few seconds elapsed between the hangar doors closing and the Jedi exiting their ships. Even if the air (and heat) could be replenished that quickly, the massive pressure difference it caused would've produced a shock wave, and likely ruptured their ear drums. [Their technology is a bit more advanced than ours: The interstellar travel, hyperdrive, robotics, lightsabres, cloning, etc. They should be able to find someway to repressureize the hangar quickly and safely.]

As Anakin cuts off Dooku's head, you can see Dooku's head fly straight backward at high speed. However, in the next shot where Dooku's body tumbles over, you can see the head rolling in the wrong place and very slowly. [The cut-off head is barely visible in the lower right corner of the screen. It's almost impossible to say into which direction or how fast it flies away.]

In the scene where Obi-Wan's leaving on his mission to search for the separatists and saying goodbye to Anakin, the ship he's boarding isn't there until he makes the final turn to leave, and suddenly its docked there with ramp down for him to board. [The huge star destroyer is always there in the background - although quite far away.]

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. [Padmé does not come from Earth. Maybe babies on Naboo are bigger and don't have an umbilical cord.]

Near the start, as Anakin and the politicians start walking away, Jar-Jar says "excuse me" to a large blue creature next to him. In the next, wider shot, there's now another creature between them. [There is no creature between Jar-Jar and the large blue creature. In the tight shot Jar-Jar and the blue creature are standing side by side. As they start to walk, Jar-Jar walks slower than the blue creature so in the wide shot he’s slightly behind it, but at no point is there a creature between them.]

The cartoon Clone Wars was the only record of General Grievous besides Stars Wars III. In the cartoon, he put his lightsabers around his waist allowing him to kill two Jedi at once, not in his cape, in the movie. Grievous probably would've killed Obi-Wan since he would also have 2 more lightsabers. [Yes true but the films are the only source considered "Canon". It's a moot point anyway whether or not Grevious had spare Lightsabers, he wouldn't have been able to use them after losing two of his four hands against Obi-Wan.]

Chewbacca is good friends with Yoda in Episode 3, but joins in with Han Solo in making fun of Obi Wan in Episode 4: " You said it Chewy. Kid, where did you dig up that fossil?" If he was such good friends with the leader of the Jedi Council, why would he later make fun of one of the last remaining Jedi? Maybe he never met Obi Wan but you'd think he would be thrilled to meet anyone who claimed to know the ways of the Jedi. After all, Obi Wan was instructing Luke on the ways of the force right in front of him on board the Millennium Falcon. [As the Wookies were enslaved by the Empire for the crime of assisting the Jedi, it's quite reasonable that Chewbacca would be somewhat less in awe of them these days.]

I realize this and all the Star Wars films are family-oriented, but after Anakin has hacked the 'younglings' to death with his lightsaber, all the little bodies appear to have no sign of injuries or trauma, not even any blood is spilled. It's as if they're just taking a nap. [Lightsabres are so hot they seal wounds shut, so there would be no blood.]

The "ignition" sound for specific lightsabers in this movie, as with the other two prequels, rarely matches up from one fight to the next. For example, when Anakin is a "good guy", his lightsaber sounds just like Obi-Wan's when it starts up. But when he goes in to kill the Younglings, it sounds like Darth Vader's in the original trilogy. [They do this as foreshadowing since Anakin has now turned to the Dark Side.]

In the 3 Tantive IV (Senator Organa's ship) hallway scenes, small details in each scene show that they are all the same hallway (red symbol above door, arrangement of metal plates on both sides of door, location of black squares on side walls, location of side doors). The same exact small details can all be found in the hallways Darth Vader makes an entrance into in A New Hope, meaning this is supposed to be the same hallway (that's also been confirmed by official sources - they went to great length to recreate the ship exactly, based on photos of the original set). However, the hallway in ROTS is much narrower. [A good observation, but remember that the events of Episode IV take place after Luke has grown to be a young man. Since the halls in the 3 Tantive IV ship are still pure white in Episode IV, it's plausible that renovations could have been made to the ship during the years Luke was growing up.]

In the scene where Plo Koon is killed (the Jedi that dies while piloting an old Jedi starfighter), one shot shows him in his cockpit before it explodes from clone fire. The cockpit window shows that there are three separate window panels, much like the design in the fighters Anakin and Obi-wan fly in the beginning of the movie. The old Jedi Star fighter only has one full window panel. [Clearly this isn't quite the same as the earlier design - unless we actually see that what he's flying only has the one panel at some point, this can't be considered a mistake.]

In the Mace Windu/Palpatine fight scene, the glass window is shattered after being hit by a lightsaber and heavy wind is blowing into the room where there are fighting. However, while Palpatine is talking to Anakin after the fight, there is no more wind in the room. [The wind was caused by the air pressure changing in the room, much like an airplane that has a sudden hole blown into it. Once the air pressure balenced out, the wind ceased to blow in the room.]

Following the battle on the bridge of the starship Obi-Wan and Anakin infiltrated in the beginning of the movie, the windows are shattered and protective shutters move down. In a following scene showing the bridge from the outside, the bridge is shown to still have windows. [The shutters only cover those windows that are damaged - the others remain clear.]

When Anakin is leading the troopers into the Jedi Temple, the sound of footsteps doesn't match the actual march from the clone soldiers. [The "marching" sound heard as Anakin approaches the Jedi Temple with the troopers is actually part of the score - not a sound effect.]
