Continuity mistake: When Mace Windu walks out on the arena balcony, Count Dooku says, "How pleasant of you to join us" and Mace is standing on the left side of the balcony "door". In the next shot, he is standing on the right side of the door. (01:45:40)
Continuity mistake: Watch Mace Windu's lightsaber when he is deflecting shots from the Super battle droids on the balcony of the arena. The blade, which is supposed to be purple, has switched colour to blue. (01:46:10)
Continuity mistake: When Anakin and Padmé are talking to one another in the field, Anakin says, "Well, then they should be made to." In this shot, there's a ribbon in Padmé's hair that can't be seen during the rest of the conversation, even though it should be visible, because of its position. (01:46:55)
Other mistake: How is it that one slash on Amidala's back ripped off the entire midriff of her shirt, and a sleeve? (01:47:00)
Continuity mistake: When Padmé gets her back scratched by the nexu, she seems to bleed. Even though she is wearing all white, and the scratches seems to be deep, her white top remains squeaky clean during the rest of the movie and does not get dirty from her wound. The wound itself also vanishes, not reappearing for the rest of the Geonosis sequence, even when she falls out of a gunship and goes rolling in the sand. (01:47:35)
Continuity mistake: The Nimoidian mouths are inconsistent with The Phantom Menace. The mouths of Nimoidians (Nute Gunray and his assistant) work inconsistently to how they did in Episode 1. In this film the centre of the mouth moves outwards rather than the edges moving out. (01:47:35)
Continuity mistake: When Mace is fighting Jango in the arena, the bull charges, then again, when Jango shoots him he then turns around to face Mace. The continuity from right to left is switched, he should not have had to turn around. (01:48:25)
Continuity mistake: In the close-up of Mace Windu after he beheads Jango Fett, his under tunic is reversed. It is overlaying to his left instead of his right. (01:48:45)
Continuity mistake: During the battle in the arena, Anakin and Padme falls to the ground as the cart is knocked over. Padme lands right in front of the cart, but in the next shot, she is further away from it. (01:49:20)
Revealing mistake: After R2-D2 begins to drag C-3PO's head across the arena, there's a shot of several Jedi fighting. A man wearing a dark brown tunic falls over dead, but if you watch closely, you can see that he was never actually hit by any laserbolt. (01:50:15)
Continuity mistake: After Padme shoots the Geonosians off the chariot, we see a shot of Anakin slicing down come droids. When he turns his body around to face the camera, we can see that he is using the incorrect lightsaber hilt, instead using what looks to be the one that is broken in the factory earlier in the film, judging by the black grips on it. (01:51:30)
Suggested correction: The lightsaber he is using was given to him by other Jedi, they threw one each to him and Ben so I doubt very much it is that particular lightsaber from earlier.
Continuity mistake: After the Jedi have escaped the arena and Yoda tells what will happen if Dooku escapes, Mace Windu's under tunic is overlaying to his left, but in the arena, it was overlaying to his right. Later in the scene, it is back to the way it should be. (01:53:00)
Continuity mistake: In the fight scene in the arena, after the moving vehicle that Padme and Ani are on gets shot down, she gets into the carriage seat for cover. In the first shot, her hair is hanging down and wispy on the right side. In the next shot, it's nice and combed up. (01:54:00)
Continuity mistake: In the scene on Geonosis where the droids are closing in on the remaining Jedi, the camera keeps cutting close and cutting back out. In only two of these changes is a blue Twilek (Aliens with tentacles on their heads like Bib Fortuna) visible. She has disappeared in the other camera angles. (01:56:00)
Continuity mistake: During the battle of Geonosis, Ki-Adi-Mundi has a blue lightsaber. After the clone army arrives, there is a shot of Obi-Wan and Mace, then Anakin, then Padme. During that shot of Padme, over her right shoulder, Ki-Adi can be seen with a green lightsaber. It then changes back to blue when he is on the transport ship deflecting laser shots. (01:56:50)
Audio problem: When Padmé falls from the ship, she screams, but her lips stay closed. (01:58:30)
Continuity mistake: Before the lightsaber duel begins, Anakin says, "You're gonna pay for all the Jedi that you killed today, Dooku", and Obi-Wan's lightsaber is pointing downwards at the end of the shot. But in the next shot, it's pointing upwards. Anakin is holding his lightsaber closer to his leg as well. (01:59:55)
Continuity mistake: When Obi-Wan and Count Dooku are duelling, the background behind them is inconsistent between shots. They are closer to the walls in the close-ups than in the wide shots, and sometimes the background itself changes between shots. For example, when Dooku says, "Master Kenobi, you disappoint me", there's a wall behind him, but in the previous shot, the opening of the hangar could be seen behind him. (02:00:25)
Continuity mistake: When Anakin is fighting Count Dooku, he takes Ben's blue light sabre in his left hand, in the next shot he is holding it in his right hand. (02:01:10)
Continuity mistake: When Obi-Wan and Count Dooku are duelling, in the second shot after Padmé and the clone trooper run away, the positions of their lightsaber is different from the first shot. Dooku's lightsaber is on the other side of Obi-Wan's, and strikes it higher up. (02:01:10)
