Continuity mistake: When Anakin and Padmé are talking at night at the lake retreat, the flames in the fireplace are inconsistent between shots. (00:51:35)
Continuity mistake: After Padmé falls down onto the conveyor belt, Anakin jumps down after her, and right before he lands, there's a clear shot of the conveyor belt moving the same way Padmé went. Judging from the speed of the conveyor belt and the fact that she was only a few seconds ahead of Anakin, Padmé should be visible, but she's nowhere to be seen. (01:34:00)
Continuity mistake: In the bar scene on Coruscant, when Anakin is tracking Zam Wessel through the bar, his Jedi braid changes sides - it is on the left side of his head in a shot where he is seen from behind. At all other times in the movie, the braid is on the right side of his head. (00:22:40)
Continuity mistake: When Obi-Wan and Anakin enter the nightclub, in the first shot, there are people in front of and behind them. In the next shot, some of them have disappeared, some have changed position, and there are some people that were not there in the previous shot. Then during the last shots of their conversation, the surroundings and the amount of people around them changes a few times. (00:21:10)
Continuity mistake: When Anakin is talking to Watto, the positions and existence of some of the objects surrounding Watto keeps changing between shots.
Continuity mistake: When Anakin and Padme are going into the droid factory on Geonosis, watch the last Geonosion warrior Anakin kills before going through the door into the actual droid factory. Anakin's lightsaber goes straight through the shoulder of the warrior, but nothing happens. Then Anakin proceeds to kill it using a force push and then slicing it in half. (01:37:45)
Continuity mistake: During the arena battle on Geonosis, Jango Fett flies in to go after Mace Windu. When he lands, he holds nothing in his hand, but as the Reek detects him, he has his blaster pistol in the left hand. The Reek stampedes him, and there Fett is missing his pistol, but when the beast turns around and charges again, Fett suddenly holds the pistol in his right hand.
Continuity mistake: On Tatooine, after Anakin's mother died, and they laid her to rest, you notice the shadows of the tombstone's are all facing one direction. When R2-D2 comes over, you'll notice that his shadow is going in a different direction. Can't be explained by the two suns, as we've seen many times that they don't produce two distinct shadows. (01:27:45)
Continuity mistake: During Obi-Wan's tour at the clone facility, as Lama Su explains that they modify the genetic structure of the clones, he is walking in front of Obi-Wan. As the next shot begins, he is walking behind him. Then, when he mentions the unaltered clone, he and Obi-Wan are walking side by side, but in the next shot, he is once again in front of him. (00:44:50)
Continuity mistake: When Padmé is trapped in one of the vats that get filled with molten metal, the vat two spaces ahead of her is filled up twice: once after Anakin's arm gets stuck, and once as the flying R2-D2 comes to save her. Then, as R2 lands, Padmé's vat moves one step closer to the metal-pouring mechanism, and the vat next to her is just about to get filled up. But about ten seconds later there's an overhead shot, and molten metal is being poured into the vat next to Padmé's, even though the vat, and Padmé's vat as well, should already have been filled up by the time given. (01:36:55)
Continuity mistake: When Anakin is crying on Tattooine, he starts to cry and the tears are running down his face, but then they disappear and his face is completely dry, then there are more tears, and the same thing happens again.
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)
