Continuity mistake: Before the lightsabre duel begins, Anakin says, "You're gonna pay for all the Jedi that you killed today, Dooku", and Obi-Wan's lightsabre is pointing downwards at the end of the shot. But in the next shot, it's pointing upwards. Anakin is holding his lightsabre closer to his leg as well. (01:59:55)
Continuity mistake: After Obi-Wan sneaks into the corridor in the stalagmite-like tower on Geonosis, he stops and looks up. In the next shot of him, he is still standing and looking up, but the wall behind him is different from the previous shot. (01:12:40)
Continuity mistake: At the beginning of the scene where Anakin and Amidala are getting off the transport, they start to talk. The conversation goes on for a short time, and then the scene cuts to an angle where we can see the transport again. It is far to much away for the time they walked and talked.

Continuity mistake: After Obi-Wan and Anakin enter the nightclub, they stop, and as the shot ends, Anakin head is turned to his right, and Obi-Wan is turned slightly towards Anakin. In the next shot, Anakin's head is turned to his left, and Obi-Wan and Anakin are both turned in the same direction. (00:21:20)
Continuity mistake: In the fight with Dooku and Yoda near the end, there is a far shot and Yoda is behind Dooku, but Dooku is still fighting in front of him. Also it still makes the sound of lightsabres clashing.
Continuity mistake: On Tatooine when Anakin first gets on to the swoop bike, two legs which the bike is standing (hovering) on is visible. This is even so while he is racing along tatooine landscape. These legs are no longer visible when he returns with Shmi. (01:23:10)
Continuity mistake: During the meadow picnic, some of Amidala's hair is lying over her right shoulder, but in the long wide shot, it's not. (00:46:05)
Continuity mistake: In the wedding scene, there's a close-up of C-3PO and R2-D2. If you watch the background behind them, you can see that it is the same background seen in the shots of Anakin and Padmé, only reversed. This can be seen from the tree, the flowerpots and the mountain. (02:09:50)
Audio problem: When Anakin is talking to Padmé by the fireplace, he says,"My heart is beating, hoping that that kiss will not become a scar", and stops talking, but his profile shows that his lips are still moving. (00:52:30)
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: When Anakin and Padmé share their first kiss as husband and wife, in the first shot, they are standing in front of two trees and a bunch of roses. But in the rest of the wedding scene, there are no trees or roses behind the couple. (02:09:45)
Continuity mistake: When Obi-Wan is head butted by Jango Fett during their fight, in the shot where he falls, Jango's costume is reversed. The easiest way to see this is to watch the antenna on his helmet, which is on the wrong side. (00:59:15)
Other mistake: When the star ships are about to pass through the clouds over Coruscant in the beginning of the film, the shadow of the large Naboo Cruiser can be seen far ahead of the ships, but the smaller star fighters have no shadow. And when the ships fly closer to the clouds, the shadow of the cruiser disappears as well. (00:02:20)
Continuity mistake: In the arena, Anakin rides up to the pillar that Padmé is on top of, and when he tells her to jump, the pillar is on his right. When Padmé lands behind Anakin a few seconds later, the pillar is to their left. (01:44:35)
Other mistake: When Anakin is searching for his mother, in the shot where we see the binary sunset, neither Anakin nor the speeder he's riding has a shadow. (01:11:55)
Continuity mistake: There are at least 12 random bodies strewn about the arena during the Jedi/droid battle that are neither Jedis or droid. A couple are actually wearing regular shirts.
Continuity mistake: When Jango Fett and Obi-wan Kenobi are fighting on Kamino, Obi-wan's lightsaber gets blasted out of his hands and it lands near the edge of the platform, but when we see it again it's nowhere near the edge of the platform.
Continuity mistake: During the last shots of Obi-Wan and Anakin's conversation at the nightclub, the surroundings and the amount of people around them keeps changing. (00:21:40)
Continuity mistake: When Anakin and Padmé walk towards the moisture farm, in the first shot, their shadows are on their right. In the next shot, their shadows are cast behind them. In the following shot, the shadows are on their right again. The shadows on the ground differ as well, their size and intensity changes between shots several times. (01:08:25)
