Audio problem: When Obi-Wan and Darth Maul are fighting, after the second time Maul swing his lightsaber over Obi-Wan's head, their lightsabers make contact three times, but there are four clashing sounds. (01:56:35)
Continuity mistake: When the final duel between Obi-Wan and Darth Maul begins, they are fighting in a particular area next to the pit. But when Obi-Wan cuts Maul's lightsaber in half, the background changes and they are suddenly fighting on a different side of the pit. (01:56:40)
Deliberate mistake: When Obi-Wan is fighting Darth Maul alone, after Obi-Wan cuts Maul's lightsaber in half, they start fighting on a different side of the pit. But after Maul kicks him, a close-up of Obi-Wan shows the wall and smoke of the area that they left. The shot has been reversed as well. The easiest way to see this is to watch his braid, which is on the wrong side. (01:56:55)
Audio problem: Before the Trade Federation Droid Control Ship starts exploding from the inside, a Neimoidian says, "Nothing can get through our shield". But his mouth doesn't move until after he's said it. (01:57:45)
Revealing mistake: When Darth Maul is harassing Obi-Wan as he dangles in the pit, the first swing of Darth Maul's sabre is out of sync with the resultant sparks (very evident in slo-mo). (01:58:50)
Continuity mistake: At the end, after Darth Maul has knocked Obi-Wan into the pit, Obi-Wan is beginning to remember about Qui-Gon's lightsaber. The scene shows Darth Maul with the lightsaber in his right hand. When Obi-Wan leaps out of the pit and flies over Darth Maul, the lightsaber switches to Maul's left hand. (01:58:55)
Continuity mistake: When Obi-Wan kills Darth Maul, he grabs Qui-Gon's lightsaber with his left hand. But when he twists above Maul's head, he's holding it in his right hand. In the next shot, it's back in his left hand. (01:59:10)
Continuity mistake: When Darth Maul is killed and begins to fall, he is holding his lightsaber, but when we see him falling down the pit, no lightsaber is falling through the air. (01:59:15)
Other mistake: After Darth Maul is killed, in the shot where he begins to fall into the pit, there's no reflection of Obi-Wan's lightsaber blade on the shiny floor. This can also be seen in the shot where he rushes over to Qui-Gon. (01:59:15)
Continuity mistake: When Anakin and Obi-Wan walk up to greet Palpatine on Naboo, in the wideshot, a Republic guard is passing by them. In the close-up, the guard is gone. (02:00:40)
Revealing mistake: After the final battle scene when the Jedi council come down to the Naboo city, as they are leaving the spacecraft there is a figure in the background who is obviously supposed to be Mace Windu, but is definitely not Samuel L. Jackson. The man is African-American, bald and dressed in Windu's clothes, but is not him. Perhaps Mr. Jackson was unavailable that day. (02:00:50)
Suggested correction: There is no indication that this man is "supposed to be" Mace Windu. First, several adult Jedi wear similar clothes. Second, during the funeral service for Qui-Gon, there are two rows of people sitting in a large, round room. We don't see all of them on screen. No reason why another human Jedi, who looks similar to Windu, could not be there.
Revealing mistake: When Palpatine meets Amidala on Naboo in the crowded scene Anakin is different from the original actor. Seen in the whole scene with his profile and front shot. (02:05:54 - 02:06:24)
Revealing mistake: When the Queen blasts the window to gain entrance into the upper floor of the palace, a shot from down the corridor reveals that the window was already open before the sparks and smoke appeared on screen.
Continuity mistake: After the race, Anakin's face is dirty. When his mother kisses him, his face cleans itself between shots.
Continuity mistake: After Qui-Gon is struck by Darth Maul's lightsaber, he drops down, and his lightsaber is lying on the floor. In the shot where Maul turns around to face Obi-Wan, the sabre is not lying in the same place as before (seen from the colours of the floor), and the activation button faces upwards, which it didn't do in the previous shot. In the next shot of Qui-Gon, his lightsaber is now closer to him than in the previous shot.
Revealing mistake: When Qui-Gon is attacked by Darth Maul for the first time, he escapes by leaping onto his ship which quickly takes off. As they zoom up into space, he discusses the mystery attacker with Obi-Wan. However, the lighting from outside the windows never changes giving the impression that they are static on a set rather than whizzing up into space.
Continuity mistake: In the scene in the podracer hangar after the Podrace, the existence and position of the people and objects keeps changing between shots.
Audio problem: When Obi-Wan rushes through the Force Doors, after Qui-Gon's death, to face Maul, watch and listen carefully. Obi swings his lightsaber three times in rapid succession, Maul blocks all three attacks. The lightsabers appear to contact, there is even the almost subliminal flash from the beams hitting each other, but the sound crew only inserted two contact sound effects, and those two sounds are slightly out of sync with the actual movements.
Other mistake: In the ending credits, Keira Knightley's first name is misspelled "Kiera."
Continuity mistake: After Darth Maul falls off the walkway, Qui-Gon jumps down after him, and as they continue the fight, there are several vertical beams behind them. The number of beams and their size change between shots.
