Continuity mistake: Darth Maul's neck is black, but when he is talking to Darth Sidious on Coruscant, his neck is flesh-toned. (00:38:45)
Continuity mistake: During the podrace, Anakin is in front of Sebulba and has him on his tail. One view looking towards Anakin you can see Sebulba's pod in the background, but the driver's seat is empty. (01:04:10)
Continuity mistake: Obi-Wan's braided hair keeps changing sides, and getting longer and shorter, most noticeably in the scenes around the underwater city. (00:13:40)
Continuity mistake: When the flags are first brought out onto the course, we see C3PO carrying Anakin's flag (a blue cross) three back from the front. Then in a closeup of him, he's suddenly between two different flag carriers. Worse still, in a wide shot of the flag carriers leaving the course before the race, he and the flag have disappeared completely. (00:54:20)
Continuity mistake: When Anakin attaches 3PO's right eye, one shot has the eye in his left hand, then the angle changes and the eye is being applied with the right hand. (00:37:20)
Continuity mistake: When Palpatine and Queen Amidala are conversing in his office (when Palpatine refers to Valorum having 'very little real power') his outfit switches from a green breasted cloak with a blue collar area to a green breasted cloak and dark green collar. It switches back after one shot. (01:23:10)
Continuity mistake: When Amidala and some other guards use the ascension guns from the palace windows seven of them go up, when they are running along the corridor after coming off the window-ledge, there are about 13 or 14 of them. Then finally when they are surrounded by the droids, there are about 10 or 11 of them and Captain Panaka is not there. (01:53:30)
Continuity mistake: In the chamber room near the end of the movie, after the Queen throws the guns to everyone and goes to address the Viceroy, she starts to walk away from her chair. While she is doing that, you can distinctly see her lose her footing and slip on the floor. In the next edit she repeats this movement without slipping. (01:56:10)
Continuity mistake: When Qui-Gon and Obi-Wan are landing the Naboo ship on Tatooine to repair it, watch the landing closely. The shadow of the ship is already on the ground before the ship lands on it. Also the ship tilts back and forth during the landing but the shadow never changes or moves. Also, if you look carefully at the dust (which was shot using a helicopter landing) some of the dust being flicked up actually passes through the ship. (00:29:55)
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.
Continuity mistake: When Obi-Wan and Qui-Gon are talking to Jar Jar in the forest, Obi-Wan's hair is wet. But when Jar Jar says, "This way, hurry." Obi-Wan's hair is completely dry. In the next shot, it's wet again. (00:12:15)
Continuity mistake: Sebulba breaks the stabilizer on Anakin's Pod before the Podrace begins, but in the following shots where he's talking to Anakin, you can see in background that the stabilizer is unbroken. (00:54:55)
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.
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)
Continuity mistake: Right before Darth Maul kicks Obi-Wan off the walkway, there's a wideshot where Obi-Wan and Qui-Gon are fighting Maul on a straight part of the walkway. In the following shots, all three of them are suddenly standing on a round part of the walkway. (01:50:45)
Continuity mistake: Near the beginning of the film, there's a few shots of the droid army landing on Naboo, with one shot of one of those hover tanks moving out of the landing ship towards the camera. In front of it are three droids in a line who are also walking towards the camera. Unfortunately, the tank is moving much faster and is bearing down on the droids with no sign of stopping - unfortunately the shot changes just before it runs them over. (00:09:55)
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.
