Senator Palpatine and Viceroy Nute Gunray are about the same height, and Darth Maul taller than both. But in one scene while Nute Gunray is sitting and Darth Maul is standing next to him, Darth Maul appears much shorter than usual.
After Daultay Dofine's first line of dialogue ("I knew it! They're here to force a settlement!"), he and Rune Haako switch voices. For the rest of the film, Haako speaks with Dofine's voice, and vice versa.
After the transport is destroyed in the hangar (near the beginning of the film) the scene cuts to Obi-Wan and Qui-Gon. The sound of their lightsabers being activated occurs before they even draw them from their belts.
Before Anakin shoots down the Destroyer Droids in the Theed hangar with the Naboo Starfighter, his mouth is shown moving before he says, "No, wait, here it is" while referring to the starfighter's laser cannon trigger.
When Obi-Wan rushes through the Force Doors, after Qui-Gon's death, to face Maul, watch and listen carefully. Obi swings his lightsabre three times in rapid seccession, Maul blocks all three attacks. The lightsabres 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 synch with the actual movements.
When Daultay Dofine says his first line of dialogue which is, "I knew it. They're here to force a settlement.", he speaks with the voice of Rune Haako, the Neimoidian who says, "Have you ever encountered a Jedi knight before, sir?"" shortly after.
Tey How says, "Sir, we're losing power. There is some problem with the main reactor... ." When Captain Dofine replies, "Impossible! I don't... .", his lips don't move until he is almost finished speaking. When they move, he appears to be saying "Impossible... ."
As Qui-Gon is weighing his options for payment, Anakin states, "there's a big race tomorrow..." However, the race is the day after tomorrow, as Anakin spends the next day getting his pod ready for the race and another evening follows.
After Darth Maul is chased into the large room with the chasm by Obi Wan and Qui Gon, he backs off to the edge and the camera goes back to a more distant angle. At that moment Darth Maul seems to almost stumble into the chasm and quickly catch himself again.
In the Nubian parade scene at the end of the movie, Anakin Skywalker is seen as a Jedi Padawan and sports a new haircut and a Padawan braid. The braid is considerably longer than his hair had been at any other point in the film.
When Anakin and Padme arrive at the pod racer hanger, Anakin is taller in the close-up shots, and Padme's hair is noticeably a little different. The close-up shots were done almost a year after the principal photography.
At the beginning of the Battle of Naboo, the Gungans create a shield around themselves using a number of shield generators on the backs of their mounted creatures. In a later scene, only one of these creatures has a shield generator on its back.
In the final fight scene with Obi-Wan and Darth Maul, Obi-Wan
leaps up from the hole, and grabs the lightsaber with his left hand. As he twists above Darth Maul's head, the lightsaber is in his right hand, when he lands, it's in his left hand again.
During the final fight between Obi Wan and Darth Maul, Maul force pushes Obi Wan into the pit. For the wide shot Maul is seen using his left hand to do this, but for the close up he is using his right hand.
When Qui-Gon and Obi-Wan are talking to Jar Jar when they first arrive on Naboo, Obi-Wan's hair is wet. When Jar Jar spins around and Obi-Wan is forced to duck, his hair suddenly becomes dry. In the next shot it is wet again.
During the fight over and around the droid control ship, Anakin says to R2D2, "I'll try spinning, that's a good trick." Anakin is seen to turn the flight controls to the left, but his craft spins to his right. In an earlier scene (right after the auto pilot is disconnected) Anakin says, "Let's go left", turns the controls to the left, and the scene tilts to Anakin's left, showing that the controls are working backwards in one of the two scenes.
In the scene where Qui Gon is cutting through the door aboard the trade federation ship, two destroyer droids roll along the corridor towards them. Both droids are seen to deploy blue energy shields as they unfold; however, when Obi-Wan makes his comment about them having said shields, the camera cuts back to a brief shot of the two droids, during which the droid nearest the camera is seen re-deploying its shield.
When the Gungan army's front line of solders pull out their personnel deflector shield rims they all switch them on. This fills in the rims with a blue light. A few moments later looking out from behind the army's front line you can see the personnel deflector shield rims but not one is filled in with blue light.
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.
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.
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.
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.
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.
Just before the podrace Qui-Gon talks to Shmi on the platform. After the conversation, they walk towards the camera. Pay attention to the background, it's the same as the previous shot even though Qui-gon and the others are walking in the other direction.
During the pod-race, as the racers pass the start/finish line between laps, we see a view of R2, C3PO and Anakin's friends. R2 turns his head to watch the pods go by and it raises up about an inch and a half on one side, then seems to be stuck, the view changes and R2's head is swivelling fine, then we get another view of the wonky lid.
When Qui-Gon and Obi Wan are waiting for Jar Jar to get help from the Gungans we see shadows and light on their faces from the leaves on the trees. These shadows move constantly. In the close upos, they are entirely in shadow and there is no light showing through.
Just before Anakin's pod-racer gets stuck with Sebulba's, he is on Sebulba's right side. When they get stuck together in the next shot, Anakin is suddenly on Sebulba's left side without having changed positions.
After the final battle scene when the Jedi council come down to the Naboo city, as they are leaving the space craft 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.
When the flags are first brought out onto the course, we see C3P0 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.
During the dinner scene, when Anakin says, "I'm the only human who can do it", his wrist is bare. In the next shot, it's covered up by his sleeve, and the cup in front of him has moved closer to the edge of the table.
When the Queen's starship is approaching Naboo after leaving Coruscant, Ric Olié says, "Those are the forward stabilizers." In the next shot, Anakin's head is reaching higher over the back of his seat than it was in the previous shot.
After Qui-Gon is struck by Darth Maul's lightsabre, he drops down, and his lightsabre 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 lightsabre is now closer to him than in the previous shot.
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.
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.
After Obi-Wan falls off the walkway, he manages to grab hold of the edge of another walkway, and on the floor, there's a lit strip near his hands, to his right. When Qui-Gon and Darth Maul continue the fight, there's a wideshot where Obi-Wan (still hanging from the edge of the walkway) can be seen in the lower left hand corner of the screen. His hands are now further away from the strip, and are closer to the strip on his left.
During the fight against the Trade Federation Droid Control Ship, Anakin says, "Okay, let's go left" and turns the controls of his spacecraft to the left. The ship turns left. A few shots later, Anakin says, "I'll try spinning, that's a good trick" and turns the controls to the left, but this time, the ship turns right.
When Obi Wan is fighting with Darth Maul, Maul knocks Obi Wan back into the reactor pit using the force. When they first show Maul's hand, it is his right hand that takes off the lighsaber and pushes Obi Wan back. When the camera angle changes to show Obi Wan rolling backwards into the pit, Maul's left hand is clearly shown raised.
When Qui-Gon is fighting Darth Maul on Tatooine, Obi-Wan sits down in the cockpit of Amidala's starship. As the shot ends, his hand is up by the top of Ric Olié's (the pilot) seat. In the beginning of the next shot, his hand is down by his side, and Anakin's hand has suddenly appeared on top of the seat.
After Darth Maul sits down in his speeder, the probe droid flies past him, but in the previous shot, it was nowhere to be seen. It should have been visible, because of its position and the direction it was coming from.
As Obi-Wan is looking up at Darth Maul and Qui-Gon, they are fighting in the middle of the walkway. When Obi-Wan jumps up, they are at the doorway at the end of the walkway. They couldn't have reached the end of the walkway that quickly.
At the beginning of the Battle of Naboo, the Gungans create a shield around themselves using a number of shield generators on the backs of their mounted creatures. In a later scene, only one of these creatures has a shield generator on its back.
When Obi-Wan is hanging from the ledge in the abyss after Darth Maul knocks him into it, he sees Qui-Gon's lightsaber a distance from him and uses the force to grab it. Between shots, the lightsaber changes position on the floor.
During the climatic light-saber duel, just as Qui-Gonn and Obi-Wan have forced Darth Maul onto a ledge, look quickly and you will see that the red blade of Maul's light saber goes from being behind his waist to in front of it between shots.
When the laser cannon is lowered from the ceiling to fire at the Radiant VII (the Jedi's cruiser), as the copilot, Lieutenant Williams, says, "Captain, look!", his right arm is on the controls and Captain Madakor's head is on the left side of the top of her seat. In the next shot, her head is on the other side of the seat, and Williams' arm in no longer at the controls.
During dinner, as Anakin says, "I had a dream I was a Jedi", his arms are on the table. In the next shot, they're off the table, and there's a piece of cutlery in his food bowl, which wasn't there in the previous shot.
In the shot where Obi-Wan is looking up at Qui-Gon and Darth Maul, there are several vertical beams on the right side of the walkway. In the previous shots, the beams were on the left side. When Obi-Wan lands on the walkway after jumping up, the beams are again on the correct side.
At one point before Obi-Wan and Qui-Gon fight Darth Maul, Anakin stands up in the fighter he's in, Artoo's nozzle thing is on the wrong side of his dome, then it switches back to the right side the next time we see him.
In the Trade Federation spaceship, when Obi-Wan and Qui-Gon jumps from the ventilation shaft to the hangar, everything changes in the next shot. The boxes are different, Obi-Wan is closer to Qui-Gon, they are closer to the edge of the wall and the wall itself is different.
Obi Wan and Maul are fighting and Obi Wan stands side on to the Sith and puts his lightsaber in front of him and then directly vertical behind him, he then repeats this motion in close up, just before he cuts Maul's lightsaber in half.
When Jar Jar goes to retrieve the wrench that he dropped in the engine of Anakin's podracer, he moves his hand towards the upper part of the engine. In the next shot, he sticks his hand into the middle of the engine. In the following shots, his hand remains in the middle, but when he says that he's stuck, his hand is once again in the upper part.
When the battle droids first walk through the Gungan shield you see the Gungans throwing hundreds of boomas at the droids but in the wide shots of all of the droids not many droids have been hit and you can't see any boomas on the ground.
When Padme is cleaning R2D2 and chatting to Jar-Jar, the film's reversed in the final shot of Natalie Portman smiling. The easiest way to notice it is that when we're looking at R2D2, normally his lens is to the right of a blue/red light, but in the final shot the lens is now to the left of that light.
Before the pod race begins, as Jabba the Hutt says, "Welcome.", the woman to his right has her hand on the wall. In the next shot, she is no longer touching the wall and her head is turned in a different direction.
When the queen's ship lands on Tatooine you can see that there aren't very many big rocks near the ship but later when Panaka and Obi-Wan are talking about the storm they pass a row of rocks that wasn't there before.
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 lightsabre in half, the background changes and they are suddenly fighting on a different side of the pit.
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.
As someone else has noted, Obi-Wan's braid changes sides a few times in the movie. In the first scene with Jar Jar, his braid stays on the correct side of his head, but after he says, "If they find us, they will crush us" it goes from hanging in front of his shoulder to hanging behind it.
The shadows change angles all over the movie. First the shadows appear right beneath the characters, then in the next clip they are cast with an angle. And the shadows that ships and computer-animated animals cast are different from the "real" characters.
When the storm is approaching and Anakin offers them a safe haven, as they set off you can see R2D2 in the background and there are no tread tracks leading to him - he's obviously been carried there and set down to wheel away.
When the queen is being escorted by some droids after she has been captured, there is a shot of Obi-Wan and Qui-Gon watching the queen from a balcony. The shot shows the queen passing by them. Qui-Gon then takes a few steps and is somehow very far ahead of the queen and the droids. They didn't use the force run because Jar-Jar was right up with them.
When Anakin and Kitster are talking to Padmé in the Podracer hangar, Kitster says,"Finish the race, of course" and in the background, Qui-Gon walks into the shot from the right and touches the arm of an alien. In the next shot of the boys, Qui-Gon enters the shot from the right again, and touches the alien's arm a second time.
When R2-D2 and three other astromech droids fixing the Nubeing ship, Jar-Jar is talking to them and there is a black one. This black one turns into a blue one when they are fixing the ship. It's the second one to get blasted.
When Obi-Wan falls off the walkway during the duel with Darth Maul, his lightsabre lands on a lit strip of the floor. A few shots later he jumps up and retrieves his sabre, which is now resting on a dark area on the floor. Even if the sabre continued to roll on the floor between the shots, it couldn't have ended up in this position.
When Anakin's friends show up while he is working on the Pod, in the second shot, the youngest girl is standing in front of Wald (the young Rodian), to his left. In the same shot, Padmé begins to walk past them and Anakin begins turning right. In the next shot, the girl is standing on Wald's right, the older girl is standing further away from him, Anakin has turned the other way and Padmé is nowhere to be seen. Then, when Anakin says, "That isn't the half of it", the youngest girl is crouching down, but in the next shot, she's standing straight up. And when the oldest girl says, "You've been working on that thing for years", she is standing closer to Wald than in the previous shot, and the other girl has moved from his right to in front of him.
When Padmé is to come with Qui-Gon after the Queen's ship has landed on Tatooine, he says, "This is not a good idea", and something blurry flies by in the upper right hand corner. It is not there before or after.
When the queen is being escorted by some droids after she has been captured, the shadows change completely. When we first see everyone walking past, their shadows stretch ahead of them, but when we see them walking towards Obi-Wan and Qui-Gon, the shadows are really elongated and at an angle.
When the Queen and her entourage enter the hangar where the pilots are being held, Jar Jar is not among the first people who walk in. In the next shot from behind, he is suddenly walking in the front part of the group.
During the Podrace, the announcer says, "Skywalker's been forced onto he service ramp," and the people standing behind the gate begin to run away. At the end of the shot, they are still behind the gate, but in the next shot, all of them have moved away from it.
After Darth Maul falls off the walkway, Qui-Gon jumps down after him, and there are several vertical beams behind them. In the next shot, they have suddenly moved past them, but in the following shot, they are fighting in front of the beams again.
When Qui-Gon and Obi-Wan are fighting battle droids in the Trade Federation ship, Nute Gunray says, "I want droidekas up here at once." As he says this, he turns his head, causing the "straps" hanging from each side of his headgear to hang slightly behind his shoulders. In the next shot from behind, they are hanging in front of his shoulders like they normally do.
When Obi-Wan, Qui-Gon, and Darth Maul get cut off from each other in the corridor and Qui-Gon kneels down, Obi-Wan is standing in the background with his lightsabre pointed downwards. In the next shot, it's pointing upwards.
When Anakin says goodbye to his mother, his shirt collar keeps moving up and down his neck between shots. The easiest way to see this is to watch his necklace, which is more covered up by his shirt in some shots than others.
When Darth Maul is fighting with Qui-Gon, only one blade of his lightsaber is on and on the other side there is just a flat end, with no hole. When he fights with Obi-Wan and Qui-Gon in the palace, there is now a hole at both ends.
When C-3PO meets R2-D2 for the first time, Natalie Portman and Jake Lloyd (Padme and Anakin) can be seen in the background. They are obviously NOT watching the action in the foreground, but instead Mike Lynch, the robotics operator, moving 3PO about.
The droid army is entering the city it cuts to the scene where the Queen is looking out of the window in her palace. As it shows her approach the window you can clearly see a large ILM (Industrial Light & Magic) sign written in what looks like red spray paint at the bottom right hand corner of the screen.
When Queen Amidala is standing before a big window (she watches the Trade Federation enter the city) she is wearing a dress with lights at the bottom. Behind her the power cable of those bulbs is visible.
When the engines start turning on Anakin's pod racer, they are turning the wrong direction. They should be turning so that the fan blades will force air into the engine, but the direction they are turning, air will blow out the front of the engine.
Many naturalists complained that Watto's wings weren't big enough to lift his body in flight. George Lucas explains that Watto's digestive system filled his rotund belly with helium, making Watto a blimp, not a bird.
It is established early in the film that Qui-Gon Jinn and Obi-wan Kenobi have the ability to dash several feet across in a few seconds yet it never occurs to Obi-Wan to use it in the hallway with the revolving forcefields to reach Qui-Gon and Darth Maul in time. Of course, if he did, he could have crashed right into a force field as they turn on and off so quickly.
During the final lightsaber battle, the red force fields can be regularly seen opening and closing before Obi-Wan emerges from them. After he does, they cannot be seen or heard opening or closing again. However, the force fields are not necessarily on permanently and may have simply finished a regular or semi-regular cycle when Obi-Wan emerges from them.
When listing candidates for Chancellor, Captain Panaka includes "Bail Antilles of Alderaan." Some viewers think he means Bail Organa of Alderaan (played by Jimmy Smits in later movies). However, there is nothing unusual about two men from the same province having the same first name. The script explains that these are indeed two different characters.
It is not clear in what way, if any, the Naboo and the Gungans are symbiotic. However, this is not a goof as all the audience needs to know is that they share the planet of Naboo together and have clearly made it a thriving world with its natural beauty intact.
Palpatine comes to power after the vote of no confidence of the Supreme Chancellor, following Vallorum's decision to perform a lengthy investigation of the Trade Federation's alleged crimes on Naboo. However, the Chancellor's own ambassadors (Jedi) had already been to Naboo and could have easily testified to, and confirmed, the Federation's illegal actions.
The premise behind Anakin having to win his pod race is due to the fact that Watto wouldn't accept Republic Credits from Qui-gon Jinn in payment for the parts their ship needs. Surely there is at least one person in the spaceport (a banker perhaps?) that would be willing to exchange local currency for the Republic credits. Especially since Qui-gon was willing to use the Force to "persuade" Watto to accept the currency he had.
Qui Gon believed that Anakin was the chosen one of prophecy who would bring "balance" to the force. However, at the time, the Jedi vastly outnumbered the Sith. So, it was directly against the Jedis' self-interest to achieve balance. If they had wanted parity between Jedi and Sith, all they had to do was to stop training Jedi.
As Qui-Gon, Padme, and R2 enter Anakin Skywalker's home Qui-gon introduces himself to Anakin's mother. As Qui-Gon says, "I'm Qui-Gon Jinn", Padme mouths these same words. This might not be visible in the pan and scan version of the film.
When Darths Maul and Sidious are conversing on Coruscant ("At last we will have revenge!"), Maul's neck is visible beneath his cloak, and is flesh-toned. Everywhere else in the film, his neck is black.
When Qui-Gon and Jar Jar are eating the meal at Anakin's house, his mother goes around the table pouring water into everyone's cups. She pretends to pour it into Jar Jar's computer-generated cup, and it sounds as if she does, but no computer-generated water has been added into the scene.
When Jar Jar Binks is leading Qui-Gon Jinn and Obi-Wan Kenobi to the underwater city, Qui-Gon Jinn asks, "How much further?" to which Jar Jar Binks states they must go under water. Qui-Gon Jinn and Obi-Wan Kenobi make motions to get out breathing apparatus but it can be seen that they have been carrying them in hand for the entire scene, even before finding out the city was underwater.
After R2-D2 repairs the shield generator, there is a scene where Padme is cleaning up the droid and talking to Anakin. In the last shot of this scene, the film is reversed (mirror image) - evident from R2-D2's features.
A green Landspeeder similar to Luke Skywalkers in Episode IV is visible when Qui-Gon's party enters Mos Espa. It should be floating above the ground, but two of it's three wheels are visible, despite two black clad humans standing in front of it trying to cover up the wheels.
When Qui-Gon is talking to Jar Jar for the first time, they are walking through the forest. A branch with leaves comes up and Jar Jar dips his head to avoid it, but his eye and part of his head go through the leaves.
When Qui-Gon delivers the hyperdrive, Obi-Wan's braid is on the left side and not the right. Evidently, this was done deliberately with the intention that the shot would later be flopped, but for some reason it never was, leaving the braid on the wrong side.
After everyone leaves Tatooine after the short stay they land on Coruscant in the middle of busy air traffic. Unfortunately, the ship that they fly in (the Nubian), with its incredibly shiny and mirror-like appearance does not reflect the bustling traffic above, nor the people walking out of it. It only seems to reflect the basic landscape.
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.
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.
When the Queen is escorted down the stairs in the Theed Royal Palace, right before Nute Gunray says, "Process them.", watch the space between Sabé (the Queen's decoy) and Captain Panaka, before a handmaiden and one of the Queen's guards block the view; the battle droid behind Sabé doesn't cast a shadow on the railing, as everyone else does in this shot.
During the second lap of the Podrace, the announcer says, "Skywalker's spinning out of control" and there's a shot of the audience. After Anakin has won the race, the same shot is used again. This can be seen, for example, from that the people on the steps make the exact same movements in each shot.
When the Gungan army set up their shield at the Naboo plains, you see the Trade Federation tanks coming over the hill. When the camera turns to behind the tanks, you see the bottom of one of the beige tanks disappear slowly.
When Qui-Gon and Obi-Wan are being gassed, Nute Gunray's hologram says, "Destroy what's left of them." After he says this, watch the battle droid on the left side of the screen closest to the hologram. One of its fingers goes through the barrel of the gun it's holding.
In the final scene of the movie, you can see a girl in a peach colored dress standing behind R2-D2 and Anakin. A few shots later, she is seen in the foreground of a shot of children throwing confetti down onto the parade. A few shots later she is back behind R2-D2, Anakin, and the Queen.
After the Trade Federation is defeated, Padme's decoy is again playing the role of Queen Amidala when she is speaking to the Viceroy after their defeat, even after Padme revealed herself to the Viceroy as the real Queen Amidala in the throne room.
