Continuity mistake: The position and existence of the dead bodies in the control centre on Mustafar keep changing between shots, especially during the duel between Anakin and Obi-Wan.
Continuity mistake: When Obi-Wan and Anakin are fighting on the table in the control centre, they are standing/crouching in a different position from the previous shot after every time they kick each other. For example, when Obi-Wan kicks Anakin for the second time, as the shot ends, both of his feet are on the table, but in the next shot, one of his feet are up again.
Continuity mistake: The scar over Anakin's eye changes throughout the movie. For example, when he is talking to Yoda about his premonition, the scar is different from the previous scene - the part below his eye moves slightly down and lengthens.
Continuity mistake: When Anakin and Padmé are talking on the couch after Anakin is appointed to the Jedi council, they keep changing position between shots, depending on the angle of the camera. The easiest way to see this is to watch the red cloth hanging behind them on the couch. In some shots it is behind Padmé, in other shots, it is behind Anakin.
Continuity mistake: In the scene where Luke and Leia are born, the blankets under the babies are arranged differently between several shots.
Continuity mistake: When Padmé is talking to Anakin on Mustafar, her right hand keeps changing position between shots.
Continuity mistake: When Anakin is talking to Yoda about his premonition, the shadows and the intensity of the sunlight shining through the windows keeps changing, depending on the camera angle.
Continuity mistake: Just before leaving in his spacecraft to go and fight against general Grievous, Obi-Wan Kenobi is seen being briefed by Clone Commander Cody. During the briefing, you can see that at least one of the clone troopers on the right does not have the same head as the Clone Commander. But, when Obi-Wan climbs onto the wing of his spacecraft and enters it, the clone troopers on the right suddenly all have the same head as the Clone Commander.
Continuity mistake: In the beginning, when Obi-Wan and Anakin are returning after saving Palpatine, you can see their ship approaching the platform is about to go under a large shadow. But in the next shot, it takes quite a while for the shadow to even touch the ship, and the shadow is of a different position/size. (The shadow is from an over-hang above them, for other ships I assume).
Continuity mistake: In the Palpatine/Yoda lightsaber duel, during the second time they lock sabers, Palpatine's blade is pointed down, then in a closeup of his face, his blade is at an upward angle. Then when it cuts back to Yoda, his blade is pointed down again even though blades were constantly locked. This may only be noticeable in widescreen.
Continuity mistake: In the Anakin vs Obi-Wan fight scene, when they are fighting in the small hallway, Anakin's lightsaber marks the wall, but in future shots the mark on the wall has disappeared.
Continuity mistake: When Anakin is gripping Obi-Wan's right arm as he's choking him, his hand changes position on his arm a few times.
Continuity mistake: On Utapau when Obi-Wan is looking down upon Grievous and the Separatist leaders, you can see Grievous is very far away (judging by the floor panels, perhaps 10 floor panel widths taking into account the diagonal angle at which Obi-Wan is looking at Grievous). Obi-Wan proceeds to jump straight down, but in the next shot where Obi-Wan lands, Obi-Wan is only 1 floor panel width away from Grievous. Then, in the next shot which shows Obi-Wan surrounded by droids, he is now 2 floor panel widths away from Grievous.
Continuity mistake: When Padmé is lying unconscious after Anakin uses the Force to choke her, her position on the floor keeps changing between shots, sometimes dramatically. Watch the pattern on the floor and the container behind her.
Continuity mistake: During the Sidious and Yoda battle, the Emperor throws down several pods at Yoda that pile up on the floor.The pile changes in the number and position of the pods between scenes. This is especially noticeable when Yoda's lightsaber is shown falling to the ground, almost no pods are on the floor verses many pods when Yoda falls.
Continuity mistake: After the crash landing on Coruscant, Anakin, Kenobi, and Palpatine take a shuttle to the Jedi Council. In the first shot as the shuttle is landing, all shadows are parallel with the edge of the landing area. In the next shot when the shuttle doors open, all shadows have shifted 45-degrees clockwise.
Continuity mistake: During the scene where Padmé tells Anakin that she's pregnant, the shadows keep changing between shots.
Continuity mistake: In the very beginning, Obi-Wan and Anakin are flying near that big republic ship. Notice that it is calm everywhere even under the ship, but in the very next shot their are hundreds of ships and starfighters going by.
Character mistake: In the scene where Mace Windu and the other three Jedi attempt to arrest Palpatine, the first Jedi that Palpatine kills practically has his back turned to him, which is not something a Jedi Knight who is trained to be mindful of his surroundings would do. As we can see in the film, it takes Palpatine several seconds to stand up from his chair, draw out his lightsaber, threaten the Jedi, leap over his desk, and then lunge at them, meaning the Jedi had plenty of reaction time to avoid this.
Continuity mistake: Just as Yoda starts fighting Darth Sidious, Yoda's walking stick disappears from the ground behind him.
Chosen answer: Powerful force users seem to have some degree of control over their bodies even after death. In the later series, Luke's wife Mara Jade Skywalker only allows her body to disappear when her killer, and nephew Jacen Solo arrives at her funeral as a clue. Thus it appears that a powerful force user can simply choose if they wish their body to disappear.
