Continuity mistake: During the scene where Padmé tells Anakin that she's pregnant, the shadows keep changing between shots.
Continuity mistake: When Anakin and Count Dooku are duelling, as Dooku says, "I sense great fear in you, Skywalker", Anakin's lightsaber is slanted upwards, but in the previous shot, it was slanted downwards. (00:13:00)
Continuity mistake: When Palpatine and Windu are fighting they end up standing stuck face to face with their lightsabers. At first Palpatine's lightsaber is pointing to the right side of Windu. When it cuts to a close-up of Windu Palpatine's lightsaber is pointing to Windu's left. (01:09:05)
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.
Continuity mistake: When Palpatine and Anakin, who's carrying Obi-wan, climb through the elevator shaft we see Palpatine put his left hand down pushing himself up. When it cuts he does the same again. (00:15:40)
Continuity mistake: When Anakin visits Padmé before going to Mustafar, as he says, "Have faith, my love." he's touching the side of her head. In the next shot, his fingers change position. (01:25:25)
Continuity mistake: When Yoda is done with the holographic meeting with the rest of the Jedi Council about sending Obi-wan after Grievous, he gets up and walks to the trooper behind him. We also see Chewbacca follow him, stop, and cross his arms. When it cuts to the trooper saying, "The droids have started up their main power generators," we see Chewbacca still walking and stopping, but this time he doesn't cross his arms, he places them on his hips. (00:47:20)
Continuity mistake: After having his nightmare/premonition Anakin wakes up, while Padmé sleeps beside him. The blankets on Padmé and the bed change position in the following shots. (00:29:50)
Continuity mistake: Just as Yoda starts fighting Darth Sidious, Yoda's walking stick disappears from the ground behind him.
Continuity mistake: When Obi-Wan and Anakin are fighting Dooku, Dooku throws Kenobi away. Before he is thrown, his light saber is in his right hand. When we see the shot of him on the ground, it is in his left. It is back in his right hand when he gets up. (00:12:50)
Continuity mistake: When Grievous escapes with the escape pod, three pods launch before his. When his goes off there are no signs of the other three anywhere ahead of him. They didn't didn't have enough time to change direction flying off screen. (00:20:30)
Continuity mistake: In the first shot of the scene where the Jedi Council refuses to give Anakin the rank of Jedi Master, Obi-Wan has both feet on the floor. In the next shot, one leg is crossed over the other. (00:33:35)
Continuity mistake: When Obi-Wan says to General Grevious, "Not this time. And this time you won't escape", you can tell that it is a flipped shot because the moles on Obi-Wan's forehead are the opposite way round to how they are normally.
Continuity mistake: In the fight scene between Obi-Wan and Grievous, look closely at the lightsabers in Grievous' right hands as he ignites them. The one on top is an Obi-Wan hilt(blue) and the bottom is an Anakin hilt(green). Throughout the fight, these two sabers alternate colors constantly between shots. When Grievous' hand is severed the second time, he drops the Obi-Wan(green) and retains the Anakin(blue).
Continuity mistake: When Anakin runs and jumps off the platform as it descends the lava bank, the glove is on his right hand, but in the next shot when he lands on the DLC-13 mining droid, the glove is suddenly on his left hand instead. (01:57:53)
Continuity mistake: When Anakin, Obi Wan and Palpatine are brought to General Grievous, as they are walking in just as Grievous says "ah yes" Anakin and Obi Wan turn to the left while Palpatine stands a little away from them. When Grievous says "General Kenobi, we've been waiting for you" Anakin and Obi Wan are turning left again.
Continuity mistake: The emperor sits up as he's using force lightning on Mace then a few seconds later he sits up again.
Continuity mistake: As Palpatine stands to face the Jedi, his right hand starts to turn around for his lightsaber. In the close up, his hand turns around again.
Continuity mistake: During the fight scene between Obi-Wan and Grievous, Grievous has the lower half of his left hand and upper half of his right hand severed during the saber duel. However, as he gets into his vehicle, the damage done to his right hand reverses itself and he is missing the lower half instead.
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.
