Continuity mistake: When Anakin wakes up after his nightmare look closely at the design of their bed on Padme's side. In the close-up scenes of Padme sleeping the purple, brown and metal part of the bed is much thinner than in the wideshots. (00:29:30)
Continuity mistake: When Anakin wakes up from his nightmare Padme is lying next to him with her back exposed. When it cuts her dress is covering her back. (00:29:30)
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: When Anakin has just had the bad dream, Padme comes out wearing the nightdress with rows of beads around her arms. In one shot, the beads on her right arm are twisted, in the next, they're straight again. (00:30:20)
Continuity mistake: In the beginning of the scene where Anakin and Yoda are talking about Anakin's premonitions the outline of Yoda's shadow change between the shots. (00:32:05)
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 Palpatine appoints Anakin to be on the Jedi Council, as the first shot ends, they are quite far away from the large window and the column next to it. In the next shot, they are much closer to them. In the following shots from behind Palpatine, the background changes completely; for example, the window is gone, and a metal object and a shelf have suddenly appeared behind Anakin. Then, when Palpatine says, "I'm depending on you" they are suddenly standing in the doorway. (00:34:25)
Continuity mistake: When Anakin and Palpatine are talking and Palpatine says he is depending on Anakin to be "the eyes, ears and voice" for the republic, they are passing a column on Palpatine's side. When it cuts they pass it again. (00:34:45)
Continuity mistake: After Anakin has been turned down as a Master in the council, he is walking with Obi-Wan. While they are walking you can count them passing at least five windows. When it cuts to Obi-Wan saying "Anakin, I'm on your side, I didn't want to put you in this situation", you can see, by looking at the sun shining through the windows, that they have only passed three windows. (00:36:45)
Continuity mistake: When Anakin is denied the rank of master and he replies "what?", we see a ship near the bottom of the window that has just passed the window frame. In the next Anakin shot, the same ship is once again just passing the window frame. (00:37:05)
Continuity mistake: In the scene where Anakin and Padmé discuss the war and the Republic, some of the pillows on the couch change position slightly between the first two shots. (00:38:35)
Continuity mistake: After discussing whether Anakin is the chosen one or not, the ship Yoda, Obi-Wan and Windu are flying on goes in for landing. When it goes down there is no trace of clones on the ground where it is about to land. When it cuts several clones awaits them. Also two huge vehicles suddenly appears on the ground. (00:39:20)
Continuity mistake: While Anakin and Palpatine are talking at the performance, in one shot of Anakin we see Palpatine turn his head side on to the camera and drop his chin to his chest. In the very next shot he's holding his head high. (00:43:25)
Continuity mistake: At the performance when Palpatine and Anakin are talking, Palpatine says "he could even keep the ones he cared about from dying" while turning his head to Anakin, then his head stops. When it cuts back his head is still turning. (00:44:55)
Continuity mistake: When the Jedi Council discuss about Grievous being on Utapau and Yoda says "Act on this we must" Windu is sitting with his hands down. When it cuts he has his right hand to his face. (00:46:40)
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: When Anakin tells Obi-Wan, "I was arrogant, and I apologize." his hair is combed a certain way. As the conversation continues, his hair changes. (00:48:40)
Continuity mistake: When Anakin tells Padme he's found a way to save her, she says "Is that what's bothering you" while placing her hand on his chest and pulling it away again. When it cuts her hand is still on his chest. (00:51:30)
Continuity mistake: On Utapau when Obi-Wan gets off the creature before jumping down to Grievous, he pats the creature on its head. When it cuts his hand is nowhere near the creature. (00:54:45)
Continuity mistake: Before the lightsaber battle between Grievous and Kenobi, the area where they are standing and where Kenobi "drops" the weight on the magnadroids is a solid floor. The whole preparation-for-battle-scene does not include much movement from the actors. As soon as Grievous begins to move in on Kenobi, both of them are suddenly standing on some sort of bridge, without even passing the dropped weight. (00:56:15)
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.
