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: When Mace Windu and Palpatine are in his office after the lightsaber battle, Palpatine scrabbles into the corner as Windu paces towards him, ending up directly over him with lightsaber pointed at his throat. As Anakin walks in, Palpatine is already backed into the corner and Windu needs a few paces to get to him. (01:09:55)
Audio problem: In the scene where Anakin turns to the dark side, Darth Sidious says, "You're fulfilling your destiny, Anakin." As he says this, his head is shown from behind and is in shadow, but the words don't match the motion of his jaw, and his profile shows that his mouth is moving after the words are heard. (01:12:20)
Visible crew/equipment: After Sidious has killed Windu he speaks to Anakin. Sidious says, "Become my apprentice. Learn to use the dark side of the Force," and just as he says the words "the Force" you can see the tip of the boom microphone dip down above his head. This is visible on the 2005 full screen DVD. (01:12:30)
Continuity mistake: When Mace Windu and Palpatine fight, Windu backs Palpatine into the corner of the window. Note how close Windu is to Palpatine the whole time. Then from Anakin's perspective, Windu takes a few steps toward Palpatine, his saber pointed at Palpatine. When we saw it from the earlier perspective Windu never took those three steps toward a stationary Palpatine. (01:12:50)
Continuity mistake: After Darth Sidious kills Mace Windu, Anakin drops his lightsaber to the floor as he sits down. During the rest of the scene, the saber changes position on the floor twice. (01:13:20)
Audio problem: In the scene where Ki-Adi-Mundi is killed on Mygeeto, he yells, "Come on", but the words don't match the movement of his lips. (He moves his mouth like the lips of a human, even though he's an alien.). (01:18:05)
Continuity mistake: When Ki-Adi-Mundi is killed on Mygeeto, as the clone troopers stop and point their blasters at him, the area where they're standing consists mostly of sand. In the following shots, the sand is gone and there is only snow there (best seen in the shot from behind them). Even though it's snowing, the snow couldn't have covered up the sand that quickly. (01:18:10)
Continuity mistake: When the clone troopers kill Aayla Secura, the blue-skinned Jedi, their blasters are held differently between the second and third shot. (01:18:35)
Continuity mistake: As Anakin and the clone troopers attack the Jedi Temple, C-3PO says to Padmé, "The Chancellor's office indicated Master Anakin returned to the Jedi Temple." Padmé is holding her hand on her chest, and then begins to bring it downwards. In the next shot, her hand is near her throat. (01:20:35)
Continuity mistake: When C-3PO tells Padme that Anakin hasn't returned from the Jedi Temple and says he will be alright, you see Padme holding her right hand on her left waist. When it cuts she suddenly has her hand in front of her stomach and moves it back to her waist again. (01:20:40)
Continuity mistake: When Bail Organa is standing on the landing platform of the Jedi Temple, a clone trooper says, "I'm sorry sir. It's time for you to leave." and points his blaster at him. In the next shot, he is holding it much lower than in the previous shot. (01:21:15)
Continuity mistake: When Bail Organa is at the Jedi Temple when the young Jedi start fighting the troops, the Jedi chops off a trooper's foot. When Organa takes off, the foot is gone. (01:21:25)
Audio problem: When the young Jedi is killed and Bail Organa shouts "No." and climbs into his ship, shots can be heard but no lasers can be seen. (01:21:35)
Other mistake: When Bail Organa jumps into his speeder after watching the young Padawan get killed, as the speeder starts moving, he turns the steering control to the left for a few moments, but the speeder still goes straight forwards. (01:21:40)
Continuity mistake: In the scene where Plo Koon gets blasted by his Clone Troopers, the exterior shots show he is in an Episode II starfighter (closed/pointed bow, no small rear window on cockpit canopy- best seen as the Emperor gives the order), yet the interior shots of his cockpit show he is inside an Episode III starfighter (forked bow, small rear window on canopy- same as Obi-Wan's starfighter). (01:22:10)
Continuity mistake: When Tarfful uncovers the escape pod for Yoda he throws the bushes to the ground next to the pod. When Yoda enters the top the bushes are gone. (01:22:20)
Continuity mistake: In the first shot of the scene where Yoda leaves Kashyyyk, as Tarfull begins to walk towards Chewbacca, Yoda is several metres away from them. In the next shot, he is much closer to them, and Tarfull, who is still walking, is further away from Chewbacca than in the previous shot. (01:22:20)
Continuity mistake: When Yoda's escape pod takes off you can see the flaps on the pod being pulled in. Two shots later they are pulled in again. (01:22:55)
Continuity mistake: When Obi-Wan gets back to where he killed Grievous, in the overhead shot, you can see Grievous lying dead at least ten feet away from the ship. When it cuts to Obi-Wan climbing inside the ship Grievous is only a few feet away. (01:23:30)
Answer: Darth Vader has a special chamber in which parts of the suit can be removed for comfort. When he is not in the chamber he must wear it at all times in order to survive.
