Star Wars III - Revenge of the Sith is a science fiction film not set within the Solar System which was released in 2005 and is directed by George Lucas.
The Chancellor Palpatine has been kidnapped in a spectacular sweep on the Senate by the droid army of General Grevious, a multi-light sabre wielding cyborg. Palpatine is held on board the Invisible Hand, the flag ship of the Trade Federations space navy. Anakin Skywalker and Obi-Wan Kenobi lead a daring operation to rescue the Chancellor. The two Jedi Knights confront Count Dooku first but when Obi-Wan is knocked unconscious, Anakin faces Dooku alone. Against his better judgements, Anakin executes the Count after being persuaded by Palpatine to do so. When the Jedi Knights find and confront General Grevious, the latter smashes glass and escapes into space.
Obi-Wan is sent to Utapau to track down and kill the General once and for all. Obi-Wan is successful and returns jubilant. Yoda travels to Kashyyyk to provide assistance to the Wookies as they begin the fight against the droid army, Whilst Obi-Wan is hunting the General, Anakin continues to get closer to the Chancellor. Anakin is plagued by nightmares that Padme will die during childbirth and seeks ways in which this can be prevented. The Chancellor suggests the dark side of the force as it is darker and a more powerful force than what the Jedi use, which can be used to save Padme. Anakin notifies Mace Windu who the Chancellor really is, a Sith Lord. When a team of Jedis go to arrest the Chancellor, the Chancellor reveals himself to be a Sith lord and despatches three of the four Jedis leaving Mace alone. The Sith Lord uses electricity from his fingers in an attempt to kill Mace but he is too strong for the Sith. The real face of Palpatine is revealed. Mace is about to kill the Chancellor, Anakin returns to the room and chops off Maces hands. The Sith Lord elevates Mace into the air and fires him off into the night. Anakin is given the name Darth Vader then instructed to kill every Jedi alive. He visits the Jedi Temple and kills every young Jedi. Palpatine initiates Order 66 which is the instruction for the Clone Army to turn on the Jedis and kill them.
With only Yoda and Obi-Wan left alive, they return to the Temple to send a message to remaining the Jedis of the danger. Palpatine goes to the Senate and assumes the title of Emperor Palpatine. Obi-Wan, C-3PO and Padme journey to Mustafar, a planet on the outskirts of the galaxy to confront Anakin. Anakin had been instructed to go there to kill all the Separatist leaders which he does easily. Padme attempts to reason with Anakin but he sees her as being an enemy and attempts to strangle her. Obi-Wan watches Padme plead with Anakin but only intervene once Padme has been hit. The two Jedis fight it out across the lava streams of the planet. Yoda meanwhile fights against Palpatine to a deadlock so Yoda leaves. Anakin loses the fight and ends up having his arms and legs cut off with Obi-Wan walking away as he burns. The Emperor senses the pain in Anakin and leaves for the planet. Anakin is recovered and taken back to Coruscant for rebuilding into Darth Vader as we know him. Padme gives birth to twins, she was only expecting one. The boy Luke Skywalker is taken to his Aunt and Uncle on Tatooine. The girl Princess Leia is given to Bail Organa for raising. Yoda retreats to Dagobah.
