Star Wars: Episode III – Revenge of the Sith is a 2005 American epic space opera film written and directed by George Lucas. It is the third installment in the Star Wars prequel trilogy and the sixth film in the overall Star Wars saga. The film takes place three years after the start of the Clone Wars and follows Jedi Anakin Skywalker's tragic fall to the dark side, becoming Darth Vader, and the rise of Darth Sidious and the Galactic Empire. The plot revolves around Anakin and Obi-Wan Kenobi rescuing Supreme Chancellor Palpatine, Anakin's increasing mistrust of the Jedi Council, Palpatine's manipulation of Anakin to join the Sith, the execution of Order 66 that leads to the massacre of the Jedi, and the final duel between Obi-Wan and Anakin on Mustafar. The film ends with Padmé Amidala giving birth to twins Luke and Leia before dying, and Obi-Wan and Yoda going into hiding as the Empire rises. Themes in the film include political intrigue, the temptation of power, and tragedy akin to a Faustian pact, with a heavy emphasis on Anakin's internal struggle and transformation. The film is noted for its darker tone compared to other Star Wars movies, portraying the downfall of heroes and the birth of a villain. Key cast includes Ewan McGregor as Obi-Wan Kenobi, Hayden Christensen as Anakin Skywalker, Natalie Portman as Padmé Amidala, and Ian McDiarmid as Chancellor Palpatine/Darth Sidious. Revenge of the Sith completes the prequel trilogy and directly leads into the original Star Wars trilogy beginning with Episode IV: A New Hope.
