The Star Wars prequel trilogy, colloquially referred to as the prequels, is a series of epic space-opera films written and directed by George Lucas. It was produced by Lucasfilm Ltd. and distributed by 20th Century Fox. The trilogy was released from 1999 to 2005 and is set before the original Star Wars trilogy (1977–83), chronologically making it the first act of the Skywalker saga. Lucas had planned a prequel trilogy (as well as a sequel trilogy) before the release of the original film, but halted major Star Wars films beyond the original trilogy by 1981. When (CGI) had advanced to the level he wanted for the visual effects he wanted for subsequent films, Lucas revived plans for the prequels by the early 1990s. The trilogy marked Lucas's return to directing after a 22-year hiatus following the original Star Wars film in 1977, as well as a 16-year hiatus between the classic and prequel trilogies.
The trilogy consists of Episode I – The Phantom Menace (1999), Episode II – Attack of the Clones (2002), and Episode III – Revenge of the Sith (2005). The films follow the training of the powerful youth Anakin Skywalker (the father of the original trilogy protagonists Luke Skywalker and Leia Organa) as a Jedi under the tutelage of Jedi Masters Obi-Wan Kenobi and Yoda, his fall to the dark side of the Force and rebirth as Darth Vader. The trilogy also depicts the corruption of the Galactic Republic, the annihilation of the Jedi Order, and the rise of the Empire under the secret Sith Lord and future Galactic Emperor Darth Sidious. The first two films received mixed reviews, while the third's reception was more positive. However, all three enjoyed box-office success.
According to original trilogy producer Gary Kurtz, loose plans for a prequel trilogy were developed during the outlining of the original two films. In 1980, Lucas confirmed that he had the nine-film series plotted, but due to the stress of producing the original trilogy and pressure from his wife to settle down, he had decided to cancel further sequels by 1981.
