Cast

• Ewan McGregor as Obi-Wan Kenobi: Obi-Wan is a General for the Galactic Republic and is a Jedi Master who sits on the Jedi Council. He often travels and performs missions with his best friend and former Padawan, Anakin.
• Hayden Christensen as Anakin Skywalker / Darth Vader: Anakin is a recently-knighted Jedi and hero of the Clone Wars. Upon learning of his wife's pregnancy, he begins to have recurring visions of her dying in childbirth. Because similar visions accurately foretold the death of his mother, he swears that he will do whatever it takes to save her, and in his determination, he falls to the Dark Side of the Force and becomes the evil Darth Vader. While many assume that James Earl Jones is the uncredited, briefly heard voice of Darth Vader at the film's conclusion, Jones, when specifically asked if he had supplied the voice, either newly or from a previous recording, told Newsday, "You'd have to ask Lucas about that. I don't know". However, the commentary on the DVD release states that, while the voice will always be uncredited, any true Star Wars fan "should know the answer".

As a result, the Senate has voted him vast emergency powers, effectively turning him into a dictator. By this time, he becomes a sort of mentor to Anakin, manipulating him into distrusting the Jedi.

It was announced in 2004 that Gary Oldman had been approached to provide the voice of General Grievous, however, complications arose during contract negotiations after Oldman learned the film was to be made outside of the Screen Actors Guild, of which he is a member. He backed out of the role rather than violate the union's rules. Matthew Wood, who ultimately voiced Grievous, disputed this story at Celebration III, held in Indianapolis. According to him, Oldman is a friend of Rick McCallum, producer of the Star Wars prequel trilogy, and recorded an audition as a favor to him, but was not chosen. Wood, who was also the supervising sound editor, was in charge of the auditions and submitted his audition anonymously in the midst of 30 others, under the initials "A.S." for Alan Smithee. Days later he received a phone call asking for the full name to the initials "A.S." An internet hoax said John Rhys-Davies was considered for the role.
