But what is it going to be called?

‘Episode III’ in a Theater Not So Far Away
†
LOS ANGELES (Zap2it.com) – The Force is strong with “Star Wars: Episode III.”
The sixth film in the sci-fi franchise by George Lucas will conclude the saga when it is released in the United States and Canada on Thursday, May 19, 2005, according to Lucasfilm.
The almost-simultaneous worldwide release follows tradition in North America, where the previous five films were also released in May, starting with “Star Wars: Episode IV – A New Hope” on May 25, 1977. In Japan, “Episode III” will be released in July, the traditional month for the country’s Star Wars premieres.
“Episode III” continues the Clone War with Anakin Skywalker (played by Hayden Christensen as the future Darth Vader) finding himself dangerously close to the dark side of The Force and butting heads with Obi-Wan Kenobi (Ewan McGregor). Also reprising their roles are Natalie Portman as Senator Amidala, Samuel L. Jackson as Mace Windu and Frank Oz as the voice of the olive-hued, pint-sized Jedi master Yoda.
Lucas’ “Star Wars: Episode II – Attack of the Clones” made over $310 million at the U.S. box office in 2002.
