Star Wars: Revenge of the Sith: The Visual Dictionary is a guide to Star Wars: Episode III Revenge of the Sith being the fourth book in Star Wars The Visual Dictionary series. Written by James Luceno and published by Dorling Kindersley. Published on April 2, 2005 along with the film novelizations and a number of other reference books, the book came out almost a month before the film, and as a result it introduced a number of elements from the movie prior to its release. It was republished as part of Star Wars: The Complete Visual Dictionary and is to be reissued with expanded content as Revenge of the Sith: The Expanded Visual Dictionary.
