Star Wars: Shadows of the Empire is a multimedia project created by Lucasfilm Ltd. in 1996. The original idea was to create an interquel, a story set between the movies The Empire Strikes Back and Return of the Jedi (a time where no Star Wars novel had gone before), and to explore all commercial possibilities of a full motion picture release, without actually making the film. The venture paved the way for the theatrical release of the Star Wars Trilogy: Special Edition in the following year, and the later releases of the Star Wars Prequel Trilogy. (Wikipedia)
