Star Wars Expanded Universe - Continuity and Canonicity

Continuity and Canonicity

The Expanded Universe is intended to be a continuation, and an expansion, on the six Star Wars theatrical films produced by George Lucas from 1977–2005. All EU material, combined with that presented in the films is meant to function as a complete story. However, in order to allow this story to function as a whole, it must be kept under in an order of continuity. Lucasfilm holds this of such high importance that a teams' sole job at Lucasfilm is maintaining continuity between Lucas's films, and the EU, which is written by many other authors and artists, many times out of order, and with many different ideas. Lucas, however, was free to go in any direction he wishes in his films to tell the story he intends. He acknowledges and supports the works of the EU but tells the stories he wants to tell in the six films. When asked in an interview his general opinion on the EU, he replied:

I don't read that stuff. I haven't read any of the novels. I don't know anything about that world. That's a different world than my world. But I do try to keep it consistent. The way I do it now is they have a Star Wars Encyclopedia. So if I come up with a name or something else, I look it up and see if it has already been used. When I said could make their own Star Wars stories, we decided that, like Star Trek, we would have two universes: My universe and then this other one. They try to make their universe as consistent with mine as possible, but obviously they get enthusiastic and want to go off in other directions. - George Lucas, from an interview in Starlog #337

George Lucas has also stated that as far as he was concerned the rule of the Sith ended with the death of Palpatine and freedom and democracy were restored to the galaxy with the Jedi's return, as he symbolized this by including the Senate building and the Jedi temple during the celebratory scenes at the end of Return Of The Jedi. He has stated that although he is aware of EU literature and welcomes its creativity, he has no part in the resurrection of Palpatine and the Yuuzhan Vong invasions (though this would contradict comments by Tom Veitch that it was Lucas himself who suggested they resurrect Palpatine instead of using the original idea of a Vader impostor in the Dark Empire storyline).

George Lucas retains ultimate creative control over the Star Wars universe. For example, the "death" of central characters and similar changes in the status quo must first pass his screening before authors are given the go-ahead. In addition, Lucasfilm Licensing devotes considerable effort to ensure continuity between the works of various authors across multiple companies. Nothing in the Expanded Universe is supposed to contradict the films or any other part of the Expanded Universe. Upon occasion, Lucas's new films, reedited Original Trilogy films, or statements have contradicted existing EU material, and several retcons have been used to fix these inconsistencies.

Some purists reject the Expanded Universe as apocrypha, believing that only the events in the film series are part of the "real" Star Wars universe. This line of thought is supported to the extent that some Expanded Universe material released before Lucas's prequel films drew erroneous conclusions that Lucas later corrected. However, elements of the Expanded Universe have been adopted by Lucas for use in the films. For example, the name of planet Coruscant first appeared in Timothy Zahn's novel Heir to the Empire before being used later in the prequel trilogy (although its pronunciation changed) - though the planet itself, under a different name, had existed in a previous version of the script to Return of the Jedi. Also, the Twi'lek Jedi Aayla Secura originally appeared in the ongoing Dark Horse Comics series Republic - apparently Lucas saw the cover which featured her and liked the look of her character so much that he included her in the Jedi battle at the end of Attack of the Clones, played by Lucasfilm employee Amy Allen, and her demise is later shown in the Order 66 Jedi Purge scenes of Revenge of the Sith. These examples sometimes end up confusing the issue, as they have blurred the lines between the Expanded Universe and "his world".

There are also minor disputes about what is, and what is not, part of the Expanded Universe. For example, the two Star Wars spin-off films: Caravan of Courage: An Ewok Adventure and Ewoks: The Battle for Endor were written by George Lucas and are films, but they are not one of the six main films in the series, so they are usually considered to be a part of the Expanded Universe.
