There are alternative endings for Star Wars Episode VI: Return of the Jedi. So, does these deleted scenes become canon? In a deleted scene from the Revenge of the Sith, they show Grevious killing a jedi in front of Anakin & Kenobi. So, is it canon that this female jedi did die right then, even if it is not in the film? What is canon and what is not canon? If deleted scenes (that were deleted before the film was released to theatres) are not canon, what about scenes that are deleted and changed thirty years after the film was made? When George Lucas replaced the human actor with the animated slug of Jabba the Hutt in A New Hope, is Jabba looking like a human canon because this scene was kind of deleted and edited and modified years after the film was released. There are so many questions. It opens up a can of worms. I believe that the canon can be modified at will.
