There have been so many little changes in the original Star Wars trilogy since their theatrical release because there have been so many “special edition” DVDs and Blu Rays and VHS tapes and LaserDiscs that have come out after the fact that it’s really hard to keep up with what the original movies showed in theaters.
Some of those changes since the theatrical release are good—the films look better because its in higher quality?—but many of those changes have driven fans crazy like how Han didn’t shoot first and the needless splicing of special effects to the original trilogy and the addition of Anakin to old scenes. And the worst thing is, you can’t watch the original versions of Star Wars anymore! Well, unless you get your hands on the Despecialized Edition. You can learn how to do that here.
