Long has been the theory that George Lucas is actually a terrible filmmaker and that Star Wars Episode IV as was a fluke that was quickly corrected by hiring additional writers and new directors for the second two original trilogy flicks. There's no greater evidence to support this idea than the last three movies Lucas wrote and directed on his own, or the story he dreamed up for the last Indiana Jones. So then it should also come as no surprise that his original draft of Star Wars, originally titled The Star Wars: The Adventures of the Starkiller is kind of crazy and weird and probably was altered after notes from some of his more competent, famous filmmaking friends.
Luckily, that original was never filmed (though you can read the script here), but it will finally be realized in comic book form in the Dark Horse adaptation of The Star Wars, complete with old, aged Luke Skywalker and lizard-fied Han Solo. The 8-issue comic book will begin in September and Entertainment Weekly was able to grab some early art courtesy of Dark Horse which can be viewed above and below.
