Luke Skywalker Becoming The Next Darth Vader
Can you imagine a hero tuning into a villain during a trilogy? That would have been interesting! In one of the early drafts of Star Wars scripts, Luke Skywalker was originally written to be one with the dark side and defeat his father, Darth Vader. This way, he would defeat Vader after threatening Princess Leia in order to save her.
In this plot, Luke Skywalker would become a Sith lord later on. This would happen after he defeats his mentor, Obi-Wan Kenobi. Even though this plot is epic and interesting, it had to be scrapped. Luke Skywalker was rewritten to be the chosen one who would come to help the rebel alliance in saving the entire galaxy.
