While George Lucas‘ sequel trilogy never came to fruition, the villains he planned to use have been brought to life by an exceptional Star Wars cosplay. Following the conclusion of the Star Wars prequel trilogy, Lucas was initially adamant that there was no Episode VII and that he would never allow another filmmaker to continue his saga. However, Lucas changed his mind when he sold the franchise to Disney in 2012, who quickly set Lucasfilm to work on the Star Wars sequel trilogy. Lucas had even developed his own treatments with Darth Maul and Darth Talon as the main villains.
