During the early development of the 2017 film Star Wars: Episode VIII The Last Jedi, Luke Skywalker was originally meant to be visited while meditating in his hut by the Force spirit of an all-powerful Sith Lord described to have ruled over the Dark side of the Force from the Netherworld of the Force, pulling from behind the scenes "Supreme Leader Snoke's strings."
