As more time passes since the release of Star Wars: The Last Jedi, several discussions about events in the film are taking place. Thankfully, director Rian Johnson seems to be addressing many of them head-on. Warning: Spoilers for Star Wars: The Last Jedi follow.
Days after explaining why he chose not to feature the Knights of Ren in the movie, Johnson is now sending a message to those who think Luke Skywalker projecting a vision of himself to fight Kylo Ren makes no sense in the Star Wars galaxy. As it turns out, not only does it make sense, but the director had the books to prove it.
In a series of tweets, Johnson went to his own personal library, where a copy of The Jedi Path is kept. The book, written by Daniel Wallace, is a guide to Jedi history and powers written for Lucasfilm. It's essentially a real-world version of the sacred Jedi texts. In it is a passage about doppelgangers.

In full, the passage reads, "Doppelganger, or Simulfuturus, permits a Jedi to create a short-lived duplicate of himself or herself or an external object that is visually indistinguishable from the real item. Those who have perfected the ability can create phantoms of any person of their choosing or trick an enemy into seeing more objects, such as droids, than are actually present."
Clearly, Johnson did his homework when it came to crafting the script to Star Wars: The Last Jedi. As for whether it changes how fans view the film is up to them. The director continuing to discuss the film a month after release just goes to show how important the subject matter is to him, though.
