7) Darth Vader’s Castle
Rogue One: A Star Wars Story took us to Darth Vader’s home on Mustafar, and with concept art for Star Wars: The Force Awakens showing that J.J. Abrams at least contemplated taking us to one of his castles, Star Wars: The Last Jedi needs to pay a visit to the one we’ve already seen. It’s already been teased that it’s built around some sort of Sith monument or weaponry and given Kylo Rey’s obsession with his grandfather, having him spending time in his home makes an awful lot of sense.
Regardless of your thoughts on the prequels, they made Mustafar an iconic and important part of the Star Wars saga, so taking us back there opens the door to a lot of very exciting storytelling possibilities. Linking this movie to the spinoff also establishes that these Anthology films are actually important and makes it clear to viewers that we can expect them to both tell standalone stories and link to the wider mythos.
