Once "The Last Jedi" ended and the credits rolled we were all left wondering the same question: Was Luke Skywalker really dead? Luke’s fate was, of course, delivered to us at the end of an exhilarating, and series-changing, third act in "The Last Jedi " Luke had, more or less, given in to the Force and found a way to create a hologram of himself while fighting Kylo Ren, it was all part of a distraction so that the resistance could sneak away. Eventually, as the fight came to its apex, Luke’s physical being disappeared, Jedi robe flying into the wind, having used so much of the force that the movie hinted he probably died.
Hamill's career-peak performance as the famous Jedi in the 8th film of the "Star Wars" saga had many fans riled up and upset over the way director Rian Johnson portrayed the simple Tatooine farmboy turned savior of the galaxy. However, don't tell that to Mark Hamill, who rather believes Luke is alive and well, and that he actually just teleported to the most peculiar of places.
In an interview with the BBC, Hamill discussed Skywalker’s fate saying “I refuse to believe that he’s gone. My theory is he just teleported to somewhere else and left his robe behind. He teleported to a nudist colony, that’s what I’m hoping.”
Of course, Hamill was half-jokingly making these remarks, but there is also, no doubt, some truth in his statement. He obviously doesn't want to believe Skywalker is gone forever, and, maybe he's hoping that, who knows, maybe director JJ Abrams might bring him back for the concluding chapter in 2019. Luke teleporting into some other place would logically work. Disney XD’s "Star Wars Rebels" brought forth teleportation at the forefront of "Star Wars," so if Abrams does really want to bring back Luke in Episode IX, it wouldn't be so far-fetched an idea, but just don't expect him to be at a nudist colony. No, he's probably in a peaceful, zen-like place where you can hear the sounds of the ocean waves a short distance away, oh, and there definitely is no sight of Rey to be seen.
It would feel almost sacrilege not to bring back Hamill for the final chapter as I am sure many are expecting Abrams to do in his upcoming, much-anticipated film. At the very least, if Luke is dead, just like Obi-Wan Kenobi and Yoda before him, maybe Luke can return as a Force ghost. The aforementioned Jedis all left behind their robes dancing in the wind as well in their death scenes.
