'Star Wars: Episode VIII' plot spoilers news: Leaked script, Luke's new costume; Princes William and Harry doing a cameo?

New rumors about "Star Wars: Episode VIII" production developments have been making the rounds, making fans even more excited to see the next installment premiere.
A leaked script recently made everyone talking because of its outrageous details, including Rey's background. "Star Wars: The Force Awakens" director JJ Abrams caught up with Entertainment Weekly early this month where he mentioned that Rey's parents are not in Episode 7. The leak from Reddit apparently points out that Rey came from a virgin birth, and Luke will tell her this at some point in Episode 8, saying "You are a child of the Force." The leak also claims that "Rey is the reincarnation of Anakin Skywalker," which explains why she is "so crazy powerful with the Force (remember that Anakin blew up the Trade Federation donut ship by himself when he was like 8 years old)."
Meanwhile, Luke Skywalker might be donning a new costume which will look more urban. "His very dark grey cape drops over the top of his shoulders and chest like a shawl. This leaves his right arm free but half of his chest covered by the cape. It's almost similar to the asymmetrical cut of Captain Phasma's cape, but more like a shawl in the way it covers his chest," iDigital Times noted.
As for casting-related news, Express reports that Princes William and Harry "secretly filmed" for cameo roles in Episode 8. The royal siblings recently paid a public visit to Pinewood Studios, which was not much of a surprise since they are both fans of Star Wars. However, after the set cleared out, the two allegedly shot some scenes as stormtroopers with only the essential crew members, producer and director around. According to the publication's source, the director asked the Princes to "get suited," after most of the people there have gone out. Rumor has it that they shot the scene alongside Daisy Ridley who plays Rey and John Boyega who plays Finn. The Princes' spokesperson would "neither confirm nor deny" the speculations, only confirming that they enjoyed their tour.
