It turns out the rumors were true! Entertainment Weekly has confirmed that Darth Vader will indeed appear in Gareth Edwards' ROGUE ONE: A STAR WARS STORY, the first three planned spinoff set in the Star Wars universe. There's no word on how much screen time Vader will have in the movie (which is currently undergoing reshoots), but it's been rumored that he'll be a "player in a few scenes and something to fear for the heroes," and that James Earl Jones will be back to provide the voice of the villain.
EW has also unveiled the cover for its upcoming issue, providing us with a fresh look at Felicity Jones as Jyn Erso, Diego Luna as Captain Cassian Andor and K-2SO, the Imperial Enforcer droid voiced by Alan Tudyk.
ROGUE ONE: A STAR WARS STORY opens on December 16, 2016.
