On December 16, Star Wars fans will blast off once again to a galaxy far, far away—only this time, it’s with a new set of characters (save for one Sith Lord) in Rogue One: A Star Wars Story. The film’s stars Felicity Jones and Alan Tudyk, director Gareth Edwards, and producer Kathleen Kennedy give readers a glimpse into the making of the film, which is centered on a group of rebels determined to steal the plans for the menacing Death Star. Kennedy reveals the origins of this first “stand-alone” film, while Edwards discusses the detailed planning that went into bringing Darth Vader back to the big screen.
